\section{\class{wxAcceleratorTable}}\label{wxacceleratortable}
|
||||
|
||||
An accelerator table allows the application to specify a table of keyboard shortcuts for
|
||||
menus or other commands. On Windows, menu or button commands are supported; on GTK,
|
||||
only menu commands are supported.
|
||||
|
||||
The object {\bf wxNullAcceleratorTable} is defined to be a table with no data, and is the
|
||||
initial accelerator table for a window.

|

\end{verbatim}
|

}
|
||||
|
||||
\wxheading{Remarks}
|
||||
|
||||
An accelerator takes precedence over normal processing and can be a convenient way to program some event handling.
|
||||
For example, you can use an accelerator table to enable a dialog with a multi-line text control to
|
||||
accept CTRL-Enter as meaning `OK' (but not in GTK at present).

\section{\class{wxApp}}\label{wxapp}
|

|

The {\bf wxApp} class represents the application itself. It is used
|
||||
to:
|
||||
|
||||
\begin{itemize}\itemsep=0pt
|
||||
\item set and get application-wide properties;
|
||||
\item implement the windowing system message or event loop;
|
||||
\item initiate application processing via \helpref{wxApp::OnInit}{wxapponinit};
|
||||
\item allow default processing of events not handled by other
|
||||
objects in the application.
|
||||
\end{itemize}
|
||||
|
||||
You should use the macro IMPLEMENT\_APP(appClass) in your application implementation
|
||||
file to tell wxWindows how to create an instance of your application class.
|
||||
|
||||
Use DECLARE\_APP(appClass) in a header file if you want the wxGetApp function (which returns
|
||||
a reference to your application object) to be visible to other files.

This function is called before processing any event and allows the application
|
||||
to preempt the processing of some events. If this method returns $-1$ the event
|
||||
is processed normally, otherwise either {\tt TRUE} or {\tt FALSE} should be
|

returned and the event processing stops immediately considering that the event

had been already processed (for the former return value) or that it is not

the top window.

Returns TRUE if the application has been initialized (i.e. if\rtfsp
|
||||
\helpref{wxApp::OnInit}{wxapponinit} has returned successfully). This can be useful for error
|
||||
message routines to determine which method of output is best for the

current state of the program (some windowing systems may not like

||||
dialogs to pop up before the main loop has been entered).

This function is called when an assert failure occurs, i.e. the condition
|
||||
specified in \helpref{wxASSERT}{wxassert} macro evaluated to {\tt FALSE}.
|
||||
It is only called in debug mode (when {\tt \_\_WXDEBUG\_\_} is defined) as
|
||||
asserts are not left in the release code at all.
|
||||
|
||||
The base class version show the default assert failure dialog box proposing to
|
||||
the user to stop the program, continue or ignore all subsequent asserts.

Called when command line parsing fails (i.e. an incorrect command line option
|
||||
was specified by the user). The default behaviour is to show the program usage
|
||||
text and abort the program.
|
||||
|

set from the command line.
|

\func{void}{OnFatalException}{\void}

This function may be called if something fatal happens: an unhandled

exception under Win32 or a a fatal signal under Unix, for example. However,
|
||||
this will not happen by default: you have to explicitly call
|
||||
\helpref{wxHandleFatalExceptions}{wxhandlefatalexceptions} to enable this.
|
||||
|
||||
Generally speaking, this function should only show a message to the user and
|

work and, in fact, probably won't.

\func{void}{OnQueryEndSession}{\param{wxCloseEvent\& }{event}}
|
||||
|
||||
This is an event handler function called when the operating system or GUI session is
|
||||
about to close down. Typically, an application will try to save unsaved documents
|
||||
at this point.
|
||||
|
||||
If \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto} returns TRUE, the application
|
||||
is allowed to veto the shutdown by calling \helpref{wxCloseEvent::Veto}{wxcloseeventveto}.
|
||||
The application might veto the shutdown after prompting for documents to be saved, and the
|
||||
user has cancelled the save.
|
||||
|
||||
Use the EVT\_QUERY\_END\_SESSION event table macro to handle query end session events.
|
||||
|
||||
You should check whether the application is forcing the deletion of the window
|
||||
using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE,
|
||||
destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
|
||||
If not, it is up to you whether you respond by destroying the window.
|
||||
|
||||
The default handler calls \helpref{wxWindow::Close}{wxwindowclose} on the top-level window,
|
||||
and vetoes the shutdown if Close returns FALSE. This will be sufficient for many applications.
|
||||

|

Yields control to pending messages in the windowing system. This can be useful, for example, when a
|
||||
time-consuming process writes to a text window. Without an occasional
|
||||
yield, the text window will not be updated properly, and on systems with
|
||||
cooperative multitasking, such as Windows 3.1 other processes will not respond.
|
||||
|
||||
Caution should be exercised, however, since yielding may allow the
|
||||
user to perform actions which are not compatible with the current task.
|
||||
Disabling menu items or whole menus during processing can avoid unwanted
|
||||
reentrance of code: see \helpref{::wxSafeYield}{wxsafeyield} for a better
|
||||
function.
|
||||
|
||||
Note that Yield() will not flush the message logs. This is intentional as
|
||||
calling Yield() is usually done to quickly update the screen and popping up a
|
||||
message box dialog may be undesirable. If you do wish to flush the log
|
||||
messages immediately (otherwise it will be done during the next idle loop
|
||||
iteration), call \helpref{wxLog::FlushActive}{wxlogflushactive}.
|
||||
|
||||
Calling Yield() recursively is normally an error and an assert failure is
|
||||
raised in debug build if such situation is detected. However if the the
|
||||
{\it onlyIfNeeded} parameter is {\tt TRUE}, the method will just silently
|
||||
return {\tt FALSE} instead.

\section{\class{wxArray}}\label{wxarray}
|
||||
|
||||
This section describes the so called {\it dynamic arrays}. This is a C
|
||||
array-like data structure i.e. the member access time is constant (and not
|
||||
linear according to the number of container elements as for linked lists). However, these
|
||||
arrays are dynamic in the sense that they will automatically allocate more
|
||||
memory if there is not enough of it for adding a new element. They also perform
|
||||
range checking on the index values but in debug mode only, so please be sure to
|
||||
compile your application in debug mode to use it (see \helpref{debugging overview}{debuggingoverview} for
|
||||
details). So, unlike the arrays in some other
|
||||
languages, attempt to access an element beyond the arrays bound doesn't
|
||||
automatically expand the array but provokes an assertion failure instead in
|
||||
debug build and does nothing (except possibly crashing your program) in the
|
||||
release build.
|
||||
|
||||
The array classes were designed to be reasonably efficient, both in terms of
|
||||
run-time speed and memory consumption and the executable size. The speed of
|
||||
array item access is, of course, constant (independent of the number of elements)
|
||||
making them much more efficient than linked lists (\helpref{wxList}{wxlist}).
|
||||
Adding items to the arrays is also implemented in more or less constant time -
|
||||
but the price is preallocating the memory in advance. In the \helpref{memory management}{wxarraymemorymanagement} section
|
||||
you may find some useful hints about optimizing wxArray memory usage. As for executable size, all
|
||||
wxArray functions are inline, so they do not take {\it any space at all}.
|
||||
|
||||
wxWindows has three different kinds of array. All of them derive from
|
||||
wxBaseArray class which works with untyped data and can not be used directly.
|
||||
The standard macros WX\_DEFINE\_ARRAY(), WX\_DEFINE\_SORTED\_ARRAY() and
|
||||
WX\_DEFINE\_OBJARRAY() are used to define a new class deriving from it. The
|
||||
classes declared will be called in this documentation wxArray, wxSortedArray and
|
||||
wxObjArray but you should keep in mind that no classes with such names actually
|
||||
exist, each time you use one of WX\_DEFINE\_XXXARRAY macro you define a class
|
||||
with a new name. In fact, these names are "template" names and each usage of one
|
||||
of the macros mentioned above creates a template specialization for the given
|
||||
element type.
|
||||
|
||||
wxArray is suitable for storing integer types and pointers which it does not
|
||||
treat as objects in any way, i.e. the element pointed to by the pointer is not
|
||||
deleted when the element is removed from the array. It should be noted that
|
||||
all of wxArray's functions are inline, so it costs strictly nothing to define as
|
||||
many array types as you want (either in terms of the executable size or the
|
||||
speed) as long as at least one of them is defined and this is always the case
|
||||
because wxArrays are used by wxWindows internally. This class has one serious
|
||||
limitation: it can only be used for storing integral types (bool, char, short,
|
||||
int, long and their unsigned variants) or pointers (of any kind). An attempt
|
||||
to use with objects of sizeof() greater than sizeof(long) will provoke a
|
||||
runtime assertion failure, however declaring a wxArray of floats will not (on
|
||||
the machines where sizeof(float) <= sizeof(long)), yet it will {\bf not} work,
|
||||
please use wxObjArray for storing floats and doubles (NB: a more efficient
|
||||
wxArrayDouble class is scheduled for the next release of wxWindows).
|
||||
|
||||
wxSortedArray is a wxArray variant which should be used when searching in the
|
||||
array is a frequently used operation. It requires you to define an additional
|
||||
function for comparing two elements of the array element type and always stores
|
||||
its items in the sorted order (according to this function). Thus, it is
|
||||
\helpref{Index()}{wxarrayindex} function execution time is $O(log(N))$ instead of
|
||||
$O(N)$ for the usual arrays but the \helpref{Add()}{wxarrayadd} method is
|
||||
slower: it is $O(log(N))$ instead of constant time (neglecting time spent in
|
||||
memory allocation routine). However, in a usual situation elements are added to
|
||||
an array much less often than searched inside it, so wxSortedArray may lead to
|
||||
huge performance improvements compared to wxArray. Finally, it should be
|
||||
noticed that, as wxArray, wxSortedArray can be only used for storing integral
|
||||
types or pointers.
|
||||
|
||||
wxObjArray class treats its elements like "objects". It may delete them when
|
||||
they are removed from the array (invoking the correct destructor) and copies
|
||||
them using the objects copy constructor. In order to implement this behaviour
|
||||
the definition of the wxObjArray arrays is split in two parts: first, you should
|
||||
declare the new wxObjArray class using WX\_DECLARE\_OBJARRAY() macro and then
|
||||
you must include the file defining the implementation of template type:
|
||||
<wx/arrimpl.cpp> and define the array class with WX\_DEFINE\_OBJARRAY() macro
|
||||
from a point where the full (as opposed to `forward') declaration of the array
|
||||
elements class is in scope. As it probably sounds very complicated here is an
|
||||
example:
|
||||
|
||||
\begin{verbatim}
|
||||
#include <wx/dynarray.h>
|
||||
|
||||
// we must forward declare the array because it is used inside the class
|
||||
// declaration
|
||||
class MyDirectory;
|
||||
class MyFile;
|
||||
|
||||
// this defines two new types: ArrayOfDirectories and ArrayOfFiles which can be
|
||||
// now used as shown below
|
||||
WX_DECLARE_OBJARRAY(MyDirectory, ArrayOfDirectories);
|
||||
WX_DECLARE_OBJARRAY(MyFile, ArrayOfFiles);
|
||||
|
||||
class MyDirectory
|
||||
{
|
||||
...
|
||||
ArrayOfDirectories m_subdirectories; // all subdirectories
|
||||
ArrayOfFiles m_files; // all files in this directory
|
||||
};
|
||||
|
||||
...
|
||||
|
||||
// now that we have MyDirectory declaration in scope we may finish the
|
||||
// definition of ArrayOfDirectories -- note that this expands into some C++
|
||||
// code and so should only be compiled once (i.e., don't put this in the
|
||||
// header, but into a source file or you will get linking errors)
|
||||
#include <wx/arrimpl.cpp> // this is a magic incantation which must be done!
|
||||
WX_DEFINE_OBJARRAY(ArrayOfDirectories);
|
||||
|
||||
// that's all!
|
||||
\end{verbatim}
|
||||
|
||||
It is not as elegant as writing
|
||||
|
||||
\begin{verbatim}
|
||||
typedef std::vector<MyDirectory> ArrayOfDirectories;
|
||||
\end{verbatim}
|
||||
|
||||
but is not that complicated and allows the code to be compiled with any, however
|
||||
dumb, C++ compiler in the world.
|
||||
|
||||
Things are much simpler for wxArray and wxSortedArray however: it is enough
|
||||
just to write
|
||||
|
||||
\begin{verbatim}
|
||||
WX_DEFINE_ARRAY(MyDirectory *, ArrayOfDirectories);
|
||||
WX_DEFINE_SORTED_ARRAY(MyFile *, ArrayOfFiles);

\membersection{Macros for template array definition}
|
||||
|
||||
To use an array you must first define the array class. This is done with the
|
||||
help of the macros in this section. The class of array elements must be (at
|
||||
least) forward declared for WX\_DEFINE\_ARRAY, WX\_DEFINE\_SORTED\_ARRAY and
|
||||
WX\_DECLARE\_OBJARRAY macros and must be fully declared before you use
|
||||
WX\_DEFINE\_OBJARRAY macro.

\membersection{Constructors and destructors}
|
||||
|
||||
Array classes are 100\% C++ objects and as such they have the appropriate copy
|
||||
constructors and assignment operators. Copying wxArray just copies the elements
|
||||
but copying wxObjArray copies the arrays items. However, for memory-efficiency
|
||||
sake, neither of these classes has virtual destructor. It is not very important
|
||||
for wxArray which has trivial destructor anyhow, but it does mean that you
|
||||
should avoid deleting wxObjArray through a wxBaseArray pointer (as you would
|
||||
never use wxBaseArray anyhow it shouldn't be a problem) and that you should not
|
||||
derive your own classes from the array classes.

\membersection{Memory management}\label{wxarraymemorymanagement}
|
||||
|
||||
Automatic array memory management is quite trivial: the array starts by
|
||||
preallocating some minimal amount of memory (defined by
|
||||
WX\_ARRAY\_DEFAULT\_INITIAL\_SIZE) and when further new items exhaust already
|
||||
allocated memory it reallocates it adding 50\% of the currently allocated
|
||||
amount, but no more than some maximal number which is defined by
|
||||
ARRAY\_MAXSIZE\_INCREMENT constant. Of course, this may lead to some memory
|
||||
being wasted (ARRAY\_MAXSIZE\_INCREMENT in the worst case, i.e. 4Kb in the
|
||||
current implementation), so the \helpref{Shrink()}{wxarrayshrink} function is
|
||||
provided to deallocate the extra memory. The \helpref{Alloc()}{wxarrayalloc}
|
||||
function can also be quite useful if you know in advance how many items you are
|
||||
going to put in the array and will prevent the array code from reallocating the
|
||||
memory more times than needed.

\membersection{Number of elements and simple item access}
|
||||
|
||||
Functions in this section return the total number of array elements and allow to
|

retrieve them - possibly using just the C array indexing $[]$ operator which
|
||||
does exactly the same as \helpref{Item()}{wxarrayitem} method.

\func{}{WX\_DEFINE\_ARRAY}{\param{}{T}, \param{}{name}}
|

\func{}{WX\_DEFINE\_EXPORTED\_ARRAY}{\param{}{T}, \param{}{name}}
|
||||
|
||||
\func{}{WX\_DEFINE\_USER\_EXPORTED\_ARRAY}{\param{}{T}, \param{}{name}, \param{}{exportspec}}
|
||||
|
||||
This macro defines a new array class named {\it name} and containing the
|
||||
elements of type {\it T}. The second form is used when compiling wxWindows as
|
||||
a DLL under Windows and array needs to be visible outside the DLL. The third is
|
||||
needed for exporting an array from a user DLL.
|
||||
|
||||
Example:
|
||||
|
||||
\begin{verbatim}
|
||||
WX_DEFINE_ARRAY(int, wxArrayInt);
|
||||
|
||||
class MyClass;
|
||||
WX_DEFINE_ARRAY(MyClass *, wxArrayOfMyClass);
|
||||
\end{verbatim}
|
||||
|
||||
Note that wxWindows predefines the following standard array classes: wxArrayInt,
|
||||
wxArrayLong and wxArrayPtrVoid.
|
||||
|
||||
\membersection{WX\_DEFINE\_SORTED\_ARRAY}\label{wxdefinesortedarray}
|
||||
|
||||
\func{}{WX\_DEFINE\_SORTED\_ARRAY}{\param{}{T}, \param{}{name}}
|
||||
|
||||
\func{}{WX\_DEFINE\_SORTED\_EXPORTED\_ARRAY}{\param{}{T}, \param{}{name}}
|
||||
|
||||
\func{}{WX\_DEFINE\_SORTED\_USER\_EXPORTED\_ARRAY}{\param{}{T}, \param{}{name}}
|
||||
|
||||
This macro defines a new sorted array class named {\it name} and containing
|
||||
the elements of type {\it T}. The second form is used when compiling wxWindows as
|
||||
a DLL under Windows and array needs to be visible outside the DLL. The third is
|
||||
needed for exporting an array from a user DLL.
|
||||
|
||||
Example:
|
||||
|
||||
\begin{verbatim}
|
||||
WX_DEFINE_SORTED_ARRAY(int, wxSortedArrayInt);
|
||||
|
||||
class MyClass;
|
||||
WX_DEFINE_SORTED_ARRAY(MyClass *, wxArrayOfMyClass);
|
||||
\end{verbatim}
|
||||
|
||||
You will have to initialize the objects of this class by passing a comparison
|
||||
function to the array object constructor like this:
|
||||
|
||||
\begin{verbatim}
|
||||
int CompareInts(int n1, int n2)
|
||||
{
|
||||
return n1 - n2;
|
||||
}
|
||||
|
||||
wxSortedArrayInt sorted(CompareInts);
|
||||
|
||||
int CompareMyClassObjects(MyClass *item1, MyClass *item2)
|
||||
{
|
||||
// sort the items by their address...
|
||||
return Stricmp(item1->GetAddress(), item2->GetAddress());
|
||||
}
|
||||
|
||||
wxArrayOfMyClass another(CompareMyClassObjects);
|
||||
\end{verbatim}
|
||||
|
||||
\membersection{WX\_DECLARE\_OBJARRAY}\label{wxdeclareobjarray}
|

\func{}{WX\_DECLARE\_OBJARRAY}{\param{}{T}, \param{}{name}}
|
||||

\func{}{WX\_DECLARE\_EXPORTED\_OBJARRAY}{\param{}{T}, \param{}{name}}
|
||||
|
||||
\func{}{WX\_DECLARE\_USER\_EXPORTED\_OBJARRAY}{\param{}{T}, \param{}{name}}
|
||||
|
||||
This macro declares a new object array class named {\it name} and containing
|
||||
the elements of type {\it T}. The second form is used when compiling wxWindows as
|
||||
a DLL under Windows and array needs to be visible outside the DLL. The third is
|
||||
needed for exporting an array from a user DLL.
|
||||
|
||||
Example:
|
||||
|
||||
\begin{verbatim}
|
||||
class MyClass;
|
||||
WX_DEFINE_OBJARRAY(MyClass, wxArrayOfMyClass); // note: not "MyClass *"!
|
||||
\end{verbatim}
|
||||
|
||||
You must use \helpref{WX\_DEFINE\_OBJARRAY()}{wxdefineobjarray} macro to define
|
||||
the array class - otherwise you would get link errors.
|
||||
|
||||
\membersection{WX\_DEFINE\_OBJARRAY}\label{wxdefineobjarray}
|
||||
|
||||
\func{}{WX\_DEFINE\_OBJARRAY}{\param{}{name}}
|
||||
|
||||
\func{}{WX\_DEFINE\_EXPORTED\_OBJARRAY}{\param{}{name}}
|
||||
|
||||
\func{}{WX\_DEFINE\_USER\_EXPORTED\_OBJARRAY}{\param{}{name}}
|
||||
|
||||
This macro defines the methods of the array class {\it name} not defined by the
|
||||
\helpref{WX\_DECLARE\_OBJARRAY()}{wxdeclareobjarray} macro. You must include the
|
||||
file <wx/arrimpl.cpp> before using this macro and you must have the full
|
||||
declaration of the class of array elements in scope! If you forget to do the
|
||||
first, the error will be caught by the compiler, but, unfortunately, many
|
||||
compilers will not give any warnings if you forget to do the second - but the
|
||||
objects of the class will not be copied correctly and their real destructor will
|
||||
not be called. The latter two forms are merely aliases of the first to satisfy
|
||||
some people's sense of symmetry when using the exported declarations.
|
||||
|
||||
Example of usage:
|
||||
|
||||
\begin{verbatim}
|
||||
// first declare the class!
|
||||
class MyClass
|
||||
{
|
||||
public:
|
||||
MyClass(const MyClass&);
|
||||
|
||||
...
|
||||
|
||||
virtual ~MyClass();
|
||||
};
|
||||
|
||||
#include <wx/arrimpl.cpp>
|
||||
WX_DEFINE_OBJARRAY(wxArrayOfMyClass);
|
||||
\end{verbatim}
|
||||
|
||||
\membersection{WX\_APPEND\_ARRAY}\label{wxappendarray}
|
||||
|
||||
\func{void}{WX\_APPEND\_ARRAY}{\param{wxArray\& }{array}, \param{wxArray\& }{other}}
|
||||
|
||||
This macro may be used to append all elements of the {\it other} array to the
|
||||
{\it array}. The two arrays must be of the same type.
|
||||
|
||||
\membersection{WX\_CLEAR\_ARRAY}\label{wxcleararray}
|
||||
|
||||
\func{void}{WX\_CLEAR\_ARRAY}{\param{wxArray\& }{array}}
|
||||
|
||||
This macro may be used to delete all elements of the array before emptying it.
|
||||
It can not be used with wxObjArrays - but they will delete their elements anyhow
|
||||
when you call Empty().
|
||||
|
||||
\membersection{Default constructors}\label{wxarrayctordef}
|
||||
|
||||
\func{}{wxArray}{\void}
|
||||
|
||||
\func{}{wxObjArray}{\void}
|
||||
|
||||
Default constructor initializes an empty array object.
|
||||
|
||||
\func{}{wxSortedArray}{\param{int (*)(T first, T second)}{compareFunction}}
|
||||
|
||||
There is no default constructor for wxSortedArray classes - you must initialize it
|
||||
with a function to use for item comparison. It is a function which is passed
|
||||
two arguments of type {\it T} where {\it T} is the array element type and which
|
||||
should return a negative, zero or positive value according to whether the first
|
||||
element passed to it is less than, equal to or greater than the second one.
|
||||
|
||||
\membersection{wxArray copy constructor and assignment operator}\label{wxarrayctorcopy}
|
||||
|
||||
\func{}{wxArray}{\param{const wxArray\& }{array}}
|
||||
|
||||
\func{}{wxSortedArray}{\param{const wxSortedArray\& }{array}}
|
||||
|
||||
\func{}{wxObjArray}{\param{const wxObjArray\& }{array}}
|
||||
|
||||
\func{wxArray\&}{operator$=$}{\param{const wxArray\& }{array}}
|
||||
|
||||
\func{wxSortedArray\&}{operator$=$}{\param{const wxSortedArray\& }{array}}
|
||||
|
||||
\func{wxObjArray\&}{operator$=$}{\param{const wxObjArray\& }{array}}
|
||||
|
||||
The copy constructors and assignment operators perform a shallow array copy
|
||||
(i.e. they don't copy the objects pointed to even if the source array contains
|
||||
the items of pointer type) for wxArray and wxSortedArray and a deep copy (i.e.
|
||||
the array element are copied too) for wxObjArray.
|
||||
|
||||
\membersection{wxArray::\destruct{wxArray}}\label{wxarraydtor}
|
||||
|
||||
\func{}{\destruct{wxArray}}{\void}
|
||||
|
||||
\func{}{\destruct{wxSortedArray}}{\void}
|
||||
|
||||
\func{}{\destruct{wxObjArray}}{\void}
|
||||
|
||||
The wxObjArray destructor deletes all the items owned by the array. This is not
|
||||
done by wxArray and wxSortedArray versions - you may use
|
||||
\helpref{WX\_CLEAR\_ARRAY}{wxcleararray} macro for this.
|
||||
|
||||
\membersection{wxArray::Add}\label{wxarrayadd}
|
||||
|
||||
\func{void}{Add}{\param{T }{item}, \param{size\_t}{ copies = $1$}}
|
||||
|
||||
\func{void}{Add}{\param{T *}{item}}
|
||||
|
||||
\func{void}{Add}{\param{T \&}{item}, \param{size\_t}{ copies = $1$}}
|
||||
|
||||
Appends the given number of {\it copies} of the {\it item} to the array
|
||||
consisting of the elements of type {\it T}.
|
||||
|
||||
The first version is used with wxArray and wxSortedArray. The second and the
|
||||
third are used with wxObjArray. There is an important difference between
|
||||
them: if you give a pointer to the array, it will take ownership of it, i.e.
|
||||
will delete it when the item is deleted from the array. If you give a reference
|
||||
to the array, however, the array will make a copy of the item and will not take
|
||||
ownership of the original item. Once again, it only makes sense for wxObjArrays
|
||||
because the other array types never take ownership of their elements. Also note
|
||||
that you cannot append more than one pointer as reusing it would lead to
|
||||
deleting it twice (or more) and hence to a crash.
|
||||
|
||||
You may also use \helpref{WX\_APPEND\_ARRAY}{wxappendarray} macro to append all
|
||||
elements of one array to another one but it is more efficient to use
|
||||
{\it copies} parameter and modify the elements in place later if you plan to
|
||||
append a lot of items.
|
||||
|
||||
\membersection{wxArray::Alloc}\label{wxarrayalloc}
|
||||
|
||||
\func{void}{Alloc}{\param{size\_t }{count}}
|
||||
|
||||
Preallocates memory for a given number of array elements. It is worth calling
|
||||
when the number of items which are going to be added to the array is known in
|
||||
advance because it will save unneeded memory reallocation. If the array already
|
||||
has enough memory for the given number of items, nothing happens.
|
||||
|
||||
\membersection{wxArray::Clear}\label{wxarrayclear}
|
||||
|
||||
\func{void}{Clear}{\void}
|
||||
|
||||
This function does the same as \helpref{Empty()}{wxarrayempty} and additionally
|
||||
frees the memory allocated to the array.
|
||||
|
||||
\membersection{wxArray::Count}\label{wxarraycount}
|
||||
|
||||
\constfunc{size\_t}{Count}{\void}
|
||||
|
||||
Same as \helpref{GetCount()}{wxarraygetcount}. This function is deprecated -
|
||||
it exists only for compatibility.
|
||||
|
||||
\membersection{wxObjArray::Detach}\label{wxobjarraydetach}
|
||||
|
||||
\func{T *}{Detach}{\param{size\_t }{index}}
|
||||
|
||||
Removes the element from the array, but, unlike,
|
||||
\helpref{Remove()}{wxarrayremove} doesn't delete it. The function returns the
|
||||
pointer to the removed element.
|
||||
|
||||
\membersection{wxArray::Empty}\label{wxarrayempty}
|
||||
|
||||
\func{void}{Empty}{\void}
|
||||
|
||||
Empties the array. For wxObjArray classes, this destroys all of the array
|
||||
elements. For wxArray and wxSortedArray this does nothing except marking the
|
||||
array of being empty - this function does not free the allocated memory, use
|
||||
\helpref{Clear()}{wxarrayclear} for this.
|
||||
|
||||
\membersection{wxArray::GetCount}\label{wxarraygetcount}
|
||||
|
||||
\constfunc{size\_t}{GetCount}{\void}
|
||||
|
||||
Return the number of items in the array.
|
||||
|
||||
\membersection{wxArray::Index}\label{wxarrayindex}
|
||||
|
||||
\func{int}{Index}{\param{T\& }{item}, \param{bool }{searchFromEnd = FALSE}}
|
||||
|
||||
\func{int}{Index}{\param{T\& }{item}}
|
||||
|
||||
The first version of the function is for wxArray and wxObjArray, the second is
|
||||
for wxSortedArray only.
|
||||
|
||||
Searches the element in the array, starting from either beginning or the end
|
||||
depending on the value of {\it searchFromEnd} parameter. wxNOT\_FOUND is
|
||||
returned if the element is not found, otherwise the index of the element is
|
||||
returned.
|
||||
|
||||
Linear search is used for the wxArray and wxObjArray classes but binary search
|
||||
in the sorted array is used for wxSortedArray (this is why searchFromEnd
|
||||
parameter doesn't make sense for it).
|
||||
|
||||
{\bf NB:} even for wxObjArray classes, the operator==() of the elements in the
|
||||
array is {\bf not} used by this function. It searches exactly the given
|
||||
element in the array and so will only succeed if this element had been
|
||||
previously added to the array, but fail even if another, identical, element is
|
||||
in the array.
|
||||
|
||||
\membersection{wxArray::Insert}\label{wxarrayinsert}
|
||||
|
||||
\func{void}{Insert}{\param{T }{item}, \param{size\_t }{n}, \param{size\_t }{copies = $1$}}
|
||||
|
||||
\func{void}{Insert}{\param{T *}{item}, \param{size\_t }{n}}
|
||||
|

\func{void}{Insert}{\param{T \&}{item}, \param{size\_t }{n}, \param{size\_t }{copies = $1$}}
|
||||
|
||||
Insert the given number of {\it copies} of the {\it item} into the array before
|
||||
the existing item {\it n} - thus, {\it Insert(something, 0u)} will insert an
|
||||
item in such way that it will become the first array element.

\membersection{wxArray::IsEmpty}\label{wxarrayisempty}
|

Returns the item at the given position in the array. If {\it index} is out of
|

bounds, an assert failure is raised in the debug builds but nothing special is
|

done in the release build.
|

\constfunc{T\&}{Last}{\void}
|

Returns the last element in the array, i.e. is the same as Item(GetCount() - 1).
|
||||
An assert failure is raised in the debug mode if the array is empty.
|
||||
|
||||
The returned value is of type "reference to the array element type" for all of

\membersection{wxArray::Remove}\label{wxarrayremove}
|

\func{\void}{Remove}{\param{T }{item}}
|
||||
|
||||
Removes an element from the array by value: the first item of the
|
||||
array equal to {\it item} is removed, an assert failure will result from an
|
||||
attempt to remove an item which doesn't exist in the array.
|
||||
|
||||
When an element is removed from wxObjArray it is deleted by the array - use
|
||||
\helpref{Detach()}{wxobjarraydetach} if you don't want this to happen. On the
|
||||
other hand, when an object is removed from a wxArray nothing happens - you
|
||||
should delete it manually if required:
|

|
||||
\begin{verbatim}

|
||||
|
||||
\func{\void}{RemoveAt}{\param{size\_t }{index}, \param{size\_t }{count = $1$}}
|
||||
|
||||
Removes {\it count} elements starting at {\it index} from the array. When an
|
||||
element is removed from wxObjArray it is deleted by the array - use
|
||||
\helpref{Detach()}{wxobjarraydetach} if you don't want this to happen. On

||||
\membersection{wxArray::Shrink}\label{wxarrayshrink}
|
||||
|
||||
\func{void}{Shrink}{\void}
|
||||
|
||||
Frees all memory unused by the array. If the program knows that no new items
|
||||
will be added to the array it may call Shrink() to reduce its memory usage.
|
||||
However, if a new item is added to the array, some extra memory will be
|

allocated again.

\begin{verbatim}
|

template int CMPFUNC(T *first, T *second);
|

where {\it T} is the type of the array elements. I.e. it is a function returning
|

{\it int} which is passed two arguments of type {\it T *}.
|
||||
|
||||
Sorts the array using the specified compare function: this function should
|

return a negative, zero or positive value according to whether the first element
|

\section{\class{wxArrayString}}\label{wxarraystring}
|

|
||||
wxArrayString is an efficient container for storing
|
||||
\helpref{wxString}{wxstring} objects. It has the same features as all
|
||||
\helpref{wxArray}{wxarray} classes, i.e. it dynamically expands when new items
|
||||
are added to it (so it is as easy to use as a linked list), but the access
|
||||
time to the elements is constant, instead of being linear in number of
|
||||
elements as in the case of linked lists. It is also very size efficient and
|
||||
doesn't take more space than a C array {\it wxString[]} type (wxArrayString
|
||||
uses its knowledge of internals of wxString class to achieve this).
|
||||
|
||||
This class is used in the same way as other dynamic \helpref{arrays}{wxarray},
|
||||
except that no {\it WX\_DEFINE\_ARRAY} declaration is needed for it. When a
|
||||
string is added or inserted in the array, a copy of the string is created, so
|
||||
the original string may be safely deleted (e.g. if it was a {\it char *}
|
||||
pointer the memory it was using can be freed immediately after this). In
|
||||
general, there is no need to worry about string memory deallocation when using
|
||||
this class - it will always free the memory it uses itself.
|
||||
|
||||
The references returned by \helpref{Item}{wxarraystringitem},
|
||||
\helpref{Last}{wxarraystringlast} or
|
||||
\helpref{operator[]}{wxarraystringoperatorindex} are not constant, so the
|
||||
array elements may be modified in place like this
|
||||
|
||||
\begin{verbatim}
|
||||
array.Last().MakeUpper();
|
||||
\end{verbatim}
|
||||
|
||||
There is also a variant of wxArrayString called wxSortedArrayString which has
|
||||
exactly the same methods as wxArrayString, but which always keeps the string
|
||||
in it in (alphabetical) order. wxSortedArrayString uses binary search in its
|
||||
\helpref{Index}{wxarraystringindex} function (instead of linear search for
|
||||
wxArrayString::Index) which makes it much more efficient if you add strings to
|
||||
the array rarely (because, of course, you have to pay for Index() efficiency
|
||||
by having Add() be slower) but search for them often. Several methods should
|
||||
not be used with sorted array (basically, all which break the order of items)
|
||||
which is mentioned in their description.
|
||||
|
||||
Final word: none of the methods of wxArrayString is virtual including its
|
||||
destructor, so this class should not be used as a base class.
|
||||
|
||||
\wxheading{Derived from}
|
||||
|
||||
Although this is not true strictly speaking, this class may be considered as a
|
||||
specialization of \helpref{wxArray}{wxarray} class for the wxString member
|
||||
data: it is not implemented like this, but it does have all of the wxArray
|
||||
functions.

Destructor frees memory occupied by the array strings. For the performance

\func{wxString\&}{operator[]}{\param{size\_t }{nIndex}}
|

Return the array element at position {\it nIndex}. An assert failure will

result from an attempt to access an element beyond the end of array in debug

|
||||
|
||||
Appends the given number of {\it copies} of the new item {\it str} to the
|
||||
array and returns the index of the first new item in the array.
|
||||
|
||||
{\bf Warning:} For sorted arrays, the index of the inserted item will not be,
|
||||
in general, equal to \helpref{GetCount()}{wxarraystringgetcount} - 1 because
|

the item is inserted at the correct position to keep the array sorted and not

appended.

\membersection{wxArrayString::Alloc}\label{wxarraystringalloc}

\func{void}{Alloc}{\param{size\_t }{nCount}}
|

\constfunc{size\_t}{Count}{\void}
|

|

Returns the number of items in the array. This function is deprecated and is

\helpref{GetCount}{wxarraystringgetcount} instead.
|
||||
|
||||
\membersection{wxArrayString::Empty}\label{wxarraystringempty}
|
||||
|
||||
\func{void}{Empty}{\void}
|
||||
|
||||
Empties the array: after a call to this function
|
||||
\helpref{GetCount}{wxarraystringgetcount} will return $0$. However, this
|
||||
function does not free the memory used by the array and so should be used when
|
||||
the array is going to be reused for storing other strings. Otherwise, you
|
||||
should use \helpref{Clear}{wxarraystringclear} to empty the array and free
|
||||
memory.
|
||||
|
||||
\membersection{wxArrayString::GetCount}\label{wxarraystringgetcount}
|
||||
|

\constfunc{size\_t}{GetCount}{\void}

||||
|
||||
Returns the number of items in the array.

\membersection{wxArrayString::Index}\label{wxarraystringindex}
|
||||
|
||||
\func{int}{Index}{\param{const char *}{ sz}, \param{bool}{ bCase = TRUE}, \param{bool}{ bFromEnd = FALSE}}
|
||||
|
||||
Search the element in the array, starting from the beginning if
|
||||
{\it bFromEnd} is FALSE or from end otherwise. If {\it bCase}, comparison is
|
||||
case sensitive (default), otherwise the case is ignored.
|
||||
|
||||
This function uses linear search for wxArrayString and binary search for
|
||||
wxSortedArrayString, but it ignores the {\it bCase} and {\it bFromEnd}
|
||||
parameters in the latter case.
|
||||
|
||||
Returns index of the first item matched or wxNOT\_FOUND if there is no match.
|
||||
|
||||
\membersection{wxArrayString::Insert}\label{wxarraystringinsert}
|
||||
|
||||
\func{void}{Insert}{\param{const wxString\& }{str}, \param{size\_t}{ nIndex}, \param{size\_t }{copies = $1$}}
|
||||
|
||||
Insert the given number of {\it copies} of the new element in the array before the position {\it nIndex}. Thus, for
|
||||
example, to insert the string in the beginning of the array you would write
|
||||
|
||||
\begin{verbatim}
|
||||
Insert("foo", 0);
|
||||
\end{verbatim}
|
||||
|
||||
If {\it nIndex} is equal to {\it GetCount()} this function behaves as
|
||||
\helpref{Add}{wxarraystringadd}.
|
||||
|
||||
{\bf Warning:} this function should not be used with sorted arrays because it
|
||||
could break the order of items and, for example, subsequent calls to
|
||||
\helpref{Index()}{wxarraystringindex} would then not work!
|
||||
|
||||
\membersection{wxArrayString::IsEmpty}\label{wxarraystringisempty}
|
||||
|
||||
\func{}{IsEmpty}{}
|
||||
|
||||
Returns TRUE if the array is empty, FALSE otherwise. This function returns the
|
||||
same result as {\it GetCount() == 0} but is probably easier to read.
|
||||
|
||||
\membersection{wxArrayString::Item}\label{wxarraystringitem}
|
||||
|
||||
\constfunc{wxString\&}{Item}{\param{size\_t }{nIndex}}
|
||||
|
||||
Return the array element at position {\it nIndex}. An assert failure will
|
||||
result from an attempt to access an element beyond the end of array in debug
|
||||
mode, but no check is done in release mode.
|
||||
|
||||
See also \helpref{operator[]}{wxarraystringoperatorindex} for the operator
|
||||
version.
|
||||
|
||||
\membersection{wxArrayString::Last}\label{wxarraystringlast}
|
||||
|
||||
\func{}{Last}{}
|
||||
|
||||
Returns the last element of the array. Attempt to access the last element of
|
||||
an empty array will result in assert failure in debug build, however no checks
|
||||
are done in release mode.
|
||||
|
||||
\membersection{wxArrayString::Remove}\label{wxarraystringremove}
|
||||
|
||||
\func{void}{Remove}{\param{const char *}{ sz}}
|
||||
|
||||
Removes the first item matching this value. An assert failure is provoked by
|
||||
an attempt to remove an element which does not exist in debug build.
|
||||
|
||||
See also: \helpref{Index}{wxarraystringindex}
|
||||
|
||||
\func{void}{Remove}{\param{size\_t }{nIndex}, \param{size\_t }{count = $1$}}

||||
\membersection{wxArrayString::Shrink}\label{wxarraystringshrink}
|
||||
|
||||
\func{void}{Shrink}{\void}

Releases the extra memory allocated by the array. This function is useful to
|
||||
minimize the array memory consumption.

\func{void}{Sort}{\param{bool}{ reverseOrder = FALSE}}
|
||||
|
||||
Sorts the array in alphabetical order or in reverse alphabetical order if
|
||||
{\it reverseOrder} is TRUE.
|
||||
|
||||
{\bf Warning:} this function should not be used with sorted array because it
|
||||
could break the order of items and, for example, subsequent calls to
|
||||
\helpref{Index()}{wxarraystringindex} would then not work!
|
||||
|
||||
\func{void}{Sort}{\param{CompareFunction }{compareFunction}}
|
||||
|
||||
Sorts the array using the specified {\it compareFunction} for item comparison.
|
||||
{\it CompareFunction} is defined as a function taking two {\it const
|
||||
wxString\&} parameters and returning an {\it int} value less than, equal to or
|
||||
greater than 0 if the first string is less than, equal to or greater than the

\section{\class{wxArtProvider}}\label{wxartprovider}
|
||||
|
||||
wxArtProvider class is used to customize the look of wxWindows application.
|
||||
When wxWindows need to display an icon or a bitmap (e.g. in the standard file
|
||||
dialog), it does not use hard-coded resource but asks wxArtProvider for it
|
||||
instead. This way the users can plug in own wxArtProvider class and easily
|
||||
replace standard art with his/her own version. It is easy thing to do: all
|
||||
that is needed is to derive a class from wxArtProvider, override it's
|
||||
\helpref{CreateBitmap}{wxartprovidercreatebitmap} method and register the
|
||||
provider with
|
||||
\helpref{wxArtProvider::PushProvider}{wxartproviderpushprovider}:
|
||||
|
||||
\begin{verbatim}
|
||||
class MyProvider : public wxArtProvider
|
||||
{
|
||||
protected:
|
||||
wxBitmap CreateBitmap(const wxArtID& id,
|
||||
const wxArtClient& client,
|
||||
const wxSize size)
|
||||
{ ... }
|
||||
};
|
||||
...
|
||||
wxArtProvider::PushProvider(new MyProvider);
|
||||
\end{verbatim}
|
||||
|
||||
There's another way of taking advantage of this class: you can use it in your code and use
|
||||
platform native icons as provided by
|
||||
\helpref{wxArtProvider::GetBitmap}{wxartprovidergetbitmap} or
|
||||
\helpref{wxArtProvider::GetIcon}{wxartprovidergeticon} (NB: this is not yet really
|
||||
possible as of wxWindows 2.3.3, the set of wxArtProvider bitmaps is too
|
||||
small).
|
||||
|
||||
\membersection{Identifying art resources}
|
||||
|
||||
Every bitmap is known to wxArtProvider under an unique ID that is used by when
|
||||
requesting a resource from it. The ID is represented by wxArtID type and can
|
||||
have one of these predefined values (you can see bitmaps represented by these
|
||||
constants in the \helpref{artprov}{sampleartprovider} sample):

|

|
||||
Client is the entity that calls wxArtProvider's GetBitmap or GetIcon
|
||||
function. It is represented by wxClientID type and can have one of these
|
||||
values:
|
||||
\begin{itemize}\itemsep=0pt
|
||||
\item wxART\_TOOLBAR
|
||||
\item wxART\_MENU
|
||||
\item wxART\_FRAME\_ICON
|
||||
\item wxART\_CMN\_DIALOG
|
||||
\item wxART\_HELP\_BROWSER
|
||||
\item wxART\_MESSAGE\_BOX
|
||||
\item wxART\_OTHER (used for all requests that don't fit into any of the categories above)
|
||||
\end{itemize}
|
||||
Client ID servers as a hint to wxArtProvider that is supposed to help it to
|
||||
choose the best looking bitmap. For example it is often desirable to use
|
||||
slightly different icons in menus and toolbars even though they represent the
|
||||
same action (e.g. {\tt wx\_ART\_FILE\_OPEN}). Remember that this is really
|
||||
only a hint for wxArtProvider -- it is common that
|
||||
\helpref{wxArtProvider::GetBitmap}{wxartprovidergetbitmap}
|
||||
returns identical bitmap for different {\it client} values!

\section{\class{wxAutomationObject}}\label{wxautomationobject}
|
||||
|
||||
The {\bf wxAutomationObject} class represents an OLE automation object containing a single data member,
|
||||
an IDispatch pointer. It contains a number of functions that make it easy to perform
|
||||
automation operations, and set and get properties. The class makes heavy use of the \helpref{wxVariant}{wxvariant} class.
|
||||
|
||||
The usage of these classes is quite close to OLE automation usage in Visual Basic. The API is
|
||||
high-level, and the application can specify multiple properties in a single string. The following example
|
||||
gets the current Excel instance, and if it exists, makes the active cell bold.
|
||||
|
||||
{\small
|
||||
\begin{verbatim}
|
||||
wxAutomationObject excelObject;
|
||||
if (excelObject.GetInstance("Excel.Application"))
|
||||
excelObject.PutProperty("ActiveCell.Font.Bold", TRUE);
|
||||
\end{verbatim}
|
||||
}
|
||||
|
||||
Note that this class works under Windows only, and currently only for Visual C++.

|
||||
\constfunc{wxVariant}{CallMethod}{\param{const wxString\&}{ method}, \param{...}{}}
|
||||
|
||||
Calls an automation method for this object. The first form takes a method name, number of
|
||||
arguments, and an array of variants. The second form takes a method name and zero to six
|
||||
constant references to variants. Since the variant class has constructors for the basic
|
||||
data types, and C++ provides temporary objects automatically, both of the following lines
|
||||
are syntactically valid:
|
||||
|
||||
{\small
|
||||
\begin{verbatim}
|
||||
wxVariant res = obj.CallMethod("Sum", wxVariant(1.2), wxVariant(3.4));

||||
wxVariant res = obj.CallMethod("Sum", 1.2, 3.4);
|
||||
\end{verbatim}
|
||||
}
|
||||
|

Note that {\it method} can contain dot-separated property names, to save the application

needing to call GetProperty several times using several temporary objects. For example:
|

{\small

|
||||
|

\constfunc{bool}{GetInstance}{\param{const wxString\&}{ classId}}
|
||||
|
||||
Retrieves the current object associated with a class id, and attaches the IDispatch pointer
|
||||
to this object. Returns TRUE if a pointer was successfully retrieved, FALSE otherwise.
|
||||
|
||||
Note that this cannot cope with two instances of a given OLE object being active simultaneously,
|
||||
such as two copies of Excel running. Which object is referenced cannot currently be specified.

|
||||
|
||||
Retrieves a property from this object, assumed to be a dispatch pointer, and initialises {\it obj} with it.
|
||||
To avoid having to deal with IDispatch pointers directly, use this function in preference
|
||||
to \helpref{wxAutomationObject::GetProperty}{wxautomationobjectgetproperty} when retrieving objects

from other objects.

|

|
||||
\func{}{wxBitmap}{\void}
|
||||
|
||||
Default constructor.
|
||||
|
||||
\func{}{wxBitmap}{\param{const wxBitmap\& }{bitmap}}
|
||||
|
||||
Copy constructor.
|
||||
|
||||
\func{}{wxBitmap}{\param{void*}{ data}, \param{int}{ type}, \param{int}{ width}, \param{int}{ height}, \param{int}{ depth = -1}}
|
||||
|
||||
Creates a bitmap from the given data which is interpreted in platform-dependent
|
||||
manner.
|
||||
|
||||
\func{}{wxBitmap}{\param{const char}{ bits[]}, \param{int}{ width}, \param{int}{ height}\\
|
||||
\param{int}{ depth = 1}}
|
||||
|
||||
Creates a bitmap from an array of bits.
|
||||
|
||||
You should only use this function for monochrome bitmaps ({\it depth} 1) in
|
||||
portable programs: in this case the {\it bits} parameter should contain an XBM
|
||||
image.
|
||||
|
||||
For other bit depths, the behaviour is platform dependent: under Windows, the
|
||||
data is passed without any changes to the underlying {\tt CreateBitmap()} API.
|
||||
Under other platforms, only monochrome bitmaps may be created using this
|
||||
constructor and \helpref{wxImage}{wximage} should be used for creating colour
|
||||
bitmaps from static data.
|
||||
|
||||
\func{}{wxBitmap}{\param{int}{ width}, \param{int}{ height}, \param{int}{ depth = -1}}
|
||||
|
||||
Creates a new bitmap. A depth of -1 indicates the depth of the current screen
|
||||
or visual. Some platforms only support 1 for monochrome and -1 for the current
|
||||
colour setting.
|
||||
|
||||
\func{}{wxBitmap}{\param{const char**}{ bits}}
|
||||
|
||||
Creates a bitmap from XPM data.
|
||||
|
||||
\func{}{wxBitmap}{\param{const wxString\& }{name}, \param{long}{ type}}
|
||||
|
||||
Loads a bitmap from a file or resource.
|
||||
|
||||
\func{}{wxBitmap}{\param{const wxImage\&}{ img}, \param{int}{ depth = -1}}
|
||||
|
||||
Creates bitmap object from the image. This has to be done
|
||||
to actually display an image as you cannot draw an image directly on a window.
|
||||
The resulting bitmap will use the provided colour depth (or that of the
|
||||
current system if depth is -1) which entails that a colour reduction has
|
||||
to take place.
|
||||
|
||||
When in 8-bit mode (PseudoColour mode), the GTK port will use a color cube created
|
||||
on program start-up to look up colors. This ensures a very fast conversion, but
|
||||
the image quality won't be perfect (and could be better for photo images using more
|
||||
sophisticated dithering algorithms).
|
||||
|
||||
On Windows, if there is a palette present (set with SetPalette), it will be used when
|
||||
creating the wxBitmap (most useful in 8-bit display mode). On other platforms,
|
||||
the palette is currently ignored.
|
||||
|
||||
\wxheading{Parameters}
|
||||
|
||||
\docparam{bits}{Specifies an array of pixel values.}
|
||||
|
||||
\docparam{width}{Specifies the width of the bitmap.}
|
||||
|
||||
\docparam{height}{Specifies the height of the bitmap.}
|
||||
|
||||
\docparam{depth}{Specifies the depth of the bitmap. If this is omitted, the display depth of the
|
||||
screen is used.}
|
||||
|
||||
\docparam{name}{This can refer to a resource name under MS Windows, or a filename under MS Windows and X.
|
||||
Its meaning is determined by the {\it type} parameter.}
|
||||
|
||||
\docparam{type}{May be one of the following:
|
||||
|
||||
\twocolwidtha{5cm}
|
||||
\begin{twocollist}
|
||||
\twocolitem{\indexit{wxBITMAP\_TYPE\_BMP}}{Load a Windows bitmap file.}
|
||||
\twocolitem{\indexit{wxBITMAP\_TYPE\_BMP\_RESOURCE}}{Load a Windows bitmap from the resource database.}
|
||||
\twocolitem{\indexit{wxBITMAP\_TYPE\_GIF}}{Load a GIF bitmap file.}
|
||||
\twocolitem{\indexit{wxBITMAP\_TYPE\_XBM}}{Load an X bitmap file.}
|
||||
\twocolitem{\indexit{wxBITMAP\_TYPE\_XPM}}{Load an XPM bitmap file.}
|
||||
\twocolitem{\indexit{wxBITMAP\_TYPE\_RESOURCE}}{Load a Windows resource name.}
|
||||
\end{twocollist}
|
||||
|
||||
The validity of these flags depends on the platform and wxWindows configuration.
|
||||
If all possible wxWindows settings are used, the Windows platform supports BMP file, BMP resource,
|
||||
XPM data, and XPM. Under wxGTK, the available formats are BMP file, XPM data, XPM file, and PNG file.
|
||||
Under wxMotif, the available formats are XBM data, XBM file, XPM data, XPM file.
|
||||
|
||||
In addition, wxBitmap can read all formats that \helpref{wxImage}{wximage} can, which currently include
|
||||
wxBITMAP\_TYPE\_JPEG, wxBITMAP\_TYPE\_TIF, wxBITMAP\_TYPE\_PNG, wxBITMAP\_TYPE\_GIF, wxBITMAP\_TYPE\_PCX,
|
||||
and wxBITMAP\_TYPE\_PNM. Of course, you must have wxImage handlers loaded. }
|
||||
|
||||
\docparam{img}{Platform-independent wxImage object.}
|
||||
|
||||
\wxheading{Remarks}
|
||||
|
||||
The first form constructs a bitmap object with no data; an assignment or another member function such as Create
|
||||
or LoadFile must be called subsequently.
|
||||
|
||||
The second and third forms provide copy constructors. Note that these do not copy the
|
||||
bitmap data, but instead a pointer to the data, keeping a reference count. They are therefore
|
||||
very efficient operations.
|
||||
|
||||
The fourth form constructs a bitmap from data whose type and value depends on
|
||||
the value of the {\it type} argument.
|
||||
|
||||
The fifth form constructs a (usually monochrome) bitmap from an array of pixel values, under both
|
||||
X and Windows.
|
||||
|
||||
The sixth form constructs a new bitmap.
|
||||
|
||||
The seventh form constructs a bitmap from pixmap (XPM) data, if wxWindows has been configured
|
||||
to incorporate this feature.
|
||||
|
||||
To use this constructor, you must first include an XPM file. For
|
||||
example, assuming that the file {\tt mybitmap.xpm} contains an XPM array
|
||||
of character pointers called mybitmap:
|
||||
|
||||
\begin{verbatim}
|
||||
#include "mybitmap.xpm"
|
||||
|
||||
...
|
||||
|
||||
wxBitmap *bitmap = new wxBitmap(mybitmap);
|
||||
\end{verbatim}
|
||||
|
||||
The eighth form constructs a bitmap from a file or resource. {\it name} can refer
|
||||
to a resource name under MS Windows, or a filename under MS Windows and X.
|
||||
|
||||
Under Windows, {\it type} defaults to wxBITMAP\_TYPE\_BMP\_RESOURCE.
|
||||
Under X, {\it type} defaults to wxBITMAP\_TYPE\_XPM.

\membersection{wxBitmap::\destruct{wxBitmap}}
|
||||
|
||||
\func{}{\destruct{wxBitmap}}{\void}
|
||||
|
||||
Destroys the wxBitmap object and possibly the underlying bitmap data.
|
||||
Because reference counting is used, the bitmap may not actually be
|
||||
destroyed at this point - only when the reference count is zero will the
|
||||
data be deleted.
|
||||
|
||||
If the application omits to delete the bitmap explicitly, the bitmap will be
|
||||
destroyed automatically by wxWindows when the application exits.
|
||||
|
||||
Do not delete a bitmap that is selected into a memory device context.

\section{What is wxWindows?}
|
||||
|
||||
wxWindows is a C++ framework providing GUI (Graphical User
|
||||
Interface) and other facilities on more than one platform. Version 2 currently
|
||||
supports all desktop versions of MS Windows, Unix with GTK+, Unix with Motif,
|
||||
and MacOS. An OS/2 port is in progress.
|
||||
|
||||
wxWindows was originally developed at the Artificial Intelligence
|
||||
Applications Institute, University of Edinburgh, for internal use,
|
||||
and was first made publicly available in 1992.
|
||||
Version 2 is a vastly improved version written and maintained by
|
||||
Julian Smart, Robert Roebling, Vadim Zeitlin, Vaclav Slavik and many others.
|
||||
|
||||
This manual contains a class reference and topic overviews.
|
||||
For a selection of wxWindows tutorials, please see the documentation page on the \urlref{wxWindows web site}{http://www.wxwindows.org}.
|
||||
|
||||
Please note that in the following, ``MS Windows" often refers to all
|
||||
platforms related to Microsoft Windows, including 16-bit and 32-bit
|
||||
variants, unless otherwise stated. All trademarks are acknowledged.
|
||||
|
||||
\section{Why another cross-platform development tool?}
|
||||
|
||||
wxWindows was developed to provide a cheap and flexible way to maximize
|
||||
investment in GUI application development. While a number of commercial
|
||||
class libraries already existed for cross-platform development,
|
||||
none met all of the following criteria:
|
||||
|
||||
\begin{enumerate}\itemsep=0pt
|
||||
\item low price;
|
||||
\item source availability;
|
||||
\item simplicity of programming;
|
||||
\item support for a wide range of compilers.
|
||||
\end{enumerate}
|
||||
|
||||
Since wxWindows was started, several other free or almost-free
|
||||
GUI frameworks have emerged. However, none has the range of
|
||||
features, flexibility, documentation and the well-established
|
||||
development team that wxWindows has.
|
||||
|
||||
As open source software, wxWindows has benefited from comments,
|
||||
ideas, bug fixes, enhancements and the sheer enthusiasm of
|
||||
users. This gives wxWindows a certain advantage over its
|
||||
commercial competitors (and over free libraries without an
|
||||
independent development team), plus a robustness against the
|
||||
transience of one individual or company. This openness and
|
||||
availability of source code is especially important when the
|
||||
future of thousands of lines of application code may depend upon
|
||||
the longevity of the underlying class library.
|
||||
|
||||
Version 2 goes much further than previous versions in terms of
|
||||
generality and features, allowing applications to be produced
|
||||
that are often indistinguishable from those produced using
|
||||
single-platform toolkits such as Motif, GTK+ and MFC.
|
||||
|
||||
The importance of using a platform-independent class library
|
||||
cannot be overstated, since GUI application development is very
|
||||
time-consuming, and sustained popularity of particular GUIs
|
||||
cannot be guaranteed. Code can very quickly become obsolete if
|
||||
it addresses the wrong platform or audience. wxWindows helps to
|
||||
insulate the programmer from these winds of change. Although
|
||||
wxWindows may not be suitable for every application (such as an
|
||||
OLE-intensive program), it provides access to most of the
|
||||
functionality a GUI program normally requires, plus many extras
|
||||
such as network programming, PostScript output, and HTML
|
||||
rendering; and it can of course be extended as needs dictate.
|
||||
As a bonus, it provides a far cleaner and easier programming
|
||||
interface than the native APIs. Programmers may find it
|
||||
worthwhile to use wxWindows even if they are developing on only
|
||||
one platform.
|
||||
|
||||
It is impossible to sum up the functionality of wxWindows in a few paragraphs, but
|
||||
here are some of the benefits:
|
||||
|
||||
\begin{itemize}\itemsep=0pt
|
||||
\item Low cost (free, in fact!)
|
||||
\item You get the source.
|
||||
\item Available on a variety of popular platforms.
|
||||
\item Works with almost all popular C++ compilers and Python.

|

This chapter describes the practical details of using wxWindows. Please
|
||||
see the file install.txt for up-to-date installation instructions, and
|
||||
changes.txt for differences between versions.
|
||||
|
||||
\section{Include files}
|
||||
|
||||
The main include file is {\tt "wx/wx.h"}; this includes the most commonly
|
||||
used modules of wxWindows.
|
||||
|
||||
To save on compilation time, include only those header files relevant to the
|
||||
source file. If you are using precompiled headers, you should include
|
||||
the following section before any other includes:
|
||||
|
||||
\begin{verbatim}
|
||||
// For compilers that support precompilation, includes "wx.h".
|
||||
#include <wx/wxprec.h>
|
||||
|
||||
#ifdef __BORLANDC__
|
||||
#pragma hdrstop
|
||||
#endif
|
||||
|
||||
#ifndef WX_PRECOMP
|
||||
// Include your minimal set of headers here, or wx.h
|
||||
#include <wx/wx.h>
|
||||
#endif
|
||||
|
||||
... now your other include files ...
|
||||
\end{verbatim}
|
||||
|
||||
The file {\tt "wx/wxprec.h"} includes {\tt "wx/wx.h"}. Although this incantation
|
||||
may seem quirky, it is in fact the end result of a lot of experimentation,
|
||||
and several Windows compilers to use precompilation (those tested are Microsoft Visual C++, Borland C++
|
||||
and Watcom C++).
|
||||
|
||||
Borland precompilation is largely automatic. Visual C++ requires specification of {\tt "wx/wxprec.h"} as
|
||||
the file to use for precompilation. Watcom C++ is automatic apart from the specification of
|
||||
the .pch file. Watcom C++ is strange in requiring the precompiled header to be used only for
|
||||
object files compiled in the same directory as that in which the precompiled header was created.
|
||||
Therefore, the wxWindows Watcom C++ makefiles go through hoops deleting and recreating
|
||||
a single precompiled header file for each module, thus preventing an accumulation of many
|
||||
multi-megabyte .pch files.
|
||||
|
||||
\section{Libraries}
|
||||
|
||||
The GTK and Motif ports of wxWindow can create either a static library or a shared
|
||||
library on most Unix or Unix-like systems. The static library is called libwx\_gtk.a
|
||||
and libwx\_motif.a whereas the name of the shared library is dependent on the
|
||||
system it is created on and the version you are using. The library name for the
|
||||
GTK version of wxWindows 2.2 on Linux and Solaris will be libwx\_gtk-2.2.so.0.0.0,
|
||||
on HP-UX, it will be libwx\_gtk-2.2.sl, on AIX just libwx\_gtk.a etc.
|
||||
|
||||
Under Windows, use the library wx.lib (release) or wxd.lib (debug) for stand-alone Windows
|
||||
applications, or wxdll.lib (wxdlld.lib) for creating DLLs.
|
||||
|
||||
\section{Configuration}
|
||||
|
||||
Options are configurable in the file
|
||||
\rtfsp{\tt "wx/XXX/setup.h"} where XXX is the required platform (such as msw, motif, gtk, mac). Some
|
||||
settings are a matter of taste, some help with platform-specific problems, and
|
||||
others can be set to minimize the size of the library. Please see the setup.h file
|
||||
and {\tt install.txt} files for details on configuration.
|
||||
|
||||
Under Unix (GTK and Motif) the corresponding setup.h files are generated automatically
|
||||
when configuring the wxWindows using the "configure" script. When using the RPM packages
|
||||
for installing wxWindows on Linux, a correct setup.h is shipped in the package and
|
||||
this must not be changed.
|
||||
|
||||
\section{Makefiles}
|
||||
|
||||
At the moment there is no attempt to make Unix makefiles and
|
||||
PC makefiles compatible, i.e. one makefile is required for
|
||||
each environment. The Unix ports use a sophisticated system based
|
||||
on the GNU autoconf tool and this system will create the
|
||||
makefiles as required on the respective platform. Although the
|
||||
makefiles are not identical in Windows, Mac and Unix, care has
|
||||
been taken to make them relatively similar so that moving from
|
||||
one platform to another will be painless.
|
||||
|
||||
Sample makefiles for Unix (suffix .unx), MS C++ (suffix .DOS and .NT), Borland
|
||||
C++ (.BCC and .B32) and Symantec C++ (.SC) are included for the library, demos
|
||||
and utilities.
|
||||
|
||||
The controlling makefile for wxWindows is in the MS-Windows
|
||||
directory {\tt src/msw} for the different Windows compiler and
|
||||
in the build directory when using the Unix ports. The build
|
||||
directory can be chosen by the user. It is the directory in
|
||||
which the "configure" script is run. This can be the normal
|
||||
base directory (by running {\tt ./configure} there) or any other
|
||||
directory (e.g. {\tt ../configure} after creating a build-directory
|
||||
in the directory level above the base directory).
|
||||
|
||||
Please see the platform-specific {\tt install.txt} file for further details.
|
||||
|
||||
\section{Windows-specific files}
|
||||
|
||||
wxWindows application compilation under MS Windows requires at least two
|
||||
extra files, resource and module definition files.
|
||||
|
||||
\subsection{Resource file}\label{resources}
|
||||
|
||||
The least that must be defined in the Windows resource file (extension RC)
|
||||
is the following statement:
|
||||
|
||||
\begin{verbatim}
|
||||
rcinclude "wx/msw/wx.rc"
|
||||
\end{verbatim}
|
||||
|
||||
which includes essential internal wxWindows definitions. The resource script
|
||||
may also contain references to icons, cursors, etc., for example:
|
||||
|
||||
\begin{verbatim}
|
||||
wxicon icon wx.ico
|
||||
\end{verbatim}
|
||||
|
||||
The icon can then be referenced by name when creating a frame icon. See
|
||||
the MS Windows SDK documentation.
|
||||
|
||||
\normalbox{Note: include wx.rc {\it after} any ICON statements
|
||||
so programs that search your executable for icons (such
|
||||
as the Program Manager) find your application icon first.}
|
||||
|
||||
\subsection{Module definition file}
|
||||
|
||||
A module definition file (extension DEF) is required for 16-bit applications, and
|
||||
looks like the following:
|
||||
|
||||
\begin{verbatim}
|
||||
NAME Hello
|
||||
DESCRIPTION 'Hello'
|
||||
EXETYPE WINDOWS
|
||||
STUB 'WINSTUB.EXE'
|
||||
CODE PRELOAD MOVEABLE DISCARDABLE
|
||||
DATA PRELOAD MOVEABLE MULTIPLE
|
||||
HEAPSIZE 1024
|
||||
STACKSIZE 8192
|
||||
\end{verbatim}
|
||||
|
||||
The only lines which will usually have to be changed per application are
|
||||
NAME and DESCRIPTION.
|
||||
|
||||
\section{Allocating and deleting wxWindows objects}
|
||||
|
||||
In general, classes derived from wxWindow must dynamically allocated
|
||||
with {\it new} and deleted with {\it delete}. If you delete a window,
|
||||
all of its children and descendants will be automatically deleted,
|
||||
so you don't need to delete these descendants explicitly.
|
||||
|
||||
When deleting a frame or dialog, use {\bf Destroy} rather than {\bf delete} so
|
||||
that the wxWindows delayed deletion can take effect. This waits until idle time
|
||||
(when all messages have been processed) to actually delete the window, to avoid
|
||||
problems associated with the GUI sending events to deleted windows.
|
||||
|
||||
Don't create a window on the stack, because this will interfere
|
||||
with delayed deletion.
|
||||
|
||||
If you decide to allocate a C++ array of objects (such as wxBitmap) that may
|
||||
be cleaned up by wxWindows, make sure you delete the array explicitly
|
||||
before wxWindows has a chance to do so on exit, since calling {\it delete} on
|
||||
array members will cause memory problems.
|
||||
|
||||
wxColour can be created statically: it is not automatically cleaned
|
||||
up and is unlikely to be shared between other objects; it is lightweight
|
||||
enough for copies to be made.
|
||||
|
||||
Beware of deleting objects such as a wxPen or wxBitmap if they are still in use.
|
||||
Windows is particularly sensitive to this: so make sure you
|
||||
make calls like wxDC::SetPen(wxNullPen) or wxDC::SelectObject(wxNullBitmap) before deleting
|
||||
a drawing object that may be in use. Code that doesn't do this will probably work
|
||||
fine on some platforms, and then fail under Windows.
|
||||
|
||||
\section{Architecture dependency}
|
||||
|
||||
A problem which sometimes arises from writing multi-platform programs is that
|
||||
the basic C types are not defined the same on all platforms. This holds true
|
||||
for both the length in bits of the standard types (such as int and long) as
|
||||
well as their byte order, which might be little endian (typically
|
||||
on Intel computers) or big endian (typically on some Unix workstations). wxWindows
|
||||
defines types and macros that make it easy to write architecture independent
|
||||
code. The types are:
|
||||
|
||||
wxInt32, wxInt16, wxInt8, wxUint32, wxUint16 = wxWord, wxUint8 = wxByte
|
||||
|
||||
where wxInt32 stands for a 32-bit signed integer type etc. You can also check
|
||||
which architecture the program is compiled on using the wxBYTE\_ORDER define
|
||||
which is either wxBIG\_ENDIAN or wxLITTLE\_ENDIAN (in the future maybe wxPDP\_ENDIAN
|
||||
as well).
|
||||
|
||||
The macros handling bit-swapping with respect to the applications endianness
|
||||
are described in the \helpref{Byte order macros}{byteordermacros} section.
|
||||
|
||||
\section{Conditional compilation}
|
||||
|
||||
One of the purposes of wxWindows is to reduce the need for conditional
|
||||
compilation in source code, which can be messy and confusing to follow.
|
||||
However, sometimes it is necessary to incorporate platform-specific
|
||||
features (such as metafile use under MS Windows). The symbols
|
||||
listed in the file {\tt symbols.txt} may be used for this purpose,
|
||||
along with any user-supplied ones.
|
||||
|
||||
\section{C++ issues}
|
||||
|
||||
The following documents some miscellaneous C++ issues.
|
||||
|
||||
\subsection{Templates}
|
||||
|
||||
wxWindows does not use templates since it is a notoriously unportable feature.
|
||||
|
||||
\subsection{RTTI}
|
||||
|
||||
wxWindows does not use run-time type information since wxWindows provides
|
||||
its own run-time type information system, implemented using macros.
|
||||
|
||||
\subsection{Type of NULL}
|
||||
|
||||
Some compilers (e.g. the native IRIX cc) define NULL to be 0L so that
|
||||
no conversion to pointers is allowed. Because of that, all these
|
||||
occurrences of NULL in the GTK port use an explicit conversion such
|
||||
as
|
||||
|
||||
{\small
|
||||
\begin{verbatim}
|
||||
wxWindow *my_window = (wxWindow*) NULL;
|
||||
\end{verbatim}
|
||||
}
|
||||
|
||||
It is recommended to adhere to this in all code using wxWindows as
|
||||
this make the code (a bit) more portable.
|
||||
|
||||
\subsection{Precompiled headers}
|
||||
|
||||
Some compilers, such as Borland C++ and Microsoft C++, support
|
||||
precompiled headers. This can save a great deal of compiling time. The
|
||||
recommended approach is to precompile {\tt "wx.h"}, using this
|
||||
precompiled header for compiling both wxWindows itself and any
|
||||
wxWindows applications. For Windows compilers, two dummy source files
|
||||
are provided (one for normal applications and one for creating DLLs)
|
||||
to allow initial creation of the precompiled header.
|
||||
|
||||
However, there are several downsides to using precompiled headers. One
|
||||
is that to take advantage of the facility, you often need to include
|
||||
more header files than would normally be the case. This means that
|
||||
changing a header file will cause more recompilations (in the case of
|
||||
wxWindows, everything needs to be recompiled since everything includes {\tt "wx.h"}!)
|
||||
|
||||
A related problem is that for compilers that don't have precompiled
|
||||
headers, including a lot of header files slows down compilation
|
||||
considerably. For this reason, you will find (in the common
|
||||
X and Windows parts of the library) conditional
|
||||
compilation that under Unix, includes a minimal set of headers;
|
||||
and when using Visual C++, includes {\tt wx.h}. This should help provide
|
||||
the optimal compilation for each compiler, although it is
|
||||
biased towards the precompiled headers facility available
|
||||
in Microsoft C++.
|
||||
|
||||
\section{File handling}
|
||||
|
||||
When building an application which may be used under different
|
||||
environments, one difficulty is coping with documents which may be
|
||||
moved to different directories on other machines. Saving a file which
|
||||
has pointers to full pathnames is going to be inherently unportable. One
|
||||
approach is to store filenames on their own, with no directory
|
||||
information. The application searches through a number of locally
|
||||
defined directories to find the file. To support this, the class {\bf
|
||||
wxPathList} makes adding directories and searching for files easy, and
|
||||
the global function {\bf wxFileNameFromPath} allows the application to
|
||||
strip off the filename from the path if the filename must be stored.
|
||||
This has undesirable ramifications for people who have documents of the
|
||||
same name in different directories.
|
||||
|
||||
As regards the limitations of DOS 8+3 single-case filenames versus
|
||||
unrestricted Unix filenames, the best solution is to use DOS filenames
|
||||
for your application, and also for document filenames {\it if} the user
|
||||
is likely to be switching platforms regularly. Obviously this latter
|
||||
choice is up to the application user to decide. Some programs (such as
|
||||
YACC and LEX) generate filenames incompatible with DOS; the best
|
||||
solution here is to have your Unix makefile rename the generated files
|
||||
to something more compatible before transferring the source to DOS.
|
||||
Transferring DOS files to Unix is no problem, of course, apart from EOL
|
||||
conversion for which there should be a utility available (such as
|
||||
dos2unix).
|
||||
|
||||
See also the File Functions section of the reference manual for
|
||||
descriptions of miscellaneous file handling functions.
|
||||

\setfooter{\thepage}{}{}{}{}{\thepage}%
|

|

In addition to the core wxWindows library, a number of further
|
||||
libraries and utilities are supplied with each distribution.
|
||||
|
||||
Some are under the 'contrib' hierarchy which mirrors the
|
||||
structure of the main wxWindows hierarchy. See also the 'utils'
|
||||
hierarchy. The first place to look for documentation about
|
||||
these tools and libraries is under the wxWindows 'docs' hierarchy,

\item[{\bf Helpview}]
|
||||
Helpview is a program for displaying wxWindows HTML
|
||||
Help files. In many cases, you may wish to use the wxWindows HTML
|
||||
Help classes from within your application, but this provides a
|
||||
handy stand-alone viewer. See \helpref{wxHTML Notes}{wxhtml} for more details.
|
||||
You can find it in {\tt samples/html/helpview}.

|

This chapter is intended to list strategies that may be useful when
|
||||
writing and debugging wxWindows programs. If you have any good tips,
|
||||
please submit them for inclusion here.
|
||||
|
||||
\section{Strategies for reducing programming errors}
|
||||
|
||||
\subsection{Use ASSERT}
|
||||
|
||||
Although I haven't done this myself within wxWindows, it is good
|
||||
practice to use ASSERT statements liberally, that check for conditions that
|
||||
should or should not hold, and print out appropriate error messages.
|
||||
These can be compiled out of a non-debugging version of wxWindows
|
||||
and your application. Using ASSERT is an example of `defensive programming':
|
||||
it can alert you to problems later on.
|
||||
|
||||
\subsection{Use wxString in preference to character arrays}
|
||||
|
||||
Using wxString can be much safer and more convenient than using char *.
|
||||
Again, I haven't practiced what I'm preaching, but I'm now trying to use
|
||||
wxString wherever possible. You can reduce the possibility of memory
|
||||
leaks substantially, and it is much more convenient to use the overloaded
|
||||
operators than functions such as strcmp. wxString won't add a significant
|
||||
overhead to your program; the overhead is compensated for by easier
|
||||
manipulation (which means less code).
|
||||
|
||||
The same goes for other data types: use classes wherever possible.
|
||||
|
||||
\section{Strategies for portability}
|
||||
|
||||
\subsection{Use relative positioning or constraints}
|
||||
|
||||
Don't use absolute panel item positioning if you can avoid it. Different GUIs have
|
||||
very differently sized panel items. Consider using the constraint system, although this
|
||||
can be complex to program.
|
||||
|
||||
Alternatively, you could use alternative .wrc (wxWindows resource files) on different
|
||||
platforms, with slightly different dimensions in each. Or space your panel items out
|
||||
to avoid problems.
|
||||
|
||||
\subsection{Use wxWindows resource files}
|
||||
|
||||
Use .wrc (wxWindows resource files) where possible, because they can be easily changed
|
||||
independently of source code. Bitmap resources can be set up to load different
|
||||
kinds of bitmap depending on platform (see the section on resource files).
|
||||
|
||||
\section{Strategies for debugging}\label{debugstrategies}
|
||||
|
||||
\subsection{Positive thinking}
|
||||
|
||||
It is common to blow up the problem in one's imagination, so that it seems to threaten
|
||||
weeks, months or even years of work. The problem you face may seem insurmountable:
|
||||
but almost never is. Once you have been programming for some time, you will be able
|
||||
to remember similar incidents that threw you into the depths of despair. But
|
||||
remember, you always solved the problem, somehow!
|
||||
|
||||
Perseverance is often the key, even though a seemingly trivial problem
|
||||
can take an apparently inordinate amount of time to solve. In the end,
|
||||
you will probably wonder why you worried so much. That's not to say it
|
||||
isn't painful at the time. Try not to worry -- there are many more important
|
||||
things in life.
|
||||
|
||||
\subsection{Simplify the problem}
|
||||
|
||||
Reduce the code exhibiting the problem to the smallest program possible
|
||||
that exhibits the problem. If it is not possible to reduce a large and
|
||||
complex program to a very small program, then try to ensure your code
|
||||
doesn't hide the problem (you may have attempted to minimize the problem
|
||||
in some way: but now you want to expose it).
|
||||
|
||||
With luck, you can add a small amount of code that causes the program
|
||||
to go from functioning to non-functioning state. This should give a clue
|
||||
to the problem. In some cases though, such as memory leaks or wrong
|
||||
deallocation, this can still give totally spurious results!
|
||||
|
||||
\subsection{Use a debugger}
|
||||
|
||||
This sounds like facetious advice, but it is surprising how often people
|
||||
don't use a debugger. Often it is an overhead to install or learn how to
|
||||
use a debugger, but it really is essential for anything but the most
|
||||
trivial programs.
|
||||
|
||||
\subsection{Use logging functions}
|
||||
|
||||
There is a variety of logging functions that you can use in your program:
|
||||
see \helpref{Logging functions}{logfunctions}.
|
||||
|
||||
Using tracing statements may be more convenient than using the debugger
|
||||
in some circumstances (such as when your debugger doesn't support a lot
|
||||
of debugging code, or you wish to print a bunch of variables).
|
||||
|
||||
\subsection{Use the wxWindows debugging facilities}
|
||||
|
||||
You can use wxDebugContext to check for
|
||||
memory leaks and corrupt memory: in fact in debugging mode, wxWindows will
|
||||
automatically check for memory leaks at the end of the program if wxWindows is suitably
|
||||
configured. Depending on the operating system and compiler, more or less
|
||||
specific information about the problem will be logged.
|
||||
|
||||
You should also use \helpref{debug macros}{debugmacros} as part of a `defensive programming' strategy,
|
||||
scattering wxASSERTs liberally to test for problems in your code as early as possible. Forward thinking
|
||||
will save a surprising amount of time in the long run.
|
||||
|
||||
See the \helpref{debugging overview}{debuggingoverview} for further information.
|
||||
|
||||
\subsection{Check Windows debug messages}
|
||||
|
||||
Under Windows, it is worth running your program with
|
||||
\urlref{DbgView}{http://www.sysinternals.com} running or
|
||||
some other program that shows Windows-generated debug messages. It is
|
||||
possible it will show invalid handles being used. You may have fun seeing
|
||||
what commercial programs cause these normally hidden errors! Microsoft
|
||||
recommend using the debugging version of Windows, which shows up even
|
||||
more problems. However, I doubt it is worth the hassle for most
|
||||
applications. wxWindows is designed to minimize the possibility of such
|
||||
errors, but they can still happen occasionally, slipping through unnoticed
|
||||
because they are not severe enough to cause a crash.
|
||||
|
||||
\subsection{Genetic mutation}
|
||||
|
||||
If we had sophisticated genetic algorithm tools that could be applied
|
||||
to programming, we could use them. Until then, a common -- if rather irrational --
|
||||
technique is to just make arbitrary changes to the code until something
|
||||
different happens. You may have an intuition why a change will make a difference;
|
||||
otherwise, just try altering the order of code, comment lines out, anything
|
||||
to get over an impasse. Obviously, this is usually a last resort.

\wxheading{Remarks}
|
||||
|
||||
On a monochrome display, wxWindows shows
|
||||
all brushes as white unless the colour is really black.
|
||||
|
||||
Do not initialize objects on the stack before the program commences,
|
||||
since other required structures may not have been set up yet. Instead,
|
||||
define global pointers to objects and create them in \helpref{wxApp::OnInit}{wxapponinit} or
|
||||
when required.
|
||||
|
||||
An application may wish to create brushes with different
|
||||
characteristics dynamically, and there is the consequent danger that a
|
||||
large number of duplicate brushes will be created. Therefore an
|
||||
application may wish to get a pointer to a brush by using the global
|
||||
list of brushes {\bf wxTheBrushList}, and calling the member function
|
||||
\rtfsp{\bf FindOrCreateBrush}.
|
||||
|
||||
wxBrush uses a reference counting system, so assignments between brushes are very
|
||||
cheap. You can therefore use actual wxBrush objects instead of pointers without
|
||||
efficiency problems. Once one wxBrush object changes its data it will create its
|
||||
own brush data internally so that other brushes, which previously shared the
|
||||
data using the reference counting, are not affected.

The destructor may not delete the underlying brush object of the native windowing

system, since wxBrush uses a reference counting system for efficiency.
|

|

Although all remaining brushes are deleted when the application exits,
|
||||
the application should try to clean up all brushes itself. This is because
|
||||
wxWindows cannot know if a pointer to the brush object is stored in an
|

application data structure, and there is a risk of double deletion.

The style will be set to wxSTIPPLE, unless the bitmap has a mask associated

to it, in which case the style will be set to wxSTIPPLE\_MASK\_OPAQUE.
|

|
||||
If the wxSTIPPLE variant is used, the bitmap will be used to fill out the
|
||||
area to be drawn. If the wxSTIPPLE\_MASK\_OPAQUE is used, the current
|
||||
text foreground and text background determine what colours are used for
|
||||
displaying and the bits in the mask (which is a mono-bitmap actually)
|
||||
determine where to draw what.
|
||||
|

Note that under Windows 95, only 8x8 pixel large stipple bitmaps are

supported, Windows 98 and NT as well as GTK support arbitrary bitmaps.

\wxheading{Remarks}
|
||||
|
||||
There is only one instance of this class: {\bf wxTheBrushList}. Use
|
||||
this object to search for a previously created brush of the desired
|
||||
type and create it if not already found. In some windowing systems,
|
||||
the brush may be a scarce resource, so it can pay to reuse old
|
||||
resources if possible. When an application finishes, all brushes will
|
||||
be deleted and their resources freed, eliminating the possibility of
|
||||
`memory leaks'. However, it is best not to rely on this automatic
|
||||
cleanup because it can lead to double deletion in some circumstances.
|
||||
|
||||
There are two mechanisms in recent versions of wxWindows which make the
|
||||
brush list less useful than it once was. Under Windows, scarce resources
|
||||
are cleaned up internally if they are not being used. Also, a referencing
|
||||
counting mechanism applied to all GDI objects means that some sharing
|
||||
of underlying resources is possible. You don't have to keep track of pointers,
|
||||
working out when it is safe delete a brush, because the referencing counting does
|
||||
it for you. For example, you can set a brush in a device context, and then
|
||||
immediately delete the brush you passed, because the brush is `copied'.
|
||||
|
||||
So you may find it easier to ignore the brush list, and instead create
|
||||
and copy brushes as you see fit. If your Windows resource meter suggests
|
||||
your application is using too many resources, you can resort to using
|
||||
GDI lists to share objects explicitly.
|
||||
|
||||
The only compelling use for the brush list is for wxWindows to keep
|
||||
track of brushes in order to clean them up on exit. It is also kept for
|
||||
backward compatibility with earlier versions of wxWindows.

Just create a wxBusyInfo object on the stack, and within the current scope,

a message window will be shown.

You may also want to call wxTheApp->Yield() to refresh the window

periodically (in case it had been obscured by other windows, for

example) like this:

wxTheApp->Yield();

but take care to not cause undesirable reentrancies when doing it (see

|
||||
Note that under Motif, calling this function immediately after

||||
creation of a button and before the creation of other buttons
|
||||
will cause misalignment of the row of buttons, since default
|
||||
buttons are larger. To get around this, call {\it SetDefault}\rtfsp

after you have created a row of buttons: wxWindows will

then set the size of all buttons currently on the panel to

the same size.

|

|
||||
The calendar control allows the user to pick a date interactively. For this,
|
||||
it displays a window containing several parts: the control to pick the month
|
||||
and the year at the top (either or both of them may be disabled) and a month
|
||||
area below them which shows all the days in the month. The user can move the
|
||||
current selection using the keyboard and select the date (generating
|
||||
{\tt EVT\_CALENDAR} event) by pressing {\tt <Return>} or double clicking it.
|
||||
|
||||
It has advanced possibilities for the customization of its display. All global
|
||||
settings (such as colours and fonts used) can, of course, be changed. But
|
||||
also, the display style for each day in the month can be set independently
|
||||
using \helpref{wxCalendarDateAttr}{wxcalendardateattr} class.
|
||||
|
||||
An item without custom attributes is drawn with the default colours and
|
||||
font and without border, but setting custom attributes with
|
||||
\helpref{SetAttr}{wxcalendarctrlsetattr} allows to modify its appearance. Just
|
||||
create a custom attribute object and set it for the day you want to be
|
||||
displayed specially (note that the control will take ownership of the pointer,
|
||||
i.e. it will delete it itself). A day may be marked as being a holiday, even
|
||||
if it is not recognized as one by \helpref{wxDateTime}{tdateholidays} using
|
||||
\helpref{SetHoliday}{wxcalendardateattrsetholiday} method.
|
||||
|
||||
As the attributes are specified for each day, they may change when the month
|
||||
is changed, so you will often want to update them in
|
||||
{\tt EVT\_CALENDAR\_MONTH} event handler.

\section{\class{wxCaret}}\label{wxcaret}
|
||||
|
||||
A caret is a blinking cursor showing the position where the typed text will
|
||||
appear. The text controls usually have a caret but wxCaret class also allows
|
||||
to use a caret in other windows.
|
||||
|
||||
Currently, the caret appears as a rectangle of the given size. In the future,
|
||||
it will be possible to specify a bitmap to be used for the caret shape.
|
||||
|
||||
A caret is always associated with a window and the current caret can be
|
||||
retrieved using \helpref{wxWindow::GetCaret}{wxwindowgetcaret}. The same caret
|
||||
can't be reused in two different windows.

|
||||
Returns the blink time which is measured in milliseconds and is the time elapsed
|
||||
between 2 inversions of the caret (blink time of the caret is the same
|
||||
for all carets, so this functions is static).

|
||||
\constfunc{bool}{IsVisible}{\void}
|
||||
|
||||
Returns TRUE if the caret is visible and FALSE if it is permanently
|
||||
hidden (if it is is blinking and not shown currently but will be after the
|

other is based on so-called constraints and is deprecated, though still available.

\section{\class{wxClientData}}\label{wxclientdata}
|
||||
|
||||
All classes deriving from \helpref{wxEvtHandler}{wxevthandler}
|
||||
(such as all controls and \helpref{wxApp}{wxapp})
|
||||
can hold arbitrary data which is here referred to as "client data".
|
||||
This is useful e.g. for scripting languages which need to handle
|
||||
shadow objects for most of wxWindows' classes and which store
|
||||
a handle to such a shadow class as client data in that class.
|
||||
This data can either be of type void - in which case the data
|
||||
{\it container} does not take care of freeing the data again
|
||||
or it is of type wxClientData or its derivates. In that case the
|
||||
container (e.g. a control) will free the memory itself later.
|
||||
Note that you {\it must not} assign both void data and data
|
||||
derived from the wxClientData class to a container.
|
||||
|
||||
Some controls can hold various items and these controls can
|
||||
additionally hold client data for each item. This is the case for
|
||||
\helpref{wxChoice}{wxchoice}, \helpref{wxComboBox}{wxcombobox}
|
||||
and \helpref{wxListBox}{wxlistbox}. \helpref{wxTreeCtrl}{wxtreectrl}
|
||||
has a specialized class \helpref{wxTreeItemData}{wxtreeitemdata}
|
||||
for each item in the tree.
|
||||
|
||||
If you want to add client data to your own classes, you may
|
||||
use the mix-in class \helpref{wxClientDataContainer}{wxclientdatacontainer}.

This class is a mixin that provides storage and management of "client

data." This data can either be of type void - in which case the data

\section{\class{wxClipboard}}\label{wxclipboard}
|
||||
|
||||
A class for manipulating the clipboard. Note that this is not compatible with the
|
||||
clipboard class from wxWindows 1.xx, which has the same name but a different implementation.
|
||||
|
||||
To use the clipboard, you call member functions of the global {\bf wxTheClipboard} object.
|
||||
|
||||
See also the \helpref{wxDataObject overview}{wxdataobjectoverview} for further information.
|
||||
|
||||
Call \helpref{wxClipboard::Open}{wxclipboardopen} to get ownership of the clipboard. If this operation returns TRUE, you
|
||||
now own the clipboard. Call \helpref{wxClipboard::SetData}{wxclipboardsetdata} to put data
|
||||
on the clipboard, or \helpref{wxClipboard::GetData}{wxclipboardgetdata} to
|
||||
retrieve data from the clipboard. Call \helpref{wxClipboard::Close}{wxclipboardclose} to close
|
||||
the clipboard and relinquish ownership. You should keep the clipboard open only momentarily.
|
||||
|
||||
For example:
|
||||
|
||||
\begin{verbatim}
|
||||
// Write some text to the clipboard
|
||||
if (wxTheClipboard->Open())
|
||||
{
|
||||
// This data objects are held by the clipboard,
|
||||
// so do not delete them in the app.
|
||||
wxTheClipboard->SetData( new wxTextDataObject("Some text") );
|
||||
wxTheClipboard->Close();
|
||||

\section{\class{wxCloseEvent}}\label{wxcloseevent}
|
||||
|
||||
This event class contains information about window and session close events.
|
||||
|
||||
The handler function for EVT\_CLOSE is called when the user has tried to close a a frame
|
||||
or dialog box using the window manager (X) or system menu (Windows). It can
|
||||
also be invoked by the application itself programmatically, for example by
|
||||
calling the \helpref{wxWindow::Close}{wxwindowclose} function.
|
||||
|
||||
You should check whether the application is forcing the deletion of the window
|
||||
using \helpref{wxCloseEvent::CanVeto}{wxcloseeventcanveto}. If this is {\tt FALSE},
|
||||
you {\it must} destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
|
||||
If the return value is TRUE, it is up to you whether you respond by destroying the window.
|
||||
|
||||
If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to
|
||||
let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function
|
||||
to return {\tt TRUE} or {\tt FALSE} depending on whether the close instruction was honoured or not.

\section{\class{wxCmdLineParser}}\label{wxcmdlineparser}
|
||||
|
||||
wxCmdLineParser is a class for parsing command line.
|
||||
|
||||
It has the following features:
|
||||
|
||||
\begin{enumerate}\itemsep=0pt
|
||||
\item distinguishes options, switches and parameters; allows option grouping
|
||||
\item allows both short and long options
|
||||
\item automatically generates the usage message from the command line description
|
||||
\item does type checks on the options values (number, date, $\ldots$).
|
||||
\end{enumerate}
|
||||
|
||||
To use it you should follow these steps:
|
||||
|
||||
\begin{enumerate}\itemsep=0pt
|
||||
\item \helpref{construct}{wxcmdlineparserconstruction} an object of this class
|
||||
giving it the command line to parse and optionally its description or use
|
||||
{\tt AddXXX()} functions later
|
||||
\item call {\tt Parse()}
|
||||
\item use {\tt Found()} to retrieve the results
|
||||
\end{enumerate}
|
||||
|
||||
In the documentation below the following terminology is used:
|
||||
|
||||
\begin{twocollist}\itemsep=0pt
|
||||
\twocolitem{switch}{This is a boolean option which can be given or not, but
|
||||
which doesn't have any value. We use the word switch to distinguish such boolean
|
||||
options from more generic options like those described below. For example,
|
||||
{\tt -v} might be a switch meaning "enable verbose mode".}
|
||||
\twocolitem{option}{Option for us here is something which comes with a value 0
|
||||
unlike a switch. For example, {\tt -o:filename} might be an option which allows
|
||||
to specify the name of the output file.}
|
||||
\twocolitem{parameter}{This is a required program argument.}
|
||||
\end{twocollist}

||||

||||
|
||||
\wxheading{Constants}
|
||||
|
||||
The structure wxCmdLineEntryDesc is used to describe the one command
|
||||
line switch, option or parameter. An array of such structures should be passed
|
||||
to \helpref{SetDesc()}{wxcmdlineparsersetdesc}. Also, the meanings of parameters
|
||||
of the {\tt AddXXX()} functions are the same as of the corresponding fields in
|
||||
this structure:
|
||||
|
||||
\begin{verbatim}
|
||||
struct wxCmdLineEntryDesc
|
||||
{
|
||||
wxCmdLineEntryType kind;
|
||||
const wxChar *shortName;
|
||||
const wxChar *longName;
|
||||
const wxChar *description;
|
||||
wxCmdLineParamType type;
|
||||
int flags;
|
||||
};
|
||||
\end{verbatim}
|
||||
|
||||
The type of a command line entity is in the {\tt kind} field and may be one of
|
||||
the following constants:
|
||||
|
||||
{\small%
|
||||
\begin{verbatim}
|
||||
enum wxCmdLineEntryType
|
||||
{
|
||||
wxCMD_LINE_SWITCH,
|
||||
wxCMD_LINE_OPTION,
|
||||
wxCMD_LINE_PARAM,
|
||||
wxCMD_LINE_NONE // use this to terminate the list
|
||||
}
|
||||
\end{verbatim}
|
||||
}
|
||||
|
||||
The field {\tt shortName} is the usual, short, name of the switch or the option.
|
||||
{\tt longName} is the corresponding long name or NULL if the option has no long
|
||||
name. Both of these fields are unused for the parameters. Both the short and
|
||||
long option names can contain only letters, digits and the underscores.
|
||||
|
||||
{\tt description} is used by the \helpref{Usage()}{wxcmdlineparserusage} method
|
||||
to construct a help message explaining the syntax of the program.
|
||||
|
||||
The possible values of {\tt type} which specifies the type of the value accepted
|
||||
by an option or parameter are:
|
||||
|
||||
{\small%
|
||||
\begin{verbatim}
|
||||
enum wxCmdLineParamType
|
||||
{
|
||||
wxCMD_LINE_VAL_STRING, // default
|
||||
wxCMD_LINE_VAL_NUMBER,
|
||||
wxCMD_LINE_VAL_DATE,
|
||||
wxCMD_LINE_VAL_NONE
|
||||
}
|
||||
\end{verbatim}
|
||||
}
|
||||
|
||||
Finally, the {\tt flags} field is a combination of the following bit masks:
|
||||
|
||||
{\small%
|
||||
\begin{verbatim}
|
||||
enum
|
||||
{
|
||||
wxCMD_LINE_OPTION_MANDATORY = 0x01, // this option must be given
|
||||
wxCMD_LINE_PARAM_OPTIONAL = 0x02, // the parameter may be omitted
|
||||
wxCMD_LINE_PARAM_MULTIPLE = 0x04, // the parameter may be repeated
|
||||
wxCMD_LINE_OPTION_HELP = 0x08, // this option is a help request
|
||||
wxCMD_LINE_NEEDS_SEPARATOR = 0x10, // must have sep before the value
|
||||
}
|
||||
\end{verbatim}
|
||||
}
|
||||
|
||||
Notice that by default (i.e. if flags are just $0$), options are optional (sic)
|
||||
and each call to \helpref{AddParam()}{wxcmdlineparseraddparam} allows one more
|
||||
parameter - this may be changed by giving non-default flags to it, i.e. use
|
||||
{\tt wxCMD\_LINE\_OPTION\_MANDATORY} to require that the option is given and
|
||||
{\tt wxCMD\_LINE\_PARAM\_OPTIONAL} to make a parameter optional. Also,
|
||||
{\tt wxCMD\_LINE\_PARAM\_MULTIPLE} may be specified if the programs accepts a
|
||||
variable number of parameters - but it only can be given for the last parameter
|
||||
in the command line description. If you use this flag, you will probably need to
|
||||
use \helpref{GetParamCount}{wxcmdlineparsergetparamcount} to retrieve the number
|
||||
of parameters effectively specified after calling
|
||||
\helpref{Parse}{wxcmdlineparserparse}.
|
||||
|
||||
The last flag {\tt wxCMD\_LINE\_NEEDS\_SEPARATOR} can be specified to require a
|
||||
separator (either a colon, an equal sign or white space) between the option
|
||||
name and its value. By default, no separator is required.

\membersection{Construction}\label{wxcmdlineparserconstruction}
|
||||
|
||||
Before \helpref{Parse}{wxcmdlineparserparse} can be called, the command line
|
||||
parser object must have the command line to parse and also the rules saying
|
||||
which switches, options and parameters are valid - this is called command line
|
||||
description in what follows.
|
||||
|
||||
You have complete freedom of choice as to when specify the required information,
|
||||
the only restriction is that it must be done before calling
|
||||
\helpref{Parse}{wxcmdlineparserparse}.
|
||||
|
||||
To specify the command line to parse you may use either one of constructors
|
||||
accepting it (\helpref{wxCmdLineParser(argc, argv)}{wxcmdlineparserwxcmdlineparserargc} or
|
||||
\helpref{wxCmdLineParser}{wxcmdlineparserwxcmdlineparserdescargc} usually) or,
|
||||
if you use \helpref{the default constructor}{wxcmdlineparserwxcmdlineparserdef},
|
||||
you can do it later by calling
|
||||
\helpref{SetCmdLine}{wxcmdlineparsersetcmdlineargc}.
|
||||
|
||||
The same holds for command line description: it can be specified either in
|
||||
the constructor (\helpref{without command line}{wxcmdlineparserwxcmdlineparserdesc} or
|
||||
\helpref{together with it}{wxcmdlineparserwxcmdlineparserdescargc}) or
|
||||
constructed later using either \helpref{SetDesc}{wxcmdlineparsersetdesc} or
|
||||
combination of \helpref{AddSwitch}{wxcmdlineparseraddswitch},
|
||||
\helpref{AddOption}{wxcmdlineparseraddoption} and
|
||||
\helpref{AddParam}{wxcmdlineparseraddparam} methods.
|
||||
|
||||
Using constructors or \helpref{SetDesc}{wxcmdlineparsersetdesc} uses a (usually
|
||||
{\tt const static}) table containing the command line description. If you want
|
||||
to decide which options to accept during the run-time, using one of the
|
||||
{\tt AddXXX()} functions above might be preferable.
|
||||
|
||||
\membersection{Customization}\label{wxcmdlineparsercustomization}
|
||||
|
||||
wxCmdLineParser has several global options which may be changed by the
|
||||
application. All of the functions described in this section should be called
|
||||
before \helpref{Parse}{wxcmdlineparserparse}.
|
||||
|
||||
First global option is the support for long (also known as GNU-style) options.
|
||||
The long options are the ones which start with two dashes ({\tt "--"}) and look
|
||||
like this: {\tt --verbose}, i.e. they generally are complete words and not some
|
||||
abbreviations of them. As long options are used by more and more applications,
|
||||
they are enabled by default, but may be disabled with
|
||||
\helpref{DisableLongOptions}{wxcmdlineparserdisablelongoptions}.
|
||||
|
||||
Another global option is the set of characters which may be used to start an
|
||||
option (otherwise, the word on the command line is assumed to be a parameter).
|
||||
Under Unix, {\tt '-'} is always used, but Windows has at least two common
|
||||
choices for this: {\tt '-'} and {\tt '/'}. Some programs also use {\tt '+'}.
|
||||
The default is to use what suits most the current platform, but may be changed
|
||||
with \helpref{SetSwitchChars}{wxcmdlineparsersetswitchchars} method.
|
||||
|
||||
Finally, \helpref{SetLogo}{wxcmdlineparsersetlogo} can be used to show some
|
||||
application-specific text before the explanation given by
|
||||
\helpref{Usage}{wxcmdlineparserusage} function.
|
||||
|
||||
\membersection{Parsing command line}\label{wxcmdlineparserparsing}
|
||||
|
||||
After the command line description was constructed and the desired options were
|
||||
set, you can finally call \helpref{Parse}{wxcmdlineparserparse} method.
|
||||
It returns $0$ if the command line was correct and was parsed, $-1$ if the help
|
||||
option was specified (this is a separate case as, normally, the program will
|
||||
terminate after this) or a positive number if there was an error during the
|
||||
command line parsing.
|
||||
|
||||
In the latter case, the appropriate error message and usage information are
|
||||
logged by wxCmdLineParser itself using the standard wxWindows logging functions.
|
||||
|
||||
\membersection{Getting results}\label{wxcmdlineparsergettingresults}
|
||||
|
||||
After calling \helpref{Parse}{wxcmdlineparserparse} (and if it returned $0$),
|
||||
you may access the results of parsing using one of overloaded {\tt Found()}
|
||||
methods.
|
||||
|
||||
For a simple switch, you will simply call
|
||||
\helpref{Found}{wxcmdlineparserfoundswitch} to determine if the switch was given
|
||||
or not, for an option or a parameter, you will call a version of {\tt Found()}
|
||||
which also returns the associated value in the provided variable. All
|
||||
{\tt Found()} functions return TRUE if the switch or option were found in the
|
||||
command line or FALSE if they were not specified.

A colour is an object representing a combination of Red, Green, and Blue (RGB) intensity values,
|
||||
and is used to determine drawing colours. See the
|
||||
entry for \helpref{wxColourDatabase}{wxcolourdatabase} for how a pointer to a predefined,
|

named colour may be returned instead of creating a new colour.
|

Valid RGB values are in the range 0 to 255.

A combobox is like a combination of an edit control and a listbox. It can be
|
||||
displayed as static list with editable or read-only text field; or a drop-down list with
|
||||
text field; or a drop-down list without a text field.
|
||||
|
||||
A combobox permits a single selection only. Combobox items are numbered from zero.

Constructor. wxCommand is an abstract class, so you will need to derive

a new class and call this constructor from your own constructor.
|
||||
|
||||
{\it canUndo} tells the command processor whether this command is undo-able. You
|
||||
can achieve the same functionality by overriding the CanUndo member function (if for example
|
||||
the criteria for undoability is context-dependent).

{\it name} must be supplied for the command processor to display the command name

in the application's edit menu.

Return TRUE to indicate that the action has taken place, FALSE otherwise.
|

Returning FALSE will indicate to the command processor that the action is
|
||||
not undoable and should not be added to the command history.
|
||||
|

\membersection{wxCommand::GetName}
|

\func{bool}{Undo}{\void}
|

|
||||
Override this member function to un-execute a previous Do.
|
||||
Return TRUE to indicate that the action has taken place, FALSE otherwise.
|
||||
Returning FALSE will indicate to the command processor that the action is
|
||||
not redoable and no change should be made to the command history.
|
||||
|
||||
How you implement this command is totally application dependent, but typical
|
||||
strategies include:
|
||||
|
||||
\begin{itemize}\itemsep=0pt
|
||||
\item Perform an inverse operation on the last modified piece of
|
||||
data in the document. When redone, a copy of data stored in command
|
||||
is pasted back or some operation reapplied. This relies on the fact that
|
||||
you know the ordering of Undos; the user can never Undo at an arbitrary position
|
||||
in the command history.
|
||||
\item Restore the entire document state (perhaps using document transactioning).
|
||||
Potentially very inefficient, but possibly easier to code if the user interface
|
||||
and data are complex, and an `inverse execute' operation is hard to write.
|
||||
\end{itemize}
|
||||
|
||||
The docview sample uses the first method, to remove or restore segments

||||
in the drawing.

\section{\class{wxCondition}}\label{wxcondition}
|
||||
|
||||
wxCondition variables correspond to pthread conditions or to Win32 event
|
||||
objects. They may be used in a multithreaded application to wait until the
|
||||
given condition becomes true which happens when the condition becomes signaled.
|
||||
|
||||
For example, if a worker thread is doing some long task and another thread has
|
||||
to wait until it is finished, the latter thread will wait on the condition
|
||||
object and the worker thread will signal it on exit (this example is not
|
||||
perfect because in this particular case it would be much better to just
|
||||
\helpref{Wait()}{wxthreadwait} for the worker thread, but if there are several
|
||||
worker threads it already makes much more sense).
|
||||
|
||||
Note that a call to \helpref{Signal()}{wxconditionsignal} may happen before the
|
||||
other thread calls \helpref{Wait()}{wxconditionwait} and, just as with the
|
||||
pthread conditions, the signal is then lost and so if you want to be sure to
|
||||
get it you must use a mutex together with the condition variable.
|
||||
|
||||
\wxheading{Example}
|
||||
|
||||
This example shows how a main thread may launch a worker thread which starts
|
||||
running and then waits until the main thread signals it to continue:
|
||||
|
||||
\begin{verbatim}
|
||||
class MySignallingThread : public wxThread
|
||||
{
|
||||
public:
|
||||
MySignallingThread(wxMutex *mutex, wxCondition *condition)
|
||||
{
|
||||
m_mutex = mutex;
|
||||
m_condition = condition;
|
||||
|
||||
Create();
|
||||
}
|
||||
|
||||
virtual ExitCode Entry()
|
||||
{
|
||||
... do our job ...
|
||||
|
||||
// tell the other(s) thread(s) that we're about to terminate: we must
|
||||
// lock the mutex first or we might signal the condition before the
|
||||
// waiting threads start waiting on it!
|
||||
wxMutexLocker lock(m_mutex);
|
||||
m_condition.Broadcast(); // same as Signal() here -- one waiter only
|
||||
|
||||
return 0;
|
||||
}
|
||||
|
||||
private:
|
||||
wxCondition *m_condition;
|
||||
wxMutex *m_mutex;
|
||||
};
|
||||
|
||||
int main()
|
||||
{
|
||||
wxMutex mutex;
|
||||
wxCondition condition(mutex);
|
||||
|
||||
// the mutex should be initially locked
|
||||
mutex.Lock();
|
||||
|
||||
// create and run the thread but notice that it won't be able to
|
||||
// exit (and signal its exit) before we unlock the mutex below
|
||||
MySignallingThread *thread = new MySignallingThread(&mutex, &condition);
|
||||
|
||||
thread->Run();
|
||||
|
||||
// wait for the thread termination: Wait() atomically unlocks the mutex
|
||||
// which allows the thread to continue and starts waiting
|
||||
condition.Wait();
|
||||
|
||||
// now we can exit
|
||||
return 0;
|
||||
}
|
||||
\end{verbatim}
|
||||
|
||||
Of course, here it would be much better to simply use a joinable thread and
|
||||
call \helpref{wxThread::Wait}{wxthreadwait} on it, but this example does
|
||||
illustrate the importance of properly locking the mutex when using
|

wxCondition.

\section{\class{wxConfigBase}}\label{wxconfigbase}
|
||||
|
||||
wxConfigBase class defines the basic interface of all config classes. It can
|
||||
not be used by itself (it is an abstract base class) and you will always use one
|
||||
of its derivations: wxIniConfig, wxFileConfig, wxRegConfig or any other.
|
||||
|
||||
However, usually you don't even need to know the precise nature of the class
|
||||
you're working with but you would just use the wxConfigBase methods. This
|
||||
allows you to write the same code regardless of whether you're working with
|
||||
the registry under Win32 or text-based config files under Unix (or even
|
||||
Windows 3.1 .INI files if you're really unlucky). To make writing the portable
|
||||
code even easier, wxWindows provides a typedef wxConfig
|
||||
which is mapped onto the native wxConfigBase implementation on the given
|
||||
platform: i.e. wxRegConfig under Win32, wxIniConfig under Win16 and
|
||||
wxFileConfig otherwise.
|
||||
|

features of this class.

\wxheading{Example}
|
||||
|
||||
Here is how you would typically use this class:
|
||||
|
||||
\begin{verbatim}
|
||||
// using wxConfig instead of writing wxFileConfig or wxRegConfig enhances
|
||||
// portability of the code
|
||||
wxConfig *config = new wxConfig("MyAppName");
|
||||
|
||||
wxString str;
|
||||
if ( config->Read("LastPrompt", &str) ) {
|
||||
// last prompt was found in the config file/registry and its value is now
|
||||
// in str
|
||||
...
|
||||
}
|
||||
else {
|
||||
// no last prompt...
|
||||
}
|
||||
|
||||
// another example: using default values and the full path instead of just
|
||||
// key name: if the key is not found , the value 17 is returned
|
||||
long value = config->Read("/LastRun/CalculatedValues/MaxValue", 17);
|
||||
...
|
||||
...
|
||||
...
|
||||
// at the end of the program we would save everything back
|
||||
config->Write("LastPrompt", str);
|
||||
config->Write("/LastRun/CalculatedValues/MaxValue", value);
|
||||
|
||||
// the changes will be written back automatically
|
||||
delete config;
|
||||
\end{verbatim}
|
||||
|
||||
This basic example, of course, doesn't show all wxConfig features, such as
|
||||
enumerating, testing for existence and deleting the entries and groups of
|
||||
entries in the config file, its abilities to automatically store the default
|
||||
values or expand the environment variables on the fly. However, the main idea
|
||||
is that using this class is easy and that it should normally do what you
|
||||
expect it to.
|
||||
|
||||
NB: in the documentation of this class, the words "config file" also mean
|
||||
"registry hive" for wxRegConfig and, generally speaking, might mean any
|
||||
physical storage where a wxConfigBase-derived class stores its data.

||||

||||

\membersection{Static functions}\label{wxconfigstaticfunctions}
|
||||
|
||||
These functions deal with the "default" config object. Although its usage is
|
||||
not at all mandatory it may be convenient to use a global config object
|
||||
instead of creating and deleting the local config objects each time you need
|
||||
one (especially because creating a wxFileConfig object might be a time
|
||||
consuming operation). In this case, you may create this global config object
|
||||
in the very start of the program and {\it Set()} it as the default. Then, from
|
||||
anywhere in your program, you may access it using the {\it Get()} function.
|
||||
Note that wxWindows will delete this config object for you during the program
|
||||
shutdown (from \helpref{wxApp::OnExit}{wxapponexit} to be precise) but you can
|
||||
also do it yourself earlier if needed.
|
||||
|
||||
As it happens, you may even further simplify the procedure described above:
|
||||
you may forget about calling {\it Set()}. When {\it Get()} is called and there
|
||||
is no current object, it will create one using {\it Create()} function. To
|
||||
disable this behaviour {\it DontCreateOnDemand()} is provided.
|
||||
|
||||
{\bf Note:} You should use either {\it Set()} or {\it Get()} because wxWindows
|
||||
library itself would take advantage of it and could save various information
|
||||
in it. For example \helpref{wxFontMapper}{wxfontmapper} or Unix version
|
||||
of \helpref{wxFileDialog}{wxfiledialog} have ability to use wxConfig class.

|
||||
|
||||
\membersection{Path management}
|
||||
|
||||
As explained in \helpref{config overview}{wxconfigoverview}, the config classes
|
||||
support a file system-like hierarchy of keys (files) and groups (directories).
|
||||
As in the file system case, to specify a key in the config class you must use
|
||||
a path to it. Config classes also support the notion of the current group,
|
||||
which makes it possible to use the relative paths. To clarify all this, here
|
||||
is an example (it is only for the sake of demonstration, it doesn't do anything
|
||||
sensible!):
|
||||
|
||||
\begin{verbatim}
|
||||
wxConfig *config = new wxConfig("FooBarApp");
|
||||
|
||||
// right now the current path is '/'
|
||||
conf->Write("RootEntry", 1);
|
||||
|
||||
// go to some other place: if the group(s) don't exist, they will be created
|
||||
conf->SetPath("/Group/Subgroup");
|
||||
|
||||
// create an entry in subgroup
|
||||
conf->Write("SubgroupEntry", 3);
|
||||
|
||||
// '..' is understood
|
||||
conf->Write("../GroupEntry", 2);
|
||||
conf->SetPath("..");
|
||||
|
||||
wxASSERT( conf->Read("Subgroup/SubgroupEntry", 0l) == 3 );
|
||||
|
||||
// use absolute path: it is allowed, too
|
||||
wxASSERT( conf->Read("/RootEntry", 0l) == 1 );
|
||||
\end{verbatim}
|
||||
|
||||
{\it Warning}: it is probably a good idea to always restore the path to its
|
||||
old value on function exit:
|
||||
|
||||
\begin{verbatim}
|
||||
void foo(wxConfigBase *config)
|
||||
{
|
||||
wxString strOldPath = config->GetPath();
|
||||
|
||||
config->SetPath("/Foo/Data");
|
||||
...
|
||||
|
||||
config->SetPath(strOldPath);
|
||||
}
|
||||
\end{verbatim}
|
||||
|
||||
because otherwise the assert in the following example will surely fail
|
||||
(we suppose here that {\it foo()} function is the same as above except that it
|
||||
doesn't save and restore the path):
|
||||
|
||||
\begin{verbatim}
|
||||
void bar(wxConfigBase *config)
|
||||
{
|
||||
config->Write("Test", 17);
|
||||
|
||||
foo(config);
|
||||
|
||||
// we're reading "/Foo/Data/Test" here! -1 will probably be returned...
|
||||
wxASSERT( config->Read("Test", -1) == 17 );
|
||||
}
|
||||
\end{verbatim}
|
||||
|
||||
Finally, the path separator in wxConfigBase and derived classes is always '/',
|
||||
regardless of the platform (i.e. it is {\bf not} '$\backslash\backslash$' under Windows).
|
||||
|
||||
\helpref{SetPath}{wxconfigbasesetpath}\\
|
||||
\helpref{GetPath}{wxconfigbasegetpath}
|
||||
|
||||
\membersection{Enumeration}
|
||||
|
||||
The functions in this section allow to enumerate all entries and groups in the
|
||||
config file. All functions here return FALSE when there are no more items.
|
||||
|
||||
You must pass the same index to GetNext and GetFirst (don't modify it).
|
||||
Please note that it is {\bf not} the index of the current item (you will have
|
||||
some great surprises with wxRegConfig if you assume this) and you shouldn't
|
||||
even look at it: it is just a "cookie" which stores the state of the
|
||||
enumeration. It can't be stored inside the class because it would prevent you
|
||||
from running several enumerations simultaneously, that's why you must pass it
|
||||
explicitly.
|
||||
|
||||
Having said all this, enumerating the config entries/groups is very simple:
|
||||
|
||||
\begin{verbatim}
|
||||
wxArrayString aNames;
|
||||
|
||||
// enumeration variables
|
||||
wxString str;
|
||||
long dummy;
|
||||
|
||||
// first enum all entries
|
||||
bool bCont = config->GetFirstEntry(str, dummy);
|
||||
while ( bCont ) {
|
||||
aNames.Add(str);
|
||||
|
||||
bCont = GetConfig()->GetNextEntry(str, dummy);
|
||||
}
|
||||
|
||||
... we have all entry names in aNames...
|
||||
|
||||
// now all groups...
|
||||
bCont = GetConfig()->GetFirstGroup(str, dummy);
|
||||
while ( bCont ) {
|
||||
aNames.Add(str);
|
||||
|
||||
bCont = GetConfig()->GetNextGroup(str, dummy);
|
||||
}
|
||||
|
||||
... we have all group (and entry) names in aNames...
|
||||
|
||||
\end{verbatim}
|
||||
|
||||
There are also functions to get the number of entries/subgroups without
|
||||
actually enumerating them, but you will probably never need them.

||||

||||

\membersection{Key access}
|
||||
|
||||
These function are the core of wxConfigBase class: they allow you to read and
|
||||
write config file data. All {\it Read} function take a default value which
|
||||
will be returned if the specified key is not found in the config file.
|
||||
|
||||
Currently, only two types of data are supported: string and long (but it might
|
||||
change in the near future). To work with other types: for {\it int} or {\it
|
||||
bool} you can work with function taking/returning {\it long} and just use the
|
||||
casts. Better yet, just use {\it long} for all variables which you're going to
|
||||
save in the config file: chances are that {\tt sizeof(bool) == sizeof(int) == sizeof(long)} anyhow on your system. For {\it float}, {\it double} and, in
|
||||
general, any other type you'd have to translate them to/from string
|
||||
representation and use string functions.
|
||||
|
||||
Try not to read long values into string variables and vice versa: although it
|
||||
just might work with wxFileConfig, you will get a system error with
|
||||
wxRegConfig because in the Windows registry the different types of entries are
|
||||
indeed used.
|
||||
|
||||
Final remark: the {\it szKey} parameter for all these functions can contain an
|
||||
arbitrary path (either relative or absolute), not just the key name.

\membersection{Rename entries/groups}
|
||||
|
||||
The functions in this section allow to rename entries or subgroups of the
|
||||
current group. They will return FALSE on error. typically because either the
|
||||
entry/group with the original name doesn't exist, because the entry/group with
|
||||
the new name already exists or because the function is not supported in this
|
||||
wxConfig implementation.

|
||||
|
||||
\membersection{Delete entries/groups}
|
||||
|
||||
The functions in this section delete entries and/or groups of entries from the
|
||||
config file. {\it DeleteAll()} is especially useful if you want to erase all
|
||||
traces of your program presence: for example, when you uninstall it.

||||
|
||||

|
||||
|
||||
\membersection{Options}
|
||||
|
||||
Some aspects of wxConfigBase behaviour can be changed during run-time. The
|
||||
first of them is the expansion of environment variables in the string values
|
||||
read from the config file: for example, if you have the following in your
|
||||
config file:
|
||||
|
||||
\begin{verbatim}
|
||||
# config file for my program
|
||||
UserData = $HOME/data
|
||||
|
||||
# the following syntax is valud only under Windows
|
||||
UserData = %windir%\\data.dat
|
||||
\end{verbatim}
|
||||
% $ % help EMACS syntax highlighting...
|
||||
the call to {\tt config->Read("UserData")} will return something like
|
||||
{\tt "/home/zeitlin/data"} if you're lucky enough to run a Linux system ;-)
|
||||
|
||||
Although this feature is very useful, it may be annoying if you read a value
|
||||
which containts '\$' or '\%' symbols (\% is used for environment variables
|
||||
expansion under Windows) which are not used for environment variable
|
||||
expansion. In this situation you may call SetExpandEnvVars(FALSE) just before
|
||||
reading this value and SetExpandEnvVars(TRUE) just after. Another solution
|
||||
would be to prefix the offending symbols with a backslash.
|
||||
|
||||
The following functions control this option:
|
||||
|
||||
\helpref{IsExpandingEnvVars}{wxconfigbaseisexpandingenvvars}\\
|
||||
\helpref{SetExpandEnvVars}{wxconfigbasesetexpandenvvars}\\

\docparam{appName}{The application name. If this is empty, the class will

normally use \helpref{wxApp::GetAppName}{wxappgetappname} to set it. The
|
||||
application name is used in the registry key on Windows, and can be used to
|
||||
deduce the local filename parameter if that is missing.}
|
||||
|
||||
\docparam{vendorName}{The vendor name. If this is empty, it is assumed that
|
||||
no vendor name is wanted, if this is optional for the current config class.
|
||||
The vendor name is appended to the application name for wxRegConfig.}
|
||||
|
||||
\docparam{localFilename}{Some config classes require a local filename. If this
|
||||
is not present, but required, the application name will be used instead.}
|
||||
|
||||
\docparam{globalFilename}{Some config classes require a global filename. If
|
||||
this is not present, but required, the application name will be used instead.}
|
||||
|
||||
\docparam{style}{Can be one of wxCONFIG\_USE\_LOCAL\_FILE and
|
||||
wxCONFIG\_USE\_GLOBAL\_FILE. The style interpretation depends on the config
|
||||
class and is ignored by some. For wxFileConfig, these styles determine whether
|
||||
a local or global config file is created or used. If the flag is present but
|
||||
the parameter is empty, the parameter will be set to a default. If the
|
||||
parameter is present but the style flag not, the relevant flag will be added
|
||||
to the style. For wxFileConfig you can also add wxCONFIG\_USE\_RELATIVE\_PATH
|
||||
by logically or'ing it to either of the \_FILE options to tell wxFileConfig to
|
||||
use relative instead of absolute paths. For wxFileConfig, you can also
|
||||
add wxCONFIG\_USE\_NO\_ESCAPE\_CHARACTERS which will turn off character
|
||||
escaping for the values of entries stored in the config file: for example
|
||||
a {\it foo} key with some backslash characters will be stored as {\tt foo=C:$\backslash$mydir} instead
|
||||
of the usual storage of {\tt foo=C:$\backslash\backslash$mydir}.
|
||||
|
||||
The wxCONFIG\_USE\_NO\_ESCAPE\_CHARACTERS style can be helpful if your config
|
||||
file must be read or written to by a non-wxWindows program (which might not
|
||||
understand the escape characters). Note, however, that if
|
||||
wxCONFIG\_USE\_NO\_ESCAPE\_CHARACTERS style is used, it is is now
|
||||
your application's responsibility to ensure that there is no newline or
|
||||
other illegal characters in a value, before writing that value to the file.}

|

Returns the type of the given entry or {\it Unknown} if the entry doesn't
|

exist. This function should be used to decide which version of Read() should
|

be used because some of wxConfig implementations will complain about type
|

mismatch otherwise: e.g., an attempt to read a string value from an integer
|

key with wxRegConfig will fail.
|

|
||||
|

Renames an entry in the current group. The entries names (both the old and
|
||||
the new one) shouldn't contain backslashes, i.e. only simple names and not
|
||||
arbitrary paths are accepted by this function.

Sets the config object as the current one, returns the pointer to the previous
|
||||
current object (both the parameter and returned value may be NULL)
|
||||
|
||||
\membersection{wxConfigBase::SetExpandEnvVars}\label{wxconfigbasesetexpandenvvars}
|

\membersection{wxConfigBase::SetPath}\label{wxconfigbasesetpath}
|
||||
|
||||
\func{void}{SetPath}{\param{const wxString\& }{strPath}}
|
||||
|
||||
Set current path: if the first character is '/', it is the absolute path,
|
||||
otherwise it is a relative path. '..' is supported. If the strPath doesn't
|
||||
exist it is created.
|
||||
|
||||
\membersection{wxConfigBase::SetRecordDefaults}\label{wxconfigbasesetrecorddefaults}
|
||||
|
||||
\func{void}{SetRecordDefaults}{\param{bool }{bDoIt = TRUE}}
|
||||
|
||||
Sets whether defaults are recorded to the config file whenever an attempt to
|
||||
read read the value which is not present in it is done.
|
||||
|
||||
If on (default is off) all default values for the settings used by the program
|
||||
are written back to the config file. This allows the user to see what config
|
||||
options may be changed and is probably useful only for wxFileConfig.

||||
|
||||
\membersection{wxConfigBase::SetUmask}\label{wxfileconfigsetumask}
|

\func{void}{SetUmask}{\param{int }{mode}}
|

{\bf NB:} this function is not in the base wxConfigBase class but is only
|
||||
implemented in wxFileConfig. Moreover, this function is Unix-specific and
|
||||
doesn't do anything on other platforms.
|
||||
|
||||
SetUmask() allows to set the mode to be used for the config file creation.
|
||||
For example, to create a config file which is not readable by other users
|
||||
(useful if it stores some sensitive information, such as passwords), you
|
||||
should do {\tt SetUmask(0077)}.

\section{\class{wxCountingOutputStream}}\label{wxcountingoutputstream}
|
||||
|
||||
wxCountingOutputStream is a specialized output stream which does not write any data anyway,
|
||||
instead it counts how many bytes would get written if this were a normal stream. This
|
||||
can sometimes be useful or required if some data gets serialized to a stream or compressed
|
||||
by using stream compression and thus the final size of the stream cannot be known other
|
||||
than pretending to write the stream. One case where the resulting size would have to be
|
||||
known is if the data has to be written to a piece of memory and the memory has to be
|
||||
allocated before writing to it (which is probably always the case when writing to a
|
||||
memory stream).

\section{\class{wxCriticalSection}}\label{wxcriticalsection}
|

|
||||
A critical section object is used for exactly the same purpose as
|
||||
\helpref{mutexes}{wxmutex}. The only difference is that under Windows platform
|
||||
critical sections are only visible inside one process, while mutexes may be
|
||||
shared between processes, so using critical sections is slightly more
|
||||
efficient. The terminology is also slightly different: mutex may be locked (or
|
||||
acquired) and unlocked (or released) while critical section is entered and left
|
||||
by the program.
|
||||
|
||||
Finally, you should try to use
|
||||
\helpref{wxCriticalSectionLocker}{wxcriticalsectionlocker} class whenever
|
||||
possible instead of directly using wxCriticalSection for the same reasons
|

\helpref{wxMutexLocker}{wxmutexlocker} is preferrable to

\helpref{wxMutex}{wxmutex} - please see wxMutex for an example.

\section{\class{wxCriticalSectionLocker}}\label{wxcriticalsectionlocker}
|
||||
|
||||
This is a small helper class to be used with \helpref{wxCriticalSection}{wxcriticalsection}
|
||||
objects. A wxCriticalSectionLocker enters the critical section in the
|
||||
constructor and leaves it in the destructor making it much more difficult to
|
||||
forget to leave a critical section (which, in general, will lead to serious
|
||||
and difficult to debug problems).
|
||||
|
||||
Example of using it:
|
||||
|
||||
\begin{verbatim}
|
||||
void Set Foo()
|
||||
{
|
||||
// gs_critSect is some (global) critical section guarding access to the
|
||||
// object "foo"
|

wxCriticalSectionLocker locker(gs_critSect);

if ( ... )

// do something

...

\section{\class{wxContextHelp}}\label{wxcontexthelp}
|
||||
|
||||
This class changes the cursor to a query and puts the application into a 'context-sensitive help mode'.
|
||||
When the user left-clicks on a window within the specified window, a wxEVT\_HELP event is
|
||||
sent to that control, and the application may respond to it by popping up some help.
|
||||
|
||||
For example:
|
||||
|
||||
\begin{verbatim}
|
||||
wxContextHelp contextHelp(myWindow);
|
||||
\end{verbatim}
|
||||
|
||||
There are a couple of ways to invoke this behaviour implicitly:
|
||||
|
||||
\begin{itemize}
|
||||
\item Use the wxDIALOG\_EX\_CONTEXTHELP style for a dialog (Windows only). This will put a question mark
|
||||
in the titlebar, and Windows will put the application into context-sensitive help mode automatically,
|
||||
with further programming.
|
||||
\item Create a \helpref{wxContextHelpButton}{wxcontexthelpbutton}, whose predefined behaviour is to create a context help object.
|
||||
Normally you will write your application so that this button is only added to a dialog for non-Windows platforms
|
||||
(use wxDIALOG\_EX\_CONTEXTHELP on Windows).

{\it doNow} is TRUE (the default).
|

\membersection{wxContextHelp::\destruct{wxContextHelp}}

|
||||
|

\func{bool}{BeginContextHelp}{\param{wxWindow*}{ window = NULL}}
|
||||
|
||||
Puts the application into context-sensitive help mode. {\it window} is the window
|
||||
which will be used to catch events; if NULL, the top window will be used.
|
||||
|
||||
Returns TRUE if the application was successfully put into context-sensitive help mode.
|
||||
This function only returns when the event loop has finished.
|
||||
|
||||
\membersection{wxContextHelp::EndContextHelp}\label{wxcontexthelpendcontexthelp}
|
||||
|
||||
\func{bool}{EndContextHelp}{\void}
|
||||
|
||||
Ends context-sensitive help mode. Not normally called by the application.
|
||||
|
||||
\section{\class{wxContextHelpButton}}\label{wxcontexthelpbutton}
|
||||
|
||||
Instances of this class may be used to add a question mark button that when pressed, puts the
|
||||
application into context-help mode. It does this by creating a \helpref{wxContextHelp}{wxcontexthelp} object which itself
|
||||
generates a wxEVT\_HELP event when the user clicks on a window.
|
||||
|
||||
On Windows, you may add a question-mark icon to a dialog by use of the wxDIALOG\_EX\_CONTEXTHELP extra style, but
|
||||
on other platforms you will have to add a button explicitly, usually next to OK, Cancel or similar buttons.

\section{\class{wxControlWithItems}}\label{wxcontrolwithitems}
|
||||
|
||||
This class is an abstract base class for some wxWindows controls which contain
|
||||
several items, such as \helpref{wxListBox}{wxlistbox} and
|
||||
\helpref{wxCheckListBox}{wxchecklistbox} derived from it,
|
||||
\helpref{wxChoice}{wxchoice} and \helpref{wxComboBox}{wxcombobox}.
|
||||
|
||||
It defines the methods for accessing the controls items and although each of
|
||||
the derived classes implements them differently, they still all conform to the
|
||||
same interface.
|
||||
|
||||
The items in a wxControlWithItems have (non empty) string labels and,
|
||||
optionally, client data associated with them. Client data may be of two
|
||||
different kinds: either simple untyped ({\tt void *}) pointers which are simply
|
||||
stored by the control but not used in any way by it, or typed pointers
|
||||
({\tt wxClientData *}) which are owned by the control meaning that the typed
|
||||
client data (and only it) will be deleted when an item is
|
||||
\helpref{deleted}{wxcontrolwithitemsdelete} or the entire control is
|
||||
\helpref{cleared}{wxcontrolwithitemsclear} (which also happens when it is
|
||||
destroyed). Finally note that in the same control all items must have client
|
||||
data of the same type (typed or untyped), if any. This type is determined by
|
||||
the first call to \helpref{Append}{wxcontrolwithitemsappend} (the version with
|
||||
client data pointer) or \helpref{SetClientData}{wxcontrolwithitemssetclientdata}.

|
||||
\func{void}{Append}{\param{const wxArrayString\& }{strings}}
|
||||
|
||||
Appends several items at once to the control. Notice that calling this method
|

may be much faster than appending the items one by one if you need to add a lot
|
||||
of items.

||||
|

\wxheading{Return value}
|
||||
|
||||
When appending a single item, the return value is the index of the newly added
|
||||
item which may be different from the last one if the control is sorted (e.g.
|
||||
has {\tt wxLB\_SORT} or {\tt wxCB\_SORT} style).

\func{void}{Clear}{\void}
|
||||
|
||||
Removes all items from the control.
|
||||
|
||||
{\it Clear()} also deletes the client data of the existing items if it is owned
|
||||
by the control.

||||
|

\membersection{wxControlWithItems::Delete}\label{wxcontrolwithitemsdelete}
|
||||
|

\func{void}{Delete}{\param{int}{ n}}
|
||||
|
||||
Deletes an item from the control. The client data associated with the item
|
||||
will be also deleted if it is owned by the control.
|
||||
|
||||
Note that it is an error (signalled by an assert failure in debug builds) to
|
||||
remove an item with the index negative or greater or equal than the number of
|
||||
items in the control.

\constfunc{void *}{GetClientData}{\param{int}{ n}}
|
||||
|
||||
Returns a pointer to the client data associated with the given item (if any).
|
||||
It is an error to call this function for a control which doesn't have untyped
|
||||
client data at all although it is ok to call it even if the given item doesn't
|
||||
have any client data associated with it (but other items do).

\section{\class{wxCursor}}\label{wxcursor}
|
||||
|
||||
A cursor is a small bitmap usually used for denoting where the mouse
|
||||
pointer is, with a picture that might indicate the interpretation of a
|
||||
mouse click. As with icons, cursors in X and MS Windows are created
|
||||
in a different manner. Therefore, separate cursors will be created for the
|
||||
different environments. Platform-specific methods for creating a {\bf
|
||||
wxCursor} object are catered for, and this is an occasion where
|
||||
conditional compilation will probably be required (see \helpref{wxIcon}{wxicon} for
|
||||
an example).
|
||||
|
||||
A single cursor object may be used in many windows (any subwindow type).
|
||||
The wxWindows convention is to set the cursor for a window, as in X,
|
||||
rather than to set it globally as in MS Windows, although a
|
||||
global \helpref{::wxSetCursor}{wxsetcursor} is also available for MS Windows use.

\param{int }{ height}, \param{int }{hotSpotX=-1}, \param{int }{hotSpotY=-1}, \param{const char }{maskBits[]=NULL}}
|
||||
|
||||
Constructs a cursor by passing an array of bits (Motif and Xt only). {\it maskBits} is used only under Motif.
|
||||
|
||||
If either {\it hotSpotX} or {\it hotSpotY} is -1, the hotspot will be the centre of the cursor image (Motif only).
|
||||
|
||||
\func{}{wxCursor}{\param{const wxString\& }{cursorName}, \param{long }{type}, \param{int }{hotSpotX=0}, \param{int }{hotSpotY=0}}
|
||||
|
||||
Constructs a cursor by passing a string resource name or filename.
|
||||
|
||||
On MacOS when specifying a string resource name, first the color cursors 'crsr' and then the black/white cursors 'CURS' in the resource chain are scanned through.
|
||||
|
||||
{\it hotSpotX} and {\it hotSpotY} are currently only used under Windows when loading from an
|
||||
icon file, to specify the cursor hotspot relative to the top left of the image.
|
||||
|
||||
\func{}{wxCursor}{\param{int}{ cursorId}}
|
||||
|
||||
Constructs a cursor using a cursor identifier.
|
||||
|
||||
\func{}{wxCursor}{\param{const wxImage\&}{ image}}
|
||||
|
||||
Constructs a cursor from a wxImage. The cursor is monochrome, colors with the RGB elements all greater
|
||||
than 127 will be foreground, colors less than this background. The mask (if any) will be used as transparent.
|
||||
|
||||
In MSW the foreground will be white and the background black. The cursor is resized to 32x32
|
||||
In GTK, the two most frequent colors will be used for foreground and background. The cursor will be displayed
|
||||
at the size of the image.
|
||||
On MacOS the cursor is resized to 16x16 and currently only shown as black/white (mask respected).

wxCustomDataObject is a specialization of

\helpref{wxDataObjectSimple}{wxdataobjectsimple} for some

application-specific data in arbitrary (either custom or one of the standard
|
||||
ones). The only restriction is that it is supposed that this data can be

||||
copied bitwise (i.e. with {\tt memcpy()}), so it would be a bad idea to make
|

it contain a C++ object (though C struct is fine).
|

By default, wxCustomDataObject stores the data inside in a buffer. To put the

data into the buffer you may use either

\helpref{SetData}{wxcustomdataobjectsetdata} or

\helpref{TakeData}{wxcustomdataobjecttakedata} depending on whether you want

the object to make a copy of data or not.

If you already store the data in another place, it may be more convenient and

efficient to provide the data on-demand which is possible too if you override

the virtual functions mentioned below.

\helpref{GetData}{wxcustomdataobjectgetdata} and

calls a virtual \helpref{Free()}{wxcustomdataobjectfree} function, the base

class version will always be called (C++ doesn't allow calling virtual

functions from constructors or destructors), so if you override {\tt Free()}, you

should override the destructor in your class as well (which would probably

just call the derived class' version of {\tt Free()}).

\section{\class{wxDataFormat}}\label{wxdataformat}
|
||||
|
||||
A wxDataFormat is an encapsulation of a platform-specific format handle which
|
||||
is used by the system for the clipboard and drag and drop operations. The
|
||||
applications are usually only interested in, for example, pasting data from the
|
||||
clipboard only if the data is in a format the program understands and a data
|
||||
format is something which uniquely identifies this format.
|
||||
|
||||
On the system level, a data format is usually just a number ({\tt CLIPFORMAT}
|
||||
under Windows or {\tt Atom} under X11, for example) and the standard formats
|
||||
are, indeed, just numbers which can be implicitly converted to wxDataFormat.
|
||||
The standard formats are:
|
||||
|
||||
\begin{twocollist}\itemsep=1cm
|
||||
\twocolitem{wxDF\_INVALID}{An invalid format - used as default argument for
|
||||
functions taking a wxDataFormat argument sometimes}
|
||||
\twocolitem{wxDF\_TEXT}{Text format (wxString)}
|
||||
\twocolitem{wxDF\_BITMAP}{A bitmap (wxBitmap)}
|
||||
\twocolitem{wxDF\_METAFILE}{A metafile (wxMetafile, Windows only)}
|
||||
\twocolitem{wxDF\_FILENAME}{A list of filenames}
|
||||
\twocolitem{wxDF\_HTML}{An HTML string. This is only valid when passed to wxSetClipboardData
|
||||
when compiled with Visual C++ in non-Unicode mode}
|
||||
\end{twocollist}
|
||||
|
||||
As mentioned above, these standard formats may be passed to any function taking
|
||||
wxDataFormat argument because wxDataFormat has an implicit conversion from
|
||||
them (or, to be precise from the type {\tt wxDataFormat::NativeFormat} which is
|
||||
the type used by the underlying platform for data formats).
|
||||
|
||||
Aside the standard formats, the application may also use custom formats which
|
||||
are identified by their names (strings) and not numeric identifiers. Although
|
||||
internally custom format must be created (or {\it registered}) first, you
|
||||
shouldn't care about it because it is done automatically the first time the
|
||||
wxDataFormat object corresponding to a given format name is created. The only
|
||||
implication of this is that you should avoid having global wxDataFormat objects
|
||||
with non-default constructor because their constructors are executed before the
|
||||
program has time to perform all necessary initialisations and so an attempt to
|
||||
do clipboard format registration at this time will usually lead to a crash!

\section{\class{wxDataObject}}\label{wxdataobject}
|
||||
|
||||
A wxDataObject represents data that can be copied to or from the clipboard, or
|
||||
dragged and dropped. The important thing about wxDataObject is that this is a
|
||||
'smart' piece of data unlike usual 'dumb' data containers such as memory
|
||||
buffers or files. Being 'smart' here means that the data object itself should
|
||||
know what data formats it supports and how to render itself in each of
|
||||
supported formats.
|
||||
|
||||
A supported format, incidentally, is exactly the format in which the data can
|
||||
be requested from a data object or from which the data object may be set. In
|
||||
the general case, an object may support different formats on 'input' and
|
||||
'output', i.e. it may be able to render itself in a given format but not be
|
||||
created from data on this format or vice versa. wxDataObject defines an
|
||||
enumeration type
|
||||
|
||||
\begin{verbatim}
|
||||
enum Direction
|
||||
{
|
||||
Get = 0x01, // format is supported by GetDataHere()
|
||||
Set = 0x02 // format is supported by SetData()
|
||||
};
|
||||
\end{verbatim}
|
||||
|
||||
which allows to distinguish between them. See
|
||||
\helpref{wxDataFormat}{wxdataformat} documentation for more about formats.
|
||||
|
||||
Not surprisingly, being 'smart' comes at a price of added complexity. This is
|
||||
reasonable for the situations when you really need to support multiple formats,
|
||||
but may be annoying if you only want to do something simple like cut and paste
|
||||
text.
|
||||
|
||||
To provide a solution for both cases, wxWindows has two predefined classes
|
||||
which derive from wxDataObject: \helpref{wxDataObjectSimple}{wxdataobjectsimple} and
|
||||
\helpref{wxDataObjectComposite}{wxdataobjectcomposite}.
|
||||
\helpref{wxDataObjectSimple}{wxdataobjectsimple} is
|
||||
the simplest wxDataObject possible and only holds data in a single format (such
|
||||
as HTML or text) and \helpref{wxDataObjectComposite}{wxdataobjectcomposite} is
|
||||
the simplest way to implement wxDataObject which does support multiple formats
|
||||
because it achievs this by simply holding several wxDataObjectSimple objects.
|
||||
|
||||
So, you have several solutions when you need a wxDataObject class (and you need
|
||||
one as soon as you want to transfer data via the clipboard or drag and drop):
|
||||
|
||||
\begin{twocollist}\itemsep=1cm
|
||||
\twocolitem{{\bf 1. Use one of the built-in classes}}{You may use wxTextDataObject,
|
||||
wxBitmapDataObject or wxFileDataObject in the simplest cases when you only need
|
||||
to support one format and your data is either text, bitmap or list of files.}
|
||||
\twocolitem{{\bf 2. Use wxDataObjectSimple}}{Deriving from wxDataObjectSimple is the simplest
|
||||
solution for custom data - you will only support one format and so probably
|
||||
won't be able to communicate with other programs, but data transfer will work
|
||||
in your program (or between different copies of it).}
|
||||
\twocolitem{{\bf 3. Use wxDataObjectComposite}}{This is a simple but powerful
|
||||
solution which allows you to support any number of formats (either
|
||||
standard or custom if you combine it with the previous solution).}

\twocolitem{{\bf 4. Use wxDataObject directly}}{This is the solution for
|

maximal flexibility and efficiency, but it is also is the most difficult to
|
||||
implement.}
|
||||
\end{twocollist}
|
||||
|
||||
Please note that the easiest way to use drag and drop and the clipboard with
|
||||
multiple formats is by using wxDataObjectComposite, but it is not the most
|
||||
efficient one as each wxDataObjectSimple would contain the whole data in its
|
||||
respective formats. Now imagine that you want to paste 200 pages of text in
|
||||
your proprietary format, as well as Word, RTF, HTML, Unicode and plain text to
|
||||
the clipboard and even today's computers are in trouble. For this case, you
|
||||
will have to derive from wxDataObject directly and make it enumerate its
|
||||
formats and provide the data in the requested format on demand.
|
||||
|
||||
Note that neither the GTK data transfer mechanisms for the clipboard and
|
||||
drag and drop, nor the OLE data transfer copy any data until another application
|
||||
actually requests the data. This is in contrast to the 'feel' offered to the
|
||||
user of a program who would normally think that the data resides in the
|
||||
clipboard after having pressed 'Copy' - in reality it is only declared to be
|
||||
available.
|
||||
|
||||
There are several predefined data object classes derived from
|
||||
wxDataObjectSimple: \helpref{wxFileDataObject}{wxfiledataobject},
|
||||
\helpref{wxTextDataObject}{wxtextdataobject} and
|
||||
\helpref{wxBitmapDataObject}{wxbitmapdataobject} which can be used without
|
||||
change.
|
||||
|
||||
You may also derive your own data object classes from
|
||||
\helpref{wxCustomDataObject}{wxcustomdataobject} for user-defined types. The
|
||||
format of user-defined data is given as mime-type string literal, such as
|
||||
"application/word" or "image/png". These strings are used as they are under
|
||||
Unix (so far only GTK) to identify a format and are translated into their
|
||||
Windows equivalent under Win32 (using the OLE IDataObject for data exchange to
|
||||
and from the clipboard and for drag and drop). Note that the format string
|
||||
translation under Windows is not yet finished.
|
||||
|
||||
\pythonnote{At this time this class is not directly usable from wxPython.
|
||||
Derive a class from \helpref{wxPyDataObjectSimple}{wxdataobjectsimple}
|
||||
instead.}
|
||||
|
||||
\perlnote{This class is not currently usable from wxPerl; you may

use \helpref{Wx::PlDataObjectSimple}{wxdataobjectsimple} instead.}
|
||||
|
||||
\wxheading{Virtual functions to override}
|
||||
|
||||
Each class derived directly from wxDataObject must override and implement all
|
||||
of its functions which are pure virtual in the base class.
|
||||
|
||||
The data objects which only render their data or only set it (i.e. work in
|
||||
only one direction), should return 0 from

\helpref{GetFormatCount}{wxdataobjectgetformatcount}.

\section{\class{wxDateSpan}}\label{wxdatespan}
|
||||
|
||||
This class is a "logical time span" and is useful for implementing program
|
||||
logic for such things as "add one month to the date" which, in general,
|
||||
doesn't mean to add $60*60*24*31$ seconds to it, but to take the same date
|
||||
the next month (to understand that this is indeed different consider adding
|
||||
one month to Feb, 15 -- we want to get Mar, 15, of course).
|
||||
|
||||
When adding a month to the date, all lesser components (days, hours, ...)
|
||||
won't be changed unless the resulting date would be invalid: for example,
|
||||
Jan 31 + 1 month will be Feb 28, not (non existing) Feb 31.
|
||||
|
||||
Because of this feature, adding and subtracting back again the same
|
||||
wxDateSpan will {\bf not}, in general give back the original date: Feb 28 - 1
|
||||
month will be Jan 28, not Jan 31!
|
||||
|
||||
wxDateSpan objects can be either positive or negative. They may be
|
||||
multiplied by scalars which multiply all deltas by the scalar: i.e.
|
||||
$2*(1 \hbox{ month and } 1 \hbox{ day})$ is $2$ months and $2$ days. They can
|
||||
be added together and with \helpref{wxDateTime}{wxdatetime} or
|
||||
\helpref{wxTimeSpan}{wxtimespan}, but the type of result is different for each
|
||||
case.
|
||||
|
||||
Beware about weeks: if you specify both weeks and days, the total number of
|
||||
days added will be $7*\hbox{weeks} + \hbox{days}$! See also GetTotalDays()
|
||||
function.
|
||||
|
||||
Equality operators are defined for wxDateSpans. Two datespans are equal if
|
||||
and only if they both give the same target date when added to {\bf every}
|
||||
source date. Thus wxDateSpan::Months(1) is not equal to wxDateSpan::Days(30),
|
||||
because they not give the same date when added to 1 Feb. But
|
||||
wxDateSpan::Days(14) is equal to wxDateSpan::Weeks(2)
|
||||
|
||||
Finally, notice that for adding hours, minutes and so on you don't need this
|
||||
class at all: \helpref{wxTimeSpan}{wxtimespan} will do the job because there
|
||||
are no subtleties associated with those (we don't support leap seconds).

\section{\class{wxDataInputStream}}\label{wxdatainputstream}
|
||||
|
||||
This class provides functions that read binary data types in a
|
||||
portable way. Data can be read in either big-endian or little-endian
|
||||
format, little-endian being the default on all architectures.
|
||||
|
||||
If you want to read data from text files (or streams) use
|
||||
\helpref{wxTextInputStream}{wxtextinputstream} instead.
|
||||
|
||||
The >> operator is overloaded and you can use this class like a standard C++ iostream.
|
||||
Note, however, that the arguments are the fixed size types wxUint32, wxInt32 etc
|
||||
and on a typical 32-bit computer, none of these match to the "long" type (wxInt32
|
||||
is defined as signed int on 32-bit architectures) so that you cannot use long. To avoid
|
||||
problems (here and elsewhere), make use of the wxInt32, wxUint32, etc types.
|
||||
|
||||
For example:
|
||||
|
||||
\begin{verbatim}
|
||||
wxFileInputStream input( "mytext.dat" );
|
||||
wxDataInputStream store( input );
|
||||
wxUint8 i1;
|
||||
float f2;
|
||||
wxString line;
|
||||
|
||||
store >> i1; // read a 8 bit integer.
|
||||
store >> i1 >> f2; // read a 8 bit integer followed by float.
|
||||
store >> line; // read a text line

||||

In ANSI build of wxWindows, the string is written to the stream in exactly
|

same way it is represented in memory. In Unicode build, however, the string
|
||||
is first converted to multibyte representation with {\it conv} object passed
|

to stream's constructor (consequently, ANSI application can read data
|
||||
written by Unicode application, as long as they agree on encoding) and this
|
||||
representation is written to the stream. UTF-8 is used by default.

\section{\class{wxDDEClient}}\label{wxddeclient}
|
||||
|
||||
A wxDDEClient object represents the client part of a client-server DDE
|
||||
(Dynamic Data Exchange) conversation.
|
||||
|
||||
To create a client which can communicate with a suitable server,
|
||||
you need to derive a class from wxDDEConnection and another from wxDDEClient.
|
||||
The custom wxDDEConnection class will intercept communications in
|
||||
a `conversation' with a server, and the custom wxDDEServer is required
|
||||
so that a user-overridden \helpref{wxDDEClient::OnMakeConnection}{wxddeclientonmakeconnection} member can return
|
||||
a wxDDEConnection of the required class, when a connection is made.
|
||||
|
||||
This DDE-based implementation is
|
||||
available on Windows only, but a platform-independent, socket-based version
|
||||
of this API is available using \helpref{wxTCPClient}{wxtcpclient}.

own derived connection object. By default, a wxDDEConnection

\section{\class{wxDDEConnection}}\label{wxddeconnection}
|
||||
|
||||
A wxDDEConnection object represents the connection between a client and a
|
||||
server. It can be created by making a connection using a\rtfsp
|
||||
\helpref{wxDDEClient}{wxddeclient} object, or by the acceptance of a connection by a\rtfsp
|
||||
\helpref{wxDDEServer}{wxddeserver} object. The bulk of a DDE (Dynamic Data Exchange)
|
||||
conversation is controlled by
|
||||
calling members in a {\bf wxDDEConnection} object or by overriding its
|
||||
members.
|
||||
|
||||
An application should normally derive a new connection class from
|

wxDDEConnection, in order to override the communication event handlers
|
||||
to do something interesting.

|
||||
|

\func{void}{SetDebugMode}{\param{bool}{ debug}}
|
||||
|
||||
Sets the debug mode on or off. If debug mode is on, the wxObject new and delete
|
||||
operators store or use information about memory allocation. Otherwise,
|
||||
a straight malloc and free will be performed by these operators.
|
||||
|
||||
By default, debug mode is on if \_\_WXDEBUG\_\_ is defined. If the application
|
||||
uses this function, it should make sure that all object memory allocated
|
||||
is deallocated with the same value of debug mode. Otherwise, the
|

delete operator might try to look for memory information that does not
|

exist.

|
||||
|

Sets the current debug file and creates a stream. This will delete any existing
|
||||
stream and stream buffer. By default, the debug context stream
|
||||
outputs to the debugger (Windows) or standard error (other platforms).
|

\membersection{wxDebugContext::SetLevel}\label{wxdebugcontextsetlevel}
|

\func{void}{SetLevel}{\param{int}{ level}}
|

Sets the debug level (default 1). The debug level is used by the wxTraceLevel function and
|
||||
the WXTRACELEVEL macro to specify how detailed the trace information is; setting
|
||||
a different level will only have an effect if trace statements in the application
|
||||
specify a value other than one.

This class allows you to treat debugging output in a similar

(stream-based) fashion on different platforms. Under

Windows, an ostream constructed with this buffer outputs

to the debugger, or other program that intercepts debugging

output. On other platforms, the output goes to standard error (cerr).

\section{\class{wxDialog}}\label{wxdialog}
|
||||
|
||||
A dialog box is a window with a title bar and sometimes a system menu, which
|
||||
can be moved around the screen. It can contain controls and other windows and
|
||||
is usually used to allow the user to make some choice or to answer a question.

||||

||||

<wx/dialog.h>
|
||||
|
||||
\wxheading{Remarks}
|
||||
|
||||
There are two kinds of dialog -- {\it modal}\ and {\it modeless}. A modal dialog
|
||||
blocks program flow and user input on other windows until it is dismissed,
|
||||
whereas a modeless dialog behaves more like a frame in that program flow
|
||||
continues, and input on other windows is still possible. To show a modal dialog
|
||||
you should use \helpref{ShowModal}{wxdialogshowmodal} method while to show
|
||||
dialog modelessly you simply use \helpref{Show}{wxdialogshow}, just as with the
|
||||
frames.
|
||||
|
||||
Note that the modal dialogs are one of the very few examples of
|
||||
wxWindow-derived objects which may be created on the stack and not on the heap.
|
||||
In other words, although this code snippet
|
||||
\begin{verbatim}
|
||||
void AskUser()
|
||||
{
|
||||
MyAskDialog *dlg = new MyAskDialog(...);
|
||||
if ( dlg->ShowModal() == wxID_OK )
|
||||
...
|
||||
//else: dialog was cancelled or some another button pressed
|
||||
|
||||
dlg->Destroy();
|
||||
}
|
||||
\end{verbatim}
|
||||
works, you can also achieve the same result by using a simpler code fragment
|
||||
below:
|
||||
\begin{verbatim}
|
||||
void AskUser()
|
||||
{
|
||||
MyAskDialog dlg(...);
|
||||
if ( dlg.ShowModal() == wxID_OK )
|
||||
...
|
||||
|
||||
// no need to call Destroy() here
|
||||
}
|
||||
\end{verbatim}
|
||||
|
||||
A dialog may be loaded from a wxWindows resource file (extension {\tt wxr}),
|
||||
which may itself be created by Dialog Editor. For details, see
|
||||
\helpref{The wxWindows resource system}{resourceformats},
|
||||
\helpref{wxWindows resource functions}{resourcefuncs}
|
||||
and the resource sample.
|
||||
|
||||
An application can define an \helpref{wxCloseEvent}{wxcloseevent} handler for
|
||||
the dialog to respond to system close events.

boxes under Motif which have user-iconizable frames, and under Windows

{\bf NB:} This function is deprecated and doesn't work for all ports, just use
|
||||
\helpref{ShowModal}{wxdialogshowmodal} to show a modal dialog instead.
|
||||
|
||||
Allows the programmer to specify whether the dialog box is modal (wxDialog::Show blocks control
|
||||
until the dialog is hidden) or modeless (control returns immediately).
|

|
||||
\docparam{retCode}{The integer return code, usually a control identifier.}
|
||||
|

\wxheading{Remarks}
|
||||
|

\docparam{show}{If TRUE, the dialog box is shown and brought to the front;
|
||||
otherwise the box is hidden. If FALSE and the dialog is
|
||||
modal, control is returned to the calling program.}
|
||||
|
||||
\wxheading{Remarks}
|
||||
|
||||
The preferred way of dismissing a modal dialog is to use \helpref{wxDialog::EndModal}{wxdialogendmodal}.
|
||||
|
||||
\membersection{wxDialog::ShowModal}\label{wxdialogshowmodal}
|
||||
|
||||
\func{int}{ShowModal}{\void}
|
||||
|

\section{\class{wxDialUpManager}}\label{wxdialupmanager}
|
||||
|
||||
This class encapsulates functions dealing with verifying the connection status
|
||||
of the workstation (connected to the Internet via a direct connection,
|
||||
connected through a modem or not connected at all) and to establish this
|
||||
connection if possible/required (i.e. in the case of the modem).
|
||||
|
||||
The program may also wish to be notified about the change in the connection
|
||||
status (for example, to perform some action when the user connects to the
|
||||
network the next time or, on the contrary, to stop receiving data from the net
|
||||
when the user hangs up the modem). For this, you need to use one of the event
|
||||
macros described below.
|
||||
|
||||
This class is different from other wxWindows classes in that there is at most
|
||||
one instance of this class in the program accessed via
|
||||
\helpref{wxDialUpManager::Create()}{wxdialupmanagercreate} and you can't
|
||||
create the objects of this class directly.

\membersection{wxDialUpManager::Create}\label{wxdialupmanagercreate}

\func{wxDialUpManager*}{Create}{\void}
|
||||
|
||||
This function should create and return the object of the platform-specific
|
||||
class derived from wxDialUpManager. You should delete the pointer when you are
|
||||
done with it.
|
||||
|
||||
\membersection{wxDialUpManager::IsOk}\label{wxdialupmanagerisok}
|
||||
|
||||
\constfunc{bool}{IsOk}{\void}
|
||||
|
||||
Returns {\tt TRUE} if the dialup manager was initialized correctly. If this
|
||||
function returns {\tt FALSE}, no other functions will work neither, so it is a
|
||||
good idea to call this function and check its result before calling any other
|
||||
wxDialUpManager methods
|
||||
|
||||
\membersection{wxDialUpManager::\destruct{wxDialUpManager}}\label{wxdialupmanagerdtor}

\func{}{\destruct{wxDialUpManager}}{\void}
|

|

Destructor.
|

|
||||
\membersection{wxDialUpManager::GetISPNames}\label{wxdialupmanagergetispnames}
|
||||
|
||||
\constfunc{size\_t}{GetISPNames}{\param{wxArrayString\& }{names}}
|
||||
|
||||
This function is only implemented under Windows.
|
||||
|
||||
Fills the array with the names of all possible values for the first
|
||||
parameter to \helpref{Dial()}{wxdialupmanagerdial} on this machine and returns
|
||||
their number (may be $0$).
|
||||
|
||||
\membersection{wxDialUpManager::Dial}\label{wxdialupmanagerdial}
|
||||
|
||||
\func{bool}{Dial}{\param{const wxString\& }{nameOfISP = wxEmptyString}, \param{const wxString\& }{username = wxEmptyString}, \param{const wxString\& }{password = wxEmptyString}, \param{bool }{async = TRUE}}
|
||||
|
||||
Dial the given ISP, use {\it username} and {\it password} to authenticate.
|
||||
|
||||
The parameters are only used under Windows currently, for Unix you should use
|
||||
\helpref{SetConnectCommand}{wxdialupmanagersetconnectcommand} to customize this
|
||||
functions behaviour.
|
||||
|
||||
If no {\it nameOfISP} is given, the function will select the default one
|
||||
(proposing the user to choose among all connections defined on this machine)
|
||||
and if no username and/or password are given, the function will try to do
|
||||
without them, but will ask the user if really needed.
|
||||
|
||||
If {\it async} parameter is {\tt FALSE}, the function waits until the end of dialing
|
||||
and returns {\tt TRUE} upon successful completion.
|
||||
|
||||
If {\it async} is {\tt TRUE}, the function only initiates the connection and
|
||||
returns immediately - the result is reported via events (an event is sent
|
||||
anyhow, but if dialing failed it will be a DISCONNECTED one).
|
||||
|
||||
\membersection{wxDialUpManager::IsDialing}\label{wxdialupmanagerisdialing}
|
||||
|

\constfunc{bool}{IsDialing}{\void}

Returns TRUE if (async) dialing is in progress.

|
||||
|
||||
\func{bool}{CancelDialing}{\void}
|
||||
|
||||
Cancel dialing the number initiated with \helpref{Dial}{wxdialupmanagerdial}
|
||||
with async parameter equal to {\tt TRUE}.
|
||||
|
||||
Note that this won't result in DISCONNECTED event being sent.

\membersection{wxDialUpManager::HangUp}\label{wxdialupmanagerhangup}
|
||||
|
||||
\func{bool}{HangUp}{\void}
|
||||
|
||||
Hang up the currently active dial up connection.
|
||||
|
||||
\membersection{wxDialUpManager::IsAlwaysOnline}\label{wxdialupmanagerisalwaysonline}
|
||||
|
||||
\constfunc{bool}{IsAlwaysOnline}{\void}
|
||||
|
||||
Returns {\tt TRUE} if the computer has a permanent network connection (i.e. is
|
||||
on a LAN) and so there is no need to use Dial() function to go online.
|
||||
|
||||
{\bf NB:} this functions tries to guess the result and it is not always
|
||||
guaranteed to be correct, so it is better to ask user for
|
||||
confirmation or give him a possibility to override it.
|
||||
|
||||
\membersection{wxDialUpManager::IsOnline}\label{wxdialupmanagerisonline}
|
||||
|
||||
\constfunc{bool}{IsOnline}{\void}
|
||||
|
||||
Returns {\tt TRUE} if the computer is connected to the network: under Windows,
|
||||
this just means that a RAS connection exists, under Unix we check that
|
||||
the "well-known host" (as specified by
|
||||
\helpref{SetWellKnownHost}{wxdialupmanagersetwellknownhost}) is reachable.
|
||||
|
||||
\membersection{wxDialUpManager::SetOnlineStatus}\label{wxdialupmanagersetonlinestatus}
|
||||
|
||||
\func{void}{SetOnlineStatus}{\param{bool }{isOnline = TRUE}}
|
||||
|
||||
Sometimes the built-in logic for determining the online status may fail,
|
||||
so, in general, the user should be allowed to override it. This function
|
||||
allows to forcefully set the online status - whatever our internal
|
||||
algorithm may think about it.

|
||||
|
||||
\func{bool}{EnableAutoCheckOnlineStatus}{\param{size\_t }{nSeconds = 60}}
|
||||
|
||||
Enable automatic checks for the connection status and sending of
|
||||
{\tt wxEVT\_DIALUP\_CONNECTED/wxEVT\_DIALUP\_DISCONNECTED} events. The interval
|
||||
parameter is only for Unix where we do the check manually and specifies how
|
||||
often should we repeat the check (each minute by default). Under Windows, the
|
||||
notification about the change of connection status is sent by the system and so
|
||||
we don't do any polling and this parameter is ignored.
|
||||
|
||||
Returns {\tt FALSE} if couldn't set up automatic check for online status.
|
||||
|
||||
\membersection{wxDialUpManager::DisableAutoCheckOnlineStatus}\label{wxdialupmanagerdisableautocheckonlinestatus}
|
||||
|
||||
\func{void}{DisableAutoCheckOnlineStatus}{\void}
|
||||
|
||||
Disable automatic check for connection status change - notice that the
|
||||
{\tt wxEVT\_DIALUP\_XXX} events won't be sent any more neither.
|
||||
|
||||
\membersection{wxDialUpManager::SetWellKnownHost}\label{wxdialupmanagersetwellknownhost}
|
||||
|
||||
\func{void}{SetWellKnownHost}{\param{const wxString\& }{hostname}, \param{int }{portno = 80}}
|
||||
|
||||
This method is for Unix only.
|
||||
|
||||
Under Unix, the value of well-known host is used to check whether we're
|
||||
connected to the internet. It is unused under Windows, but this function
|
||||
is always safe to call. The default value is {\tt www.yahoo.com:80}.
|
||||
|
||||
\membersection{wxDialUpManager::SetConnectCommand}\label{wxdialupmanagersetconnectcommand}
|
||||

\func{}{SetConnectCommand}{\param{const wxString\& }{commandDial = wxT("/usr/bin/pon")}, \param{const wxString\& }{commandHangup = wxT("/usr/bin/poff")}}
|
||||
|
||||
This method is for Unix only.
|
||||
|
||||
Sets the commands to start up the network and to hang up again.

\section{\class{wxDir}}\label{wxdir}
|
||||
|
||||
wxDir is a portable equivalent of Unix {open/read/close}dir functions which
|
||||
allow enumerating of the files in a directory. wxDir allows enumerate files as
|
||||
well as directories.
|
||||
|
||||
wxDir also provides a flexible way to enumerate files recursively using
|
||||
\helpref{Traverse}{wxdirtraverse} or a simpler
|
||||
\helpref{GetAllFiles}{wxdirgetallfiles} function.
|
||||
|
||||
Example of use:
|
||||
|
||||
\begin{verbatim}
|
||||
wxDir dir(wxGetCwd());
|
||||
|
||||
if ( !dir.IsOpened() )
|
||||
{
|
||||
// deal with the error here - wxDir would already log an error message
|
||||
// explaining the exact reason of the failure
|
||||
return;
|
||||
}
|
||||
|
||||
puts("Enumerating object files in current directory:");
|
||||
|
||||
wxString filename;
|
||||
|
||||
bool cont = dir.GetFirst(&filename, filespec, flags);
|
||||
while ( cont )
|
||||
{
|
||||
printf("%s\n", filename.c_str());
|

cont = dir.GetNext(&filename);

\constfunc{bool}{GetFirst}{\param{wxString* }{filename}, \param{const wxString\& }{filespec = wxEmptyString}, \param{int }{flags = wxDIR\_DEFAULT}}
|

Start enumerating all files matching {\it filespec} (or all files if it is
|
||||
empty) and flags, return TRUE on success.
|

\membersection{wxDir::GetNext}\label{wxdirgetnext}
|

\membersection{wxDir::HasFiles}\label{wxdirhasfiles}
|
||||
|
||||
\func{bool}{HasFiles}{\param{const wxString\& }{filespec = wxEmptyString}}
|
||||
|
||||
Returns {\tt TRUE} if the directory contains any files matching the given
|
||||
{\it filespec}. If {\it filespec} is empty, look for any files at all. In any
|
||||
case, even hidden files are taken into account.

\membersection{wxDir::HasSubDirs}\label{wxdirhassubdirs}
|
||||
|
||||
\func{bool}{HasSubDirs}{\param{const wxString\& }{dirspec = wxEmptyString}}
|
||||
|
||||
Returns {\tt TRUE} if the directory contains any subdirectories (if a non
|
||||
empty {\it filespec} is given, only check for directories matching it).
|
||||
The hidden subdirectories are taken into account as well.
|

||||
\membersection{wxDir::Traverse}\label{wxdirtraverse}
|
||||
|
||||
\func{size\_t}{Traverse}{\param{wxDirTraverser\& }{sink}, \param{const wxString\& }{filespec = wxEmptyString}, \param{int }{flags = wxDIR\_DEFAULT}}
|
||||
|
||||
Enumerate all files and directories under the given directory recursively
|
||||
calling the element of the provided \helpref{wxDirTraverser}{wxdirtraverser}
|
||||
object for each of them.
|
||||
|
||||
More precisely, the function will really recurse into subdirectories if
|
||||
{\it flags} contains {\tt wxDIR\_DIRS} flag. It will ignore the files (but
|
||||
still possibly recurse into subdirectories) if {\tt wxDIR\_FILES} flag is
|
||||
given.
|
||||
|
||||
For each found directory, \helpref{sink.OnDir()}{wxdirtraverserondir} is called
|
||||
and \helpref{sink.OnFile()}{wxdirtraverseronfile} is called for every file.
|
||||
Depending on the return value, the enumeration may continue or stop.
|
||||
|
||||
The function returns the total number of files found or {\tt (size\_t)-1} on
|
||||
error.

|
||||
|
||||
The function appends the names of all the files under directory {\it dirname}
|
||||
to the array {\it files} (note that its old contents is preserved). Only files
|
||||
matching the {\it filespec} are taken, with empty spec matching all the files.
|
||||
|
||||
The {\it flags} parameter should always include {\tt wxDIR\_FILES} or the array
|
||||
would be unchanged and should include {\tt wxDIR\_DIRS} flag to recurse into
|
||||
subdirectories (both flags are included in the value by default).

\section{\class{wxDllLoader}}\label{wxdllloader}
|
||||
|
||||
wxDllLoader is a class providing an interface similar to Unix's {\tt
|
||||
dlopen()}. It is used by the wxLibrary framework and manages the actual
|
||||
loading of shared libraries and the resolving of symbols in them. There are no
|
||||
instances of this class, it simply serves as a namespace for its static member
|
||||
functions.
|
||||
|
||||
Please note that class \helpref{wxDynamicLibrary}{wxdynamiclibrary} provides
|
||||
alternative, friendlier interface to wxDllLoader.
|
||||
|
||||
The terms {\it DLL} and {\it shared library/object} will both be used in the
|
||||
documentation to refer to the same thing: a {\tt .dll} file under Windows or
|
||||
{\tt .so} or {\tt .sl} one under Unix.
|
||||
|
||||
Example of using this class to dynamically load the {\tt strlen()} function:
|
||||
|
||||
\begin{verbatim}
|
||||
#if defined(__WXMSW__)
|
||||
static const wxChar *LIB_NAME = _T("kernel32");
|
||||
static const wxChar *FUNC_NAME = _T("lstrlenA");
|
||||
#elif defined(__UNIX__)
|
||||
static const wxChar *LIB_NAME = _T("/lib/libc-2.0.7.so");
|
||||
static const wxChar *FUNC_NAME = _T("strlen");

This function loads a shared library into memory, with {\it libname} being the
|
||||
name of the library: it may be either the full name including path and
|
||||
(platform-dependent) extension, just the basename (no path and no extension)

searched in all standard locations.

Returns a handle to the loaded DLL. Use {\it success} parameter to test if it

wxDataObjectComposite is the simplest

\helpref{wxDataObject}{wxdataobject} derivation which may be sued to support
|

multiple formats. It contains several
|

\helpref{wxDataObjectSimple}{wxdataobjectsimple} objects and supports any

format supported by at least one of them. Only one of these data objects is
|

{\it preferred} (the first one if not explicitly changed by using the second
|
||||
parameter of \helpref{Add}{wxdataobjectcompositeadd}) and its format determines
|
||||
the preferred format of the composite data object as well.
|
||||
|
||||
See \helpref{wxDataObject}{wxdataobject} documentation for the reasons why you
|

might prefer to use wxDataObject directly instead of wxDataObjectComposite for

efficiency reasons.

\section{\class{wxDataObjectSimple}}\label{wxdataobjectsimple}

|

This is the simplest possible implementation of the
|
||||
\helpref{wxDataObject}{wxdataobject} class. The data object of (a class derived
|
||||
from) this class only supports one format, so the number of virtual functions
|
||||
to be implemented is reduced.
|
||||
|
||||
Notice that this is still an abstract base class and cannot be used but should
|
||||
be derived from.

|

\pythonnote{If you wish to create a derived wxDataObjectSimple class in
|
||||
wxPython you should derive the class from wxPyDataObjectSimple
|

in order to get Python-aware capabilities for the various virtual

methods.}

\membersection{wxDocManager::Initialize}\label{wxdocmanagerinitialize}
|

\func{bool}{Initialize}{\void}
|
||||
|
||||
Initializes data; currently just calls OnCreateFileHistory. Some data cannot
|
||||
always be initialized in the constructor because the programmer must be given
|
||||
the opportunity to override functionality. If OnCreateFileHistory was called
|
||||
from the constructor, an overridden virtual OnCreateFileHistory would not be
|
||||
called due to C++'s `interesting' constructor semantics. In fact Initialize
|
||||
\rtfsp{\it is} called from the wxDocManager constructor, but this can be
|
||||
vetoed by passing FALSE to the second argument, allowing the derived class's
|
||||
constructor to call Initialize, possibly calling a different OnCreateFileHistory
|
||||
from the default.
|
||||
|
||||
The bottom line: if you're not deriving from Initialize, forget it and
|
||||
construct wxDocManager with no arguments.

\membersection{wxDocManager::MakeDefaultName}
|

\func{bool}{MakeDefaultName}{\param{const wxString\& }{buf}}

the counter.

\func{void}{OnMenuCommand}{\param{int}{ cmd}}
|

Processes menu commands routed from child or parent frames. This deals
|

with the following predefined menu item identifiers:
|
||||
|
||||
\begin{itemize}\itemsep=0pt
|
||||
\item wxID\_OPEN Creates a new document and opens a file into it.

\item wxID\_SAVE Saves the document.
|
||||
\item wxID\_SAVE\_AS Saves the document into a specified filename.

Under Windows, pops up a file selector with a list of filters corresponding to document templates.
|

The wxDocTemplate corresponding to the selected file's extension is returned.
|
||||
|
||||
On other platforms, if there is more than one document template a choice list is popped up,

Returns a document template by asking the user (if there is more than one template),
|

displaying a list of valid views. This function is used in wxDocManager::CreateView.
|

Sets the maximum number of documents that can be open at a time. By default, this

is 10,000. If you set it to 1, existing documents will be saved and deleted
|
||||
when the user tries to open or create a new one (similar to the behaviour
|

of Windows Write, for example). Allowing multiple documents gives behaviour

more akin to MS Word and other Multiple Document Interface applications.

\constfunc{virtual bool}{IsModified}{\void}
|

Returns TRUE if the document has been modified since the last save, FALSE otherwise.
|

You may need to override this if your document view maintains its own
|
||||
record of being modified (for example if using wxTextWindow to view and edit the document).

\func{virtual wxInputStream\&}{LoadObject}{\param{wxInputStream\& }{stream}}
|
||||
|
||||
Override this function and call it from your own LoadObject before
|
||||
streaming your own data. LoadObject is called by the framework
|
||||
automatically when the document contents need to be loaded.
|
||||
|
||||
Note that only one of these forms exists, depending on how wxWindows
|
||||
was configured.

||||
\membersection{wxDocument::Modify}\label{wxdocumentmodify}
|
||||
|
||||
\func{virtual void}{Modify}{\param{bool}{ modify}}
|
||||
|
||||
Call with TRUE to mark the document as modified since the last save, FALSE otherwise.
|
||||
You may need to override this if your document view maintains its own
|
||||
record of being modified (for example if using wxTextWindow to view and edit the document).
|
||||
|
||||
See also \helpref{IsModified}{wxdocumentismodified}.

|
||||
\membersection{wxDocument::OnChangedViewList}
|
||||
|
||||
\func{virtual void}{OnChangedViewList}{\void}
|
||||
|
||||
Called when a view is added to or deleted from this document. The default
|
||||
implementation saves and deletes the document if no views exist (the last
|
||||
one has just been removed).
|
||||
|
||||
\membersection{wxDocument::OnCloseDocument}
|
||||
|
||||
\func{virtual bool}{OnCloseDocument}{\void}
|
||||
|
||||
The default implementation calls DeleteContents (an empty implementation)
|
||||
sets the modified flag to FALSE. Override this to
|
||||
supply additional behaviour when the document is closed with Close.
|
||||
|
||||
\membersection{wxDocument::OnCreate}
|
||||
|
||||
\func{virtual bool}{OnCreate}{\param{const wxString\& }{path}, \param{long}{ flags}}
|
||||
|
||||
Called just after the document object is created to give it a chance
|
||||
to initialize itself. The default implementation uses the
|
||||
template associated with the document to create an initial view.
|
||||
If this function returns FALSE, the document is deleted.
|
||||
|
||||
\membersection{wxDocument::OnCreateCommandProcessor}
|
||||
|
||||
\func{virtual wxCommandProcessor*}{OnCreateCommandProcessor}{\void}
|
||||
|
||||
Override this function if you want a different (or no) command processor
|
||||
to be created when the document is created. By default, it returns
|
||||
an instance of wxCommandProcessor.
|
||||
|

\func{virtual bool}{OnNewDocument}{\void}
|
||||
|
||||
The default implementation calls OnSaveModified and DeleteContents, makes a default title for the
|
||||
document, and notifies the views that the filename (in fact, the title) has changed.
|
||||
|
||||
\membersection{wxDocument::OnOpenDocument}
|
||||
|
||||
\func{virtual bool}{OnOpenDocument}{\param{const wxString\& }{filename}}
|
||||
|
||||
Constructs an input file stream for the given filename (which must not be empty),
|
||||
and calls LoadObject. If LoadObject returns TRUE, the document is set to
|
||||
unmodified; otherwise, an error message box is displayed. The document's
|
||||
views are notified that the filename has changed, to give windows an opportunity
|
||||
to update their titles. All of the document's views are then updated.
|
||||
|
||||
\membersection{wxDocument::OnSaveDocument}
|
||||
|
||||
\func{virtual bool}{OnSaveDocument}{\param{const wxString\& }{filename}}
|
||||
|
||||
Constructs an output file stream for the given filename (which must not be empty),
|
||||
and calls SaveObject. If SaveObject returns TRUE, the document is set to
|
||||
unmodified; otherwise, an error message box is displayed.
|
||||
|
||||
\membersection{wxDocument::OnSaveModified}
|
||||
|
||||
\func{virtual bool}{OnSaveModified}{\void}
|
||||
|
||||
If the document has been modified, prompts the user to ask if the changes should
|
||||
be changed. If the user replies Yes, the Save function is called. If No, the
|
||||
document is marked as unmodified and the function succeeds. If Cancel, the
|
||||
function fails.
|
||||
|
||||
\membersection{wxDocument::RemoveView}
|
||||
|
||||
\func{virtual bool}{RemoveView}{\param{wxView* }{view}}
|
||||
|
||||
Removes the view from the document's list of views, and calls OnChangedViewList.
|
||||
|
||||
\membersection{wxDocument::Save}
|
||||
|
||||
\func{virtual bool}{Save}{\void}
|
||||
|
||||
Saves the document by calling OnSaveDocument if there is an associated filename,
|
||||
or SaveAs if there is no filename.
|
||||
|
||||
\membersection{wxDocument::SaveAs}
|
||||
|
||||
\func{virtual bool}{SaveAs}{\void}
|
||||
|
||||
Prompts the user for a file to save to, and then calls OnSaveDocument.
|
||||
|
||||
\membersection{wxDocument::SaveObject}
|
||||
|
||||
\func{virtual ostream\&}{SaveObject}{\param{ostream\& }{stream}}
|
||||
|
||||
\func{virtual wxOutputStream\&}{SaveObject}{\param{wxOutputStream\& }{stream}}
|
||||
|
||||
Override this function and call it from your own SaveObject before
|
||||
streaming your own data. SaveObject is called by the framework
|
||||
automatically when the document contents need to be saved.
|
||||
|
||||
Note that only one of these forms exists, depending on how wxWindows
|
||||
was configured.
|
||||
|
||||
\membersection{wxDocument::SetCommandProcessor}
|
||||
|
||||
\func{virtual void}{SetCommandProcessor}{\param{wxCommandProcessor *}{processor}}
|
||||
|
||||
Sets the command processor to be used for this document. The document will then be responsible
|
||||
for its deletion. Normally you should not call this; override OnCreateCommandProcessor
|
||||
instead.
|
||||
|
||||
See \helpref{wxCommandProcessor}{wxcommandprocessor}.

||||
\membersection{wxDocument::SetDocumentName}
|
||||
|
||||
\func{void}{SetDocumentName}{\param{const wxString\& }{name}}
|
||||
|
||||
Sets the document type name for this document. See the comment for \helpref{documentTypeName}{documenttypename}.
|

||||
\membersection{wxDocument::SetDocumentTemplate}
|
||||
|
||||
\func{void}{SetDocumentTemplate}{\param{wxDocTemplate* }{templ}}
|
||||
|
||||
Sets the pointer to the template that created the document. Should only be called by the
|
||||
framework.
|

|
||||
\membersection{wxDocument::SetFilename}
|
||||
|
||||
\func{void}{SetFilename}{\param{const wxString\& }{filename}, \param{bool}{ notifyViews = FALSE}}
|
||||
|
||||
Sets the filename for this document. Usually called by the framework.
|
||||
|
||||
If {\it notifyViews} is TRUE, wxView::OnChangeFilename is called for all views.
|
||||
|
||||
\membersection{wxDocument::SetTitle}
|
||||
|
||||
\func{void}{SetTitle}{\param{const wxString\& }{title}}
|
||||
|
||||
Sets the title for this document. The document title is used for an associated
|
||||
frame (if any), and is usually constructed by the framework from
|
||||
the filename.

\section{\class{wxDragImage}}\label{wxdragimage}
|

|

This class is used when you wish to drag an object on the screen,
|
||||
and a simple cursor is not enough.
|
||||
|
||||
On Windows, the WIN32 API is used to do achieve smooth dragging. On other platforms,
|
||||
wxGenericDragImage is used. Applications may also prefer to use
|
||||
wxGenericDragImage on Windows, too.
|
||||
|
||||
\pythonnote{wxPython uses wxGenericDragImage on all platforms, but
|
||||
uses the wxDragImage name.}
|
||||
|
||||
To use this class, when you wish to start dragging an image, create a wxDragImage
|
||||
object and store it somewhere you can access it as the drag progresses.
|
||||
Call BeginDrag to start, and EndDrag to stop the drag. To move the image,
|
||||
initially call Show and then Move. If you wish to update the screen contents
|
||||
during the drag (for example, highlight an item as in the dragimag sample), first call Hide,
|
||||
update the screen, call Move, and then call Show.
|
||||
|
||||
You can drag within one window, or you can use full-screen dragging
|
||||
either across the whole screen, or just restricted to one area
|
||||
of the screen to save resources. If you want the user to drag between
|
||||
two windows, then you will need to use full-screen dragging.
|
||||
|
||||
If you wish to draw the image yourself, use wxGenericDragImage and
|
||||
override \helpref{wxDragImage::DoDrawImage}{wxdragimagedodrawimage} and
|
||||
\helpref{wxDragImage::GetImageRect}{wxdragimagegetimagerect}.
|
||||
|

|
||||
|
||||
\func{bool}{BeginDrag}{\param{const wxPoint\& }{hotspot}, \param{wxWindow* }{window}, \param{bool}{ fullScreen = FALSE}, \param{wxRect*}{ rect = NULL}}
|
||||
|
||||
Start dragging the image, in a window or full screen.
|
||||
|
||||
\func{bool}{BeginDrag}{\param{const wxPoint\& }{hotspot}, \param{wxWindow* }{window}, \param{wxWindow*}{ boundingWindow}}
|
||||
|
||||
Start dragging the image, using the first window to capture the mouse and the second
|
||||
to specify the bounding area. This form is equivalent to using the first form,
|
||||
but more convenient than working out the bounding rectangle explicitly.
|
||||
|
||||
You need to then call \helpref{wxDragImage::Show}{wxdragimageshow}
|
||||
and \helpref{wxDragImage::Move}{wxdragimagemove} to show the image on the screen.
|
||||
|
||||
Call \helpref{wxDragImage::EndDrag}{wxdragimageenddrag} when the drag has finished.
|
||||
|
||||
Note that this call automatically calls CaptureMouse.
|
||||
|
||||
\wxheading{Parameters}
|
||||
|
||||
\docparam{hotspot}{The location of the drag position relative to the upper-left corner
|
||||
of the image.}
|
||||
|
||||
\docparam{window}{The window that captures the mouse, and within which the dragging
|
||||
is limited unless {\it fullScreen} is TRUE.}
|
||||
|
||||
\docparam{boundingWindow}{In the second form of the function, specifies the
|
||||
area within which the drag occurs.}
|
||||
|
||||
\docparam{fullScreen}{If TRUE, specifies that the drag will be visible over the full
|
||||
screen, or over as much of the screen as is specified by {\it rect}. Note that the mouse will
|
||||
still be captured in {\it window}.}
|
||||
|
||||
\docparam{rect}{If non-NULL, specifies the rectangle (in screen coordinates) that
|
||||
bounds the dragging operation. Specifying this can make the operation more efficient
|
||||
by cutting down on the area under consideration, and it can also make a visual difference
|
||||
since the drag is clipped to this area.}

\membersection{wxDragImage::DoDrawImage}\label{wxdragimagedodrawimage}
|
||||
|

\func{virtual bool}{DoDrawImage}{\param{wxDC\&}{ dc}, \param{const wxPoint\&}{ pos}}
|
||||
|
||||
Draws the image on the device context with top-left corner at the given position.
|
||||
|
||||
This function is only available with wxGenericDragImage, to allow applications to
|
||||
draw their own image instead of using an actual bitmap. If you override this function,
|
||||
you must also override \helpref{wxDragImage::GetImageRect}{wxdragimagegetimagerect}.
|
||||
|
||||
\membersection{wxDragImage::EndDrag}\label{wxdragimageenddrag}
|
||||
|
||||
\func{bool}{EndDrag}{\void}
|
||||
|
||||
Call this when the drag has finished.
|
||||
|
||||
Note that this call automatically calls ReleaseMouse.
|
||||
|
||||
\membersection{wxDragImage::GetImageRect}\label{wxdragimagegetimagerect}
|
||||
|
||||
\constfunc{virtual wxRect}{GetImageRect}{\param{const wxPoint\&}{ pos}}
|
||||
|
||||
Returns the rectangle enclosing the image, assuming that the image is drawn with its
|
||||
top-left corner at the given point.
|
||||
|
||||
This function is available in wxGenericDragImage only, and may be overridden (together with
|
||||
\helpref{wxDragImage::DoDrawImage}{wxdragimagedodrawimage}) to provide a virtual drawing capability.
|
||||
|
||||
\membersection{wxDragImage::Hide}\label{wxdragimagehide}
|
||||
|
||||
\func{bool}{Hide}{\void}
|
||||
|
||||
Hides the image. You may wish to call this before updating the window
|
||||
contents (perhaps highlighting an item). Then call \helpref{wxDragImage::Move}{wxdragimagemove}
|
||||
and \helpref{wxDragImage::Show}{wxdragimageshow}.
|
||||
|
||||
\membersection{wxDragImage::Move}\label{wxdragimagemove}
|
||||
|
||||
\func{bool}{Move}{\param{const wxPoint\& }{pt}}
|
||||
|
||||
Call this to move the image to a new position. The image will only be shown if
|
||||
\helpref{wxDragImage::Show}{wxdragimageshow} has been called previously (for example
|
||||
at the start of the drag).
|
||||
|
||||
{\it pt} is the position in client coordinates (relative to the window specified in BeginDrag).
|
||||
|
||||
You can move the image either when the image is hidden or shown, but in general dragging
|
||||
will be smoother if you move the image when it is shown.
|
||||
|
||||
\membersection{wxDragImage::Show}\label{wxdragimageshow}
|
||||
|
||||
\func{bool}{Show}{\void}
|
||||
|
||||
Shows the image. Call this at least once when dragging.
|
||||
|
||||
\membersection{wxDragImage::UpdateBackingFromWindow}\label{wxdragimageupdatebackingfromwindow}
|
||||
|
||||
\constfunc{bool}{UpdateBackingFromWindow}{\param{wxDC\&}{ windowDC}, \param{wxMemoryDC\&}{ destDC},
|
||||
\param{const wxRect\&}{ sourceRect}, \param{const wxRect\&}{ destRect}}
|
||||
|
||||
Override this if you wish to draw the window contents to the backing bitmap
|
||||
yourself. This can be desirable if you wish to avoid flicker by not having to
|
||||
redraw the updated window itself just before dragging, which can cause a flicker just
|
||||
as the drag starts. Instead, paint the drag image's backing bitmap to show the appropriate
|
||||
graphic {\it minus the objects to be dragged}, and leave the window itself to be updated
|
||||
by the drag image. This can provide eerily smooth, flicker-free drag behaviour.
|
||||
|
||||
The default implementation copies the window contents to the backing bitmap. A new
|
||||
implementation will normally copy information from another source, such as from its
|
||||
own backing bitmap if it has one, or directly from internal data structures.
|
||||

\section{\class{wxDropTarget}}\label{wxdroptarget}
|

|

This class represents a target for a drag and drop operation. A \helpref{wxDataObject}{wxdataobject}
|
||||
can be associated with it and by default, this object will be filled with the data from the
|
||||
drag source, if the data formats supported by the data object match the drag source data
|
||||
format.
|
||||
|
||||
There are various virtual handler functions defined in this class which may be overridden
|
||||
to give visual feedback or react in a more fine-tuned way, e.g. by not accepting data on
|
||||
the whole window area, but only a small portion of it. The normal sequence of calls is
|
||||
\helpref{OnEnter}{wxdroptargetonenter}, possibly many times \helpref{OnDragOver}{wxdroptargetondragover},
|

\helpref{OnDrop}{wxdroptargetondrop} and finally \helpref{OnData}{wxdroptargetondata}.

\func{bool}{Init}{\param{wxFontEncoding }{input\_enc}, \param{wxFontEncoding }{output\_enc}, \param{int }{method = wxCONVERT\_STRICT}}
|
||||
|

Initialize conversion. Both output or input encoding may
|
||||
be wxFONTENCODING\_UNICODE, but only if wxUSE\_ENCODING is set to 1.
|
||||
All subsequent calls to \helpref{Convert()}{wxencodingconverterconvert}
|
||||
will interpret its argument
|

as a string in {\it input\_enc} encoding and will output string in
|
||||
{\it output\_enc} encoding.
|
||||
You must call this method before calling Convert. You may call
|
||||
it more than once in order to switch to another conversion.
|
||||
{\it Method} affects behaviour of Convert() in case input character
|
||||
cannot be converted because it does not exist in output encoding:

||||
|
||||
\begin{twocollist}\itemsep=0pt

Equivalence is defined in terms of convertibility:
|
||||
two encodings are equivalent if you can convert text between
|
||||
then without losing information (it may - and will - happen
|
||||
that you lose special chars like quotation marks or em-dashes
|
||||
but you shouldn't lose any diacritics and language-specific
|
||||
characters when converting between equivalent encodings).
|
||||
|
||||
Remember that this function does {\bf NOT} check for presence of
|
||||
fonts in system. It only tells you what are most suitable
|
||||
encodings. (It usually returns only one encoding.)

|

|
||||
\begin{itemize}\itemsep=0pt
|

\item Note that argument {\it enc} itself may be present in the returned array,

||||
so that you can, as a side-effect, detect whether the
|

encoding is native for this platform or not.
|
||||
\item \helpref{Convert}{wxencodingconverterconvert} is not limited to
|
||||
converting between equivalent encodings, it can convert between two arbitrary
|
||||
encodings.
|
||||
\item If {\it enc} is present in the returned array, then it is {\bf always} the first
|

item of it.

\section{\class{wxEraseEvent}}\label{wxeraseevent}
|
||||
|
||||
An erase event is sent when a window's background needs to be repainted.
|
||||
|
||||
On some platforms, such as GTK+, this event is simulated (simply generated just before the
|
||||
paint event) and may cause flicker. It is therefore recommended that
|
||||
you set the text background colour explicitly in order to prevent flicker.
|
||||
The default background colour under GTK+ is grey.
|
||||
|
||||
To intercept this event, use the EVT\_ERASE\_BACKGROUND macro in an event table definition.
|
||||
|
||||
You must call wxEraseEvent::GetDC and use the returned device context if it is non-NULL.
|
||||
If it is NULL, create your own temporary wxClientDC object.

Returns a copy of the event.

Any event that is posted to the wxWindows event system for later action (via
|
||||
\helpref{wxEvtHandler::AddPendingEvent}{wxevthandleraddpendingevent} or
|
||||
\helpref{wxPostEvent}{wxpostevent}) must implement this method. All wxWindows
|

events fully implement this method, but any derived events implemented by the
|
||||
user should also implement this method just in case they (or some event
|
||||
derived from them) are ever posted.
|
||||
|
||||
All wxWindows events implement a copy constructor, so the easiest way of
|
||||
implementing the Clone function is to implement a copy constructor for
|
||||
a new event (call it MyEvent) and then define the Clone function like this:

wxEvent *Clone(void) const { return new MyEvent(*this); }

This function posts an event to be processed later.

\wxheading{Parameters}
|
||||
|
||||
\docparam{event}{Event to add to process queue.}
|
||||
|
||||
\wxheading{Remarks}
|
||||
|
||||
The difference between sending an event (using the
|
||||
\helpref{ProcessEvent}{wxevthandlerprocessevent} method) and posting it is
|
||||
that in the first case the event is processed before the function returns,
|
||||
while in the second case, the function returns immediately and the event will
|
||||
be processed sometime later (usually during the next event loop iteration).
|
||||
|
||||
A copy of {\it event} is made by the function, so the original can be deleted
|
||||
as soon as function returns (it is common that the original is created on the
|
||||
stack). This requires that the \helpref{wxEvent::Clone}{wxeventclone} method
|
||||
be implemented by {\it event} so that it can be duplicated and stored until
|
||||
it gets processed.
|
||||
|
||||
This is also the method to call for inter-thread communication---it will
|
||||
post events safely between different threads which means that this method is
|
||||
thread-safe by using critical sections where needed. In a multi-threaded
|
||||
program, you often need to inform the main GUI thread about the status of
|
||||
other working threads and such notification should be done using this method.
|
||||
|
||||
This method automatically wakes up idle handling if the underlying window
|
||||
system is currently idle and thus would not send any idle events. (Waking
|
||||
up idle handling is done calling \helpref{::wxWakeUpIdle}{wxwakeupidle}.)

\wxheading{Return value}

TRUE if a suitable event handler function was found and executed, and the function did not

call \helpref{wxEvent::Skip}{wxeventskip}.
|
||||
|
||||
\wxheading{Remarks}
|
||||
|
||||
Normally, your application would not call this function: it is called in the wxWindows
|
||||
implementation to dispatch incoming user interface events to the framework (and application).
|
||||
|
||||
However, you might need to call it if implementing new functionality (such as a new control) where
|
||||
you define new event types, as opposed to allowing the user to override virtual functions.
|
||||
|
||||
An instance where you might actually override the {\bf ProcessEvent} function is where you want
|
||||
to direct event processing to event handlers not normally noticed by wxWindows. For example,
|
||||
in the document/view architecture, documents and views are potential event handlers.
|
||||
When an event reaches a frame, {\bf ProcessEvent} will need to be called on the associated
|
||||
document and view in case event handler functions are associated with these objects.
|
||||
The property classes library (wxProperty) also overrides {\bf ProcessEvent} for similar reasons.
|
||||
|
||||
The normal order of event table searching is as follows:
|
||||
|
||||
\begin{enumerate}\itemsep=0pt
|
||||
\item If the object is disabled (via a call to \helpref{wxEvtHandler::SetEvtHandlerEnabled}{wxevthandlersetevthandlerenabled})
|
||||
the function skips to step (6).
|
||||
\item If the object is a wxWindow, {\bf ProcessEvent} is recursively called on the window's\rtfsp
|
||||
\helpref{wxValidator}{wxvalidator}. If this returns TRUE, the function exits.
|
||||
\item {\bf SearchEventTable} is called for this event handler. If this fails, the base
|
||||
class table is tried, and so on until no more tables exist or an appropriate function was found,
|
||||
in which case the function exits.
|
||||
\item The search is applied down the entire chain of event handlers (usually the chain has a length
|
||||
of one). If this succeeds, the function exits.
|
||||
\item If the object is a wxWindow and the event is a wxCommandEvent, {\bf ProcessEvent} is
|
||||
recursively applied to the parent window's event handler. If this returns TRUE, the function exits.
|
||||
\item Finally, {\bf ProcessEvent} is called on the wxApp object.

||||

|

\wxheading{Return value}
|
||||
|

TRUE if a suitable event handler function was found and executed, and the function did not
|
||||
call \helpref{wxEvent::Skip}{wxeventskip}.
|
||||
|
||||
\wxheading{Remarks}
|
||||
|
||||
This function looks through the object's event table and tries to find an entry
|
||||
that will match the event.
|
||||
|
||||
An entry will match if:
|
||||
|
||||
\begin{enumerate}\itemsep=0pt
|
||||
\item The event type matches, and
|
||||
\item the identifier or identifier range matches, or the event table entry's identifier is zero.
|
||||
\end{enumerate}
|
||||
|
||||
If a suitable function is called but calls \helpref{wxEvent::Skip}{wxeventskip}, this function will
|
||||
fail, and searching will continue.

\section{\class{wxExpr}}\label{wxexpr}
|
||||
|
||||
The {\bf wxExpr} class is the building brick of expressions similar to Prolog
|
||||
clauses, or objects. It can represent an expression of type long integer, float, string, word,
|
||||
or list, and lists can be nested.

||||

\membersection{wxExpr::wxExpr}\label{wxexprconstr}
|
||||
|
||||
\func{}{wxExpr}{\param{const wxString\&}{functor}}
|
||||
|
||||
Construct a new clause with this form, supplying the functor name. A clause is an object
|
||||
that will appear in the data file, with a list of attribute/value pairs.
|
||||
|
||||
\func{}{wxExpr}{\param{wxExprType}{ type}, \param{const wxString\&}{ wordOrString = ``"}}
|
||||
|
||||
Construct a new empty list, or a word (will be output with no quotes), or a string, depending on the
|
||||
value of {\it type}.
|
||||
|
||||
{\it type} can be {\bf wxExprList}, {\bf wxExprWord}, or {\bf wxExprString}. If {\it type} is wxExprList,
|
||||
the value of {\it wordOrString} will be ignored.
|
||||
|
||||
\func{}{wxExpr}{\param{long}{ value}}
|
||||
|
||||
Construct an integer expression.
|
||||
|
||||
\func{}{wxExpr}{\param{float}{ value}}
|
||||
|
||||
Construct a floating point expression.
|
||||
|
||||
\func{}{wxExpr}{\param{wxList* }{value}}
|
||||
|
||||
Construct a list expression. The list's nodes' data should
|
||||
themselves be {\bf wxExpr}s.
|
||||
|
||||
wxExpr no longer uses the {\bf wxList} internally,
|
||||
so this constructor turns the list into its internal
|
||||
format (assuming a non-nested list) and then deletes the supplied
|
||||
list.
|
||||
|
||||
\membersection{wxExpr::\destruct{wxExpr}}
|
||||
|
||||
\func{}{\destruct{wxExpr}}{\void}
|
||||
|
||||
Destructor.
|
||||
|
||||
\membersection{wxExpr::AddAttributeValue}\label{wxexpraddattributevalue}
|
||||
|
||||
Use these on clauses ONLY. Note that the functions for adding strings
|
||||
and words must be differentiated by function name which is why
|
||||
they are missing from this group (see \helpref{wxExpr::AddAttributeValueString}{wxexpraddattributevaluestring} and
|
||||
\rtfsp\helpref{wxExpr::AddAttributeValueWord}{wxexpraddattributevalueword}).
|
||||
|
||||
\func{void}{AddAttributeValue}{\param{const wxString\&}{ attribute}, \param{float }{value}}
|
||||
|
||||
Adds an attribute and floating point value pair to the clause.
|
||||
|
||||
\func{void}{AddAttributeValue}{\param{const wxString\&}{ attribute}, \param{long }{value}}
|
||||
|
||||
Adds an attribute and long integer value pair to the clause.
|
||||
|
||||
\func{void}{AddAttributeValue}{\param{const wxString\&}{ attribute}, \param{wxList* }{value}}
|
||||
|
||||
Adds an attribute and list value pair to the clause, converting the list into
|
||||
internal form and then deleting {\bf value}. Note that the list should not contain
|
||||
nested lists (except if in internal {\bf wxExpr} form.)
|
||||
|
||||
\func{void}{AddAttributeValue}{\param{const wxString\&}{ attribute}, \param{wxExpr* }{value}}
|
||||
|
||||
Adds an attribute and wxExpr value pair to the clause. Do not delete\rtfsp
|
||||
{\it value} once this function has been called.
|
||||
|
||||
\membersection{wxExpr::AddAttributeValueString}\label{wxexpraddattributevaluestring}
|
||||
|
||||
\func{void}{AddAttributeValueString}{\param{const wxString\&}{ attribute}, \param{const wxString\&}{ value}}
|
||||
|
||||
Adds an attribute and string value pair to the clause.
|
||||
|
||||
\membersection{wxExpr::AddAttributeValueStringList}\label{wxexpraddattributevaluestringlist}
|
||||
|
||||
\func{void}{AddAttributeValueStringList}{\param{const wxString\&}{ attribute}, \param{wxList* }{value}}
|
||||
|
||||
Adds an attribute and string list value pair to the clause.
|
||||
|
||||
Note that the list passed to this function is a list of strings, NOT a list
|
||||
of {\bf wxExpr}s; it gets turned into a list of {\bf wxExpr}s
|
||||
automatically. This is a convenience function, since lists of strings
|
||||
are often manipulated in C++.
|
||||
|
||||
\membersection{wxExpr::AddAttributeValueWord}\label{wxexpraddattributevalueword}
|
||||
|
||||
\func{void}{AddAttributeValueWord}{\param{const wxString\&}{ attribute}, \param{const wxString\&}{ value}}
|
||||
|
||||
Adds an attribute and word value pair to the clause.
|
||||
|
||||
\membersection{wxExpr::Append}\label{wxexprappend}
|
||||
|
||||
\func{void}{Append}{\param{wxExpr*}{ value}}
|
||||
|
||||
Append the {\bf value} to the end of the list. `this' must be a list.
|
||||
|
||||
\membersection{wxExpr::Arg}\label{wxexprarg}
|
||||
|
||||
\constfunc{wxExpr* }{Arg}{\param{wxExprType}{ type}, \param{int}{ n}}
|
||||
|
||||
Get nth arg of the given clause (starting from 1). NULL is returned if
|
||||
the expression is not a clause, or {\it n} is invalid, or the given type
|
||||
does not match the actual type. See also \helpref{wxExpr::Nth}{wxexprnth}.
|
||||
|
||||
\membersection{wxExpr::Insert}\label{wxexprinsert}
|
||||
|
||||
\func{void}{Insert}{\param{wxExpr* }{value}}
|
||||
|
||||
Insert the {\bf value} at the start of the list. `this' must be a list.
|
||||
|
||||
\membersection{wxExpr::GetAttributeValue}\label{wxexprgetattributevalue}
|
||||
|
||||
These functions are the easiest way to retrieve attribute values, by
|
||||
passing a pointer to variable. If the attribute is present, the
|
||||
variable will be filled with the appropriate value. If not, the
|
||||
existing value is left alone. This style of retrieving attributes
|
||||
makes it easy to set variables to default values before calling these
|
||||
functions; no code is necessary to check whether the attribute is
|
||||
present or not.
|
||||
|
||||
\constfunc{bool}{GetAttributeValue}{\param{const wxString\&}{ attribute}, \param{wxString\&}{ value}}
|
||||
|
||||
Retrieve a string (or word) value.
|
||||
|
||||
\constfunc{bool}{GetAttributeValue}{\param{const wxString\&}{ attribute}, \param{float\& }{value}}
|
||||
|
||||
Retrieve a floating point value.
|
||||
|
||||
\constfunc{bool}{GetAttributeValue}{\param{const wxString\&}{ attribute}, \param{int\& }{value}}
|
||||
|
||||
Retrieve an integer value.
|
||||
|
||||
\constfunc{bool}{GetAttributeValue}{\param{const wxString\&}{ attribute}, \param{long\& }{value}}
|
||||
|
||||
Retrieve a long integer value.
|
||||
|
||||
\constfunc{bool}{GetAttributeValue}{\param{const wxString\&}{ attribute}, \param{wxExpr**}{ value}}
|
||||
|
||||
Retrieve a wxExpr pointer.
|
||||
|
||||
\membersection{wxExpr::GetAttributeValueStringList}\label{wxexprgetattributestringlist}
|
||||
|
||||
\constfunc{void}{GetAttributeValueStringList}{\param{const wxString\&}{attribute}, \param{wxList* }{value}}
|
||||
|
||||
Use this on clauses ONLY. See above for comments on this style of
|
||||
attribute value retrieval. This function expects to receive a pointer to
|
||||
a new list (created by the calling application); it will append strings
|
||||
to the list if the attribute is present in the clause.
|
||||
|
||||
\membersection{wxExpr::AttributeValue}\label{wxexprattributevalue}
|
||||
|
||||
\constfunc{wxExpr*}{AttributeValue}{\param{const wxString\&}{ word}}
|
||||
|
||||
Use this on clauses ONLY. Searches the clause for an attribute
|
||||
matching {\it word}, and returns the value associated with it.
|
||||
|
||||
\membersection{wxExpr::Copy}\label{wxexprcopy}
|
||||
|
||||
\constfunc{wxExpr*}{Copy}{\void}
|
||||
|
||||
Recursively copies the expression, allocating new storage space.
|
||||
|
||||
\membersection{wxExpr::DeleteAttributeValue}\label{wxexprdeletattributevalue}
|
||||
|
||||
\func{void}{DeleteAttributeValue}{\param{const wxString\&}{ attribute}}
|
||||
|
||||
Use this on clauses only. Deletes the attribute and its value (if any) from the
|
||||
clause.
|
||||
|
||||
\membersection{wxExpr::Functor}\label{wxexprfunctor}
|
||||
|
||||
\constfunc{wxString}{Functor}{\void}
|
||||
|
||||
Use this on clauses only. Returns the clause's functor (object name).
|
||||
|
||||
\membersection{wxExpr::GetClientData}\label{wxexprgetclientdata}
|
||||
|
||||
\constfunc{wxObject*}{GetClientData}{\void}
|
||||
|
||||
Retrieve arbitrary data stored with this clause. This can be useful when
|
||||
reading in data for storing a pointer to the C++ object, so when another
|
||||
clause makes a reference to this clause, its C++ object can be retrieved.
|
||||
See \helpref{wxExpr::SetClientData}{wxexprsetclientdata}.
|
||||
|
||||
\membersection{wxExpr::GetFirst}\label{wxexprgetfirst}
|
||||
|
||||
\constfunc{wxExpr*}{GetFirst}{\void}
|
||||
|
||||
If this is a list expression (or clause), gets the first element in the list.
|
||||
|
||||
See also \helpref{wxExpr::GetLast}{wxexprgetlast}, \helpref{wxExpr::GetNext}{wxexprgetnext}, \helpref{wxExpr::Nth}{wxexprnth}.
|
||||
|
||||
\membersection{wxExpr::GetLast}\label{wxexprgetlast}
|
||||
|
||||
\constfunc{wxExpr*}{GetLast}{\void}
|
||||
|
||||
If this is a list expression (or clause), gets the last element in the list.
|
||||
|
||||
See also \helpref{wxExpr::GetFirst}{wxexprgetfirst}, \helpref{wxExpr::GetNext}{wxexprgetnext}, \helpref{wxExpr::Nth}{wxexprnth}.
|
||||
|
||||
\membersection{wxExpr::GetNext}\label{wxexprgetnext}
|
||||
|
||||
\constfunc{wxExpr*}{GetNext}{\void}
|
||||
|
||||
If this is a node in a list (any wxExpr may be a node in a list), gets the
|
||||
next element in the list.
|
||||
|
||||
See also \helpref{wxExpr::GetFirst}{wxexprgetfirst}, \helpref{wxExpr::GetLast}{wxexprgetlast}, \helpref{wxExpr::Nth}{wxexprnth}.
|
||||
|
||||
\membersection{wxExpr::IntegerValue}\label{wxexprintegervalue}
|
||||
|
||||
\constfunc{long}{IntegerValue}{\void}
|
||||
|
||||
Returns the integer value of the expression.
|
||||
|
||||
\membersection{wxExpr::Nth}\label{wxexprnth}
|
||||
|
||||
\constfunc{wxExpr*}{Nth}{\param{int}{ n}}
|
||||
|
||||
Get nth arg of the given list expression (starting from 0). NULL is returned if
|
||||
the expression is not a list expression, or {\it n} is invalid. See also \helpref{wxExpr::Arg}{wxexprarg}.
|
||||
|
||||
Normally, you would use attribute-value pairs to add and retrieve data
|
||||
from objects (clauses) in a data file. However, if the data gets complex,
|
||||
you may need to store attribute values as lists, and pick them apart
|
||||
yourself.
|
||||
|
||||
\membersection{wxExpr::RealValue}\label{wxexprrealvalue}
|
||||
|
||||
\constfunc{float}{RealValue}{\void}
|
||||
|
||||
Returns the floating point value of the expression.
|
||||
|
||||
\membersection{wxExpr::SetClientData}\label{wxexprsetclientdata}
|
||||
|
||||
\func{void}{SetClientData}{\param{wxObject *}{data}}
|
||||
|
||||
Associate arbitrary data with this clause. This can be useful when
|
||||
reading in data for storing a pointer to the C++ object, so when another
|
||||
clause makes a reference to this clause, its C++ object can be retrieved.
|
||||
See \helpref{wxExpr::GetClientData}{wxexprgetclientdata}.
|
||||
|
||||
\membersection{wxExpr::StringValue}\label{wxexprstringvalue}
|
||||
|
||||
\constfunc{wxString}{StringValue}{\void}
|
||||
|
||||
Returns the string value of the expression.
|
||||
|
||||
\membersection{wxExpr::Type}\label{wxexprtype}
|
||||
|
||||
\constfunc{wxExprType}{Type}{\void}
|
||||
|
||||
Returns the type of the expression. {\bf wxExprType} is defined as follows:
|
||||
|
||||
\begin{verbatim}
|
||||
typedef enum {
|
||||
wxExprNull,
|
||||
wxExprInteger,
|
||||
wxExprReal,
|
||||
wxExprWord,
|
||||
wxExprString,
|
||||
wxExprList
|
||||
} wxExprType;
|
||||
\end{verbatim}
|
||||
|
||||
\membersection{wxExpr::WordValue}\label{wxexprwordvalue}
|
||||
|
||||
\constfunc{wxString}{WordValue}{\void}
|
||||
|
||||
Returns the word value of the expression.
|
||||
|
||||
\membersection{wxExpr::WriteClause}\label{wxexprwriteprologclause}
|
||||
|
||||
\func{void}{WriteClause}{\param{FILE *}{ stream}}
|
||||
|
||||
Writes the clause to the given stream in Prolog format. Not normally needed, since
|
||||
the whole {\bf wxExprDatabase} will usually be written at once. The format is:
|
||||
functor, open parenthesis, list of comma-separated expressions, close parenthesis,
|
||||
full stop.
|
||||
|
||||
\membersection{wxExpr::WriteExpr}\label{wxexprwriteexpr}
|
||||
|
||||
\func{void}{WriteExpr}{\param{FILE *}{ stream}}
|
||||
|
||||
Writes the expression (not clause) to the given stream in Prolog
|
||||
format. Not normally needed, since the whole {\bf wxExprDatabase} will
|
||||
usually be written at once. Lists are written in square bracketed,
|
||||
comma-delimited format.
|
||||
|
||||
\membersection{Functions and macros}
|
||||
|
||||
Below are miscellaneous functions and macros associated with wxExpr objects.
|
||||
|
||||
\func{bool}{wxExprIsFunctor}{\param{wxExpr *}{expr}, \param{const wxString\&}{ functor}}
|
||||
|
||||
Checks that the functor of {\it expr} is {\it functor}.
|
||||
|
||||
\func{void}{wxExprCleanUp}{\void}
|
||||
|
||||
Cleans up the wxExpr system (YACC/LEX buffers) to avoid memory-checking warnings as the program exits.
|
||||
|
||||
\begin{verbatim}
|
||||
#define wxMakeInteger(x) (new wxExpr((long)x))
|
||||
#define wxMakeReal(x) (new wxExpr((float)x))
|
||||
#define wxMakeString(x) (new wxExpr(PrologString, x))
|
||||
#define wxMakeWord(x) (new wxExpr(PrologWord, x))
|
||||
#define wxMake(x) (new wxExpr(x))
|
||||
\end{verbatim}
|
||||
|

Macros to help make wxExpr objects.
|
||||
|
||||
\section{\class{wxExprDatabase}}\label{wxexprdatabase}
|
||||
|
||||
The {\bf wxExprDatabase} class represents a database, or list,
|
||||
of Prolog-like expressions. Instances of this class are used for reading,
|
||||
writing and creating data files.

\membersection{wxExprDatabase::wxExprDatabase}\label{wxexprdatabaseconstr}
|
||||
|
||||
\func{void}{wxExprDatabase}{\param{proioErrorHandler}{ handler = 0}}
|
||||
|
||||
Construct a new, unhashed database, with an optional error handler. The
|
||||
error handler must be a function returning a bool and taking an integer and a string
|
||||
argument. When an error occurs when reading or writing a database, this function is
|
||||
called. The error is given as the first argument (currently one of WXEXPR\_ERROR\_GENERAL,
|
||||
WXEXPR\_ERROR\_SYNTAX) and an error message is given as the second argument. If FALSE
|
||||
is returned by the error handler, processing of the wxExpr operation stops.
|
||||
|
||||
Another way of handling errors is simply to call \helpref{wxExprDatabase::GetErrorCount}{wxexprdatabasegeterrorcount} after
|
||||
the operation, to check whether errors have occurred, instead of installing an error handler.
|
||||
If the error count is more than zero, \helpref{wxExprDatabase::Write}{wxexprdatabasewrite} and
|
||||
\rtfsp\helpref{wxExprDatabase::Read}{wxexprdatabaseread} will return FALSE to
|
||||
the application.
|
||||
|
||||
For example:
|
||||
|
||||
\begin{verbatim}
|
||||
bool myErrorHandler(int err, chat *msg)
|
||||
{
|
||||
if (err == WXEXPR_ERROR_SYNTAX)
|
||||
{
|
||||
wxMessageBox(msg, "Syntax error");
|
||||
}
|
||||
return FALSE;
|
||||
}
|
||||
|
||||
wxExprDatabase database(myErrorHandler);
|
||||
\end{verbatim}
|
||||
|
||||
\func{}{wxExprDatabase}{\param{wxExprType}{ type}, \param{const wxString\&}{attribute},
|
||||
\rtfsp\param{int}{ size = 500}, \param{proioErrorHandler}{ handler = 0}}
|
||||
|
||||
Construct a new database hashed on a combination of the clause functor and
|
||||
a named attribute (often an integer identification).
|
||||
|
||||
See above for an explanation of the error handler.
|
||||
|
||||
\membersection{wxExprDatabase::\destruct{wxExprDatabase}}
|
||||
|
||||
\func{}{\destruct{wxExprDatabase}}{\void}
|
||||
|
||||
Delete the database and contents.
|
||||
|
||||
\membersection{wxExprDatabase::Append}\label{wxexprdatabaseappend}
|
||||
|
||||
\func{void}{Append}{\param{wxExpr* }{clause}}
|
||||
|
||||
Append a clause to the end of the database. If the database is hashing,
|
||||
the functor and a user-specified attribute will be hashed upon, giving the
|
||||
option of random access in addition to linear traversal of the database.
|
||||
|
||||
\membersection{wxExprDatabase::BeginFind}\label{wxexprdatabasebeginfind}
|
||||
|
||||
\func{void}{BeginFind}{\void}
|
||||
|
||||
Reset the current position to the start of the database. Subsequent
|
||||
\rtfsp\helpref{wxExprDatabase::FindClause}{wxexprdatabasefindclause} calls will move the pointer.
|
||||
|
||||
\membersection{wxExprDatabase::ClearDatabase}\label{wxexprdatabasecleardatabase}
|
||||
|
||||
\func{void}{ClearDatabase}{\void}
|
||||
|
||||
Clears the contents of the database.
|
||||
|
||||
\membersection{wxExprDatabase::FindClause}\label{wxexprdatabasefindclause}
|
||||
|
||||
Various ways of retrieving clauses from the database. A return
|
||||
value of NULL indicates no (more) clauses matching the given criteria.
|
||||
Calling the functions repeatedly retrieves more matching clauses, if any.
|
||||
|
||||
\func{wxExpr* }{FindClause}{\param{long}{ id}}
|
||||
|
||||
Find a clause based on the special ``id'' attribute.
|
||||
|
||||
\func{wxExpr* }{FindClause}{\param{const wxString\&}{ attribute}, \param{const wxString\&}{ value}}
|
||||
|
||||
Find a clause which has the given attribute set to the given string or word value.
|
||||
|
||||
\func{wxExpr*}{FindClause}{\param{const wxString\&}{ attribute}, \param{long}{ value}}
|
||||
|
||||
Find a clause which has the given attribute set to the given integer value.
|
||||
|
||||
\func{wxExpr*}{FindClause}{\param{const wxString\&}{ attribute}, \param{float}{ value}}
|
||||
|
||||
Find a clause which has the given attribute set to the given floating point value.
|
||||
|
||||
\membersection{wxExprDatabase::FindClauseByFunctor}\label{wxexprdatabasefindclausebyfunctor}
|
||||
|
||||
\func{wxExpr*}{FindClauseByFunctor}{\param{const wxString\&}{ functor}}
|
||||
|
||||
Find the next clause with the specified functor.
|
||||
|
||||
\membersection{wxExprDatabase::GetErrorCount}\label{wxexprdatabasegeterrorcount}
|
||||
|

\constfunc{wxExpr*}{HashFind}{\param{const wxString\&}{ functor}, \param{long}{ value}}
|
||||
|
||||
Finds the clause with the given functor and with the attribute specified
|
||||
in the database constructor having the given integer value.
|
||||
|
||||
For example,
|
||||
|
||||
\begin{verbatim}
|
||||
// Hash on a combination of functor and integer "id" attribute when reading in
|
||||
wxExprDatabase db(wxExprInteger, "id");
|
||||
|
||||
// Read it in
|
||||
db.ReadProlog("data");
|
||||
|
||||
// Retrieve a clause with specified functor and id
|
||||
wxExpr *clause = db.HashFind("node", 24);
|
||||
\end{verbatim}
|
||||
|
||||
This would retrieve a clause which is written: {\tt node(id = 24, ..., )}.
|
||||
|
||||
\func{wxExpr*}{HashFind}{\param{const wxString\&}{ functor}, \param{const wxString\&}{ value}}
|
||||
|
||||
Finds the clause with the given functor and with the attribute specified
|
||||
in the database constructor having the given string value.

|
||||
|

\func{bool}{ReadFromString}{\param{const wxString\&}{ buffer}}
|
||||
|

wxFindReplaceDialog is a standard modeless dialog which is used to allow the
|
||||
user to search for some text (and possibly replace it with something else).
|
||||
The actual searching is supposed to be done in the owner window which is the
|
||||
parent of this dialog. Note that it means that unlike for the other standard
|
||||
dialogs this one {\bf must} have a parent window. Also note that there is no
|
||||
way to use this dialog in a modal way; it is always, by design and
|
||||
implementation, modeless.
|
||||
|
||||
Please see the dialogs sample for an example of using it.

\section{\class{wxFFile}}\label{wxffile}

wxFFile implements buffered file I/O. This is a very small class designed to
|
||||
minimize the overhead of using it - in fact, there is hardly any overhead at
|
||||
all, but using it brings you automatic error checking and hides differences
|
||||
between platforms and compilers. It wraps inside it a {\tt FILE *} handle used
|

by standard C IO library (also known as {\tt stdio}).

two such groups of classes: this one is based on \helpref{wxFFile}{wxffile}
|
||||
whereas \helpref{wxFileInputStream}{wxfileinputstream} is based in
|
||||
the \helpref{wxFile}{wxfile} class.
|
||||
|
||||
Note that \helpref{wxFile}{wxfile} and \helpref{wxFFile}{wxffile} differ
|
||||
in one aspect, namely when to report that the end of the file has been
|
||||
reached. This is documented in \helpref{wxFile::Eof}{wxfileeof} and
|
||||
\helpref{wxFFile::Eof}{wxffileeof} and the behaviour of the stream
|
||||
classes reflects this difference, i.e. wxFileInputStream will report
|
||||
wxSTREAM\_EOF after having read the last byte whereas wxFFileInputStream
|
||||
will report wxSTREAM\_EOF after trying to read {\it past} the last byte.

\section{\class{wxFileDataObject}}\label{wxfiledataobject}

wxFileDataObject is a specialization of \helpref{wxDataObject}{wxdataobject}

for file names. The program works with it just as if it were a list of absolute file
|

names, but internally it uses the same format as

\section{\class{wxFile}}\label{wxfile}
|
||||
|
||||
A wxFile performs raw file I/O. This is a very small class designed to
|
||||
minimize the overhead of using it - in fact, there is hardly any overhead at
|
||||
all, but using it brings you automatic error checking and hides differences
|
||||
between platforms and compilers. wxFile also automatically closes the file in
|
||||
its destructor making it unnecessary to worry about forgetting to do it.
|
||||
wxFile is a wrapper around {\tt file descriptor.} - see also
|
||||
\helpref{wxFFile}{wxffile} for a wrapper around {\tt FILE} structure.

||||

|
||||
<wx/file.h>
|
||||
|
||||
\wxheading{Constants}
|
||||
|
||||
wx/file.h defines the following constants:
|
||||
|
||||
\begin{verbatim}
|
||||
#define wxS_IRUSR 00400
|
||||
#define wxS_IWUSR 00200
|
||||
#define wxS_IXUSR 00100
|
||||
|
||||
#define wxS_IRGRP 00040
|
||||
#define wxS_IWGRP 00020
|
||||
#define wxS_IXGRP 00010
|
||||
|
||||
#define wxS_IROTH 00004
|
||||
#define wxS_IWOTH 00002
|
||||
#define wxS_IXOTH 00001
|
||||
|
||||
// default mode for the new files: corresponds to umask 022
|
||||
#define wxS_DEFAULT (wxS_IRUSR | wxS_IWUSR | wxS_IRGRP | wxS_IWGRP | wxS_IROTH | wxS_IWOTH)
|
||||
\end{verbatim}
|
||||
|
||||
These constants define the file access rights and are used with
|
||||
\helpref{wxFile::Create}{wxfilecreate} and \helpref{wxFile::Open}{wxfileopen}.
|
||||
|
||||
The {\it OpenMode} enumeration defines the different modes for opening a file,
|
||||
it is defined inside wxFile class so its members should be specified with {\it wxFile::} scope
|
||||
resolution prefix. It is also used with \helpref{wxFile::Access}{wxfileaccess} function.

||||
|
||||

|
||||
\begin{twocollist}\itemsep=0pt%

|
||||
\twocolitem{{\bf wxFile::write}}{Open file for writing deleting the contents of the file if it already exists
|
||||
or test if it can be opened for writing with Access()}
|
||||
\twocolitem{{\bf wxFile::read\_write}}{Open file for reading and writing; can not be used with Access()}
|
||||
\twocolitem{{\bf wxFile::write\_append}}{Open file for appending: the file is opened for writing, but the old
|
||||
contents of the file is not erased and the file pointer is initially placed at the end of the file;
|
||||
can not be used with Access(). This is the same as {\bf wxFile::write} if the
|
||||
file doesn't exist.}
|
||||
\twocolitem{{\bf wxFile::write\_excl}}{Open the file securely for writing (Uses O\_EXCL | O\_CREAT).
|
||||
Will fail if the file already exists, else create and open it atomically. Useful for opening temporary files without being vulnerable to race exploits.}
|
||||
\end{twocollist}
|
||||
|
||||
Other constants defined elsewhere but used by wxFile functions are wxInvalidOffset which represents an
|
||||
invalid value of type {\it off\_t} and is returned by functions returning {\it off\_t} on error and the seek
|
||||
mode constants used with \helpref{Seek()}{wxfileseek}:

Default constructor.
|
||||
|
||||
\func{}{wxFile}{\param{const char*}{ filename}, \param{wxFile::OpenMode}{ mode = wxFile::read}}
|
||||
|
||||
Opens a file with the given mode. As there is no way to return whether the
|
||||
operation was successful or not from the constructor you should test the
|
||||
return value of \helpref{IsOpened}{wxfileisopened} to check that it didn't
|
||||
fail.
|
||||
|
||||
\func{}{wxFile}{\param{int}{ fd}}
|
||||
|
||||
Associates the file with the given file descriptor, which has already been opened.
|
||||
|
||||
\wxheading{Parameters}
|
||||
|
||||
\docparam{filename}{The filename.}
|
||||
|

\docparam{fd}{An existing file descriptor (see \helpref{Attach()}{wxfileattach} for the list of predefined descriptors)}
|
||||
|
||||
\membersection{wxFile::\destruct{wxFile}}
|
||||
|
||||
\func{}{\destruct{wxFile}}{\void}
|
||||
|
||||
Destructor will close the file.
|
||||
|
||||
{\bf NB:} it is not virtual so you should not use wxFile polymorphically.
|
||||
|
||||
\membersection{wxFile::Access}\label{wxfileaccess}
|
||||
|
||||
\func{static bool}{Access}{\param{const char *}{ name}, \param{OpenMode}{ mode}}
|
||||
|
||||
This function verifies if we may access the given file in specified mode. Only
|
||||
values of wxFile::read or wxFile::write really make sense here.
|
||||
|
||||
\membersection{wxFile::Attach}\label{wxfileattach}
|
||||
|
||||
\func{void}{Attach}{\param{int}{ fd}}
|
||||
|
||||
Attaches an existing file descriptor to the wxFile object. Example of predefined
|
||||
file descriptors are 0, 1 and 2 which correspond to stdin, stdout and stderr (and
|
||||
have symbolic names of {\bf wxFile::fd\_stdin}, {\bf wxFile::fd\_stdout} and {\bf wxFile::fd\_stderr}).
|
||||
|
||||
The descriptor should be already opened and it will be closed by wxFile
|
||||
object.
|
||||
|
||||
\membersection{wxFile::Close}\label{wxfileclose}
|
||||
|
||||
\func{void}{Close}{\void}
|
||||
|
||||
Closes the file.
|
||||
|
||||
\membersection{wxFile::Create}\label{wxfilecreate}
|
||||
|
||||
\func{bool}{Create}{\param{const char*}{ filename}, \param{bool}{ overwrite = FALSE}, \param{int }{access = wxS\_DEFAULT}}
|
||||
|
||||
Creates a file for writing. If the file already exists, setting {\bf overwrite} to TRUE
|
||||
will ensure it is overwritten.
|
||||
|
||||
\membersection{wxFile::Detach}\label{wxfiledetach}
|
||||
|
||||
\func{void}{Detach}{\void}
|
||||
|
||||
Get back a file descriptor from wxFile object - the caller is responsible for closing the file if this
|
||||
descriptor is opened. \helpref{IsOpened()}{wxfileisopened} will return FALSE after call to Detach().
|
||||
|
||||
\membersection{wxFile::fd}\label{wxfilefd}
|
||||
|
||||
\constfunc{int}{fd}{\void}
|
||||
|
||||
Returns the file descriptor associated with the file.
|
||||
|
||||
\membersection{wxFile::Eof}\label{wxfileeof}
|
||||
|
||||
\constfunc{bool}{Eof}{\void}
|
||||
|
||||
Returns TRUE if the end of the file has been reached.
|
||||
|
||||
Note that the behaviour of the file pointer based class
|
||||
\helpref{wxFFile}{wxffile} is different as \helpref{wxFFile::Eof}{wxffileeof}
|
||||
will return TRUE here only if an attempt has been made to read
|
||||
{\it past} the last byte of the file, while wxFile::Eof() will return TRUE
|
||||
even before such attempt is made if the file pointer is at the last position
|
||||
in the file.
|
||||
|
||||
Note also that this function doesn't work on unseekable file descriptors
|
||||
(examples include pipes, terminals and sockets under Unix) and an attempt to
|
||||
use it will result in an error message in such case. So, to read the entire
|
||||
file into memory, you should write a loop which uses
|
||||
\helpref{Read}{wxfileread} repeatedly and tests its return condition instead
|
||||
of using Eof() as this will not work for special files under Unix.
|
||||
|
||||
\membersection{wxFile::Exists}\label{wxfileexists}
|
||||
|
||||
\func{static bool}{Exists}{\param{const char*}{ filename}}
|
||||
|
||||
Returns TRUE if the given name specifies an existing regular file (not a
|
||||
directory or a link)
|
||||
|
||||
\membersection{wxFile::Flush}\label{wxfileflush}
|
||||
|
||||
\func{bool}{Flush}{\void}
|
||||
|
||||
Flushes the file descriptor.
|
||||
|
||||
Note that wxFile::Flush is not implemented on some Windows compilers
|
||||
due to a missing fsync function, which reduces the usefulness of this function
|
||||
(it can still be called but it will do nothing on unsupported compilers).
|
||||
|
||||
\membersection{wxFile::IsOpened}\label{wxfileisopened}
|
||||
|
||||
\constfunc{bool}{IsOpened}{\void}
|
||||
|
||||
Returns TRUE if the file has been opened.
|
||||
|
||||
\membersection{wxFile::Length}\label{wxfilelength}
|
||||
|
||||
\constfunc{off\_t}{Length}{\void}
|
||||
|
||||
Returns the length of the file.
|
||||
|
||||
\membersection{wxFile::Open}\label{wxfileopen}
|
||||
|
||||
\func{bool}{Open}{\param{const char*}{ filename}, \param{wxFile::OpenMode}{ mode = wxFile::read}}
|

|
||||
Opens the file, returning TRUE if successful.

\wxheading{Parameters}
|

\wxheading{Remarks}
|
||||
|
||||
Pops up a file selector box. In Windows, this is the common file selector
|
||||
dialog. In X, this is a file selector box with somewhat less functionality.
|
||||
The path and filename are distinct elements of a full file pathname.
|
||||
If path is ``", the current directory will be used. If filename is ``",
|
||||
no default filename will be supplied. The wildcard determines what files
|
||||
are displayed in the file selector, and file extension supplies a type
|
||||
extension for the required filename. Flags may be a combination of wxOPEN,
|
||||
wxSAVE, wxOVERWRITE\_PROMPT, wxHIDE\_READONLY, wxFILE\_MUST\_EXIST, wxMULTIPLE or 0.
|
||||
|
||||
Both the X and Windows versions implement a wildcard filter. Typing a
|
||||
filename containing wildcards (*, ?) in the filename text item, and
|
||||
clicking on Ok, will result in only those files matching the pattern being
|
||||
displayed. The wildcard may be a specification for multiple
|
||||
types of file with a description for each, such as:
|
||||
|
||||
\begin{verbatim}
|
||||
"BMP files (*.bmp)|*.bmp|GIF files (*.gif)|*.gif"
|
||||
\end{verbatim}
|
||||
|
||||
It must be noted that wildcard support in the native Motif file
|
||||
dialog is quite limited: only one alternative is supported,
|
||||
and it is displayed without the descriptive test; ``BMP files (*.bmp)|*.bmp''
|
||||
is displayed as ``*.bmp'', and both
|
||||
``BMP files (*.bmp)|*.bmp|GIF files (*.gif)|*.gif'' and
|
||||
``Image files|*.bmp;*.gif'' are errors.
