\chapter{OGLEdit: a sample OGL application}\label{ogledit}%
\setheader{{\it CHAPTER \thechapter}}{}{}{}{}{{\it CHAPTER \thechapter}}%
\setfooter{\thepage}{}{}{}{}{\thepage}
OGLEdit is a sample OGL application that allows the user to draw, edit,
save and load a few shapes. It should clarify aspects of OGL usage, and
can act as a template for similar applications. OGLEdit can be found in\rtfsp
{\tt samples/ogledit} in the OGL distribution.
$$\image{10cm;0cm}{ogledit.eps}$$\par
The wxWindows document/view model has been used in OGL, to reduce the amount of
housekeeping logic required to get it up and running. OGLEdit also provides
a demonstration of the Undo/Redo capability supported by the document/view classes,
and how a typical application might implement this feature.
\section{OGLEdit files}
OGLEdit comprises the following source files.
\begin{itemize}\itemsep=0pt
\item doc.h, doc.cpp: MyDiagram, DiagramDocument, DiagramCommand, MyEvtHandler
classes related to diagram functionality and documents.
\item view.h, view.cpp: MyCanvas, DiagramView classes related to visualisation of
the diagram.
\item ogledit.h, ogledit.cpp: MyFrame, MyApp classes related to the overall application.
\item palette.h, palette.cpp: EditorToolPalette implementing the shape palette.
\end{itemize}
\section{How OGLEdit works}
OGLEdit defines a DiagramDocument class, each of instance of which holds a MyDiagram
member which itself contains the shapes.
In order to implement specific mouse behaviour for shapes, a class MyEvtHandler is
defined which is `plugged into' each shape when it is created, instead of overriding each shape class
individually. This event handler class also holds a label string.
The DiagramCommand class is the key to implementing Undo/Redo. Each instance of DiagramCommand
stores enough information about an operation (create, delete, change colour etc.) to allow
it to carry out (or undo) its command. In DiagramView::OnMenuCommand, when the user initiates the
command, a new DiagramCommand instance is created which is then sent to the document's
command processor (see wxWindows manual for more information about doc/view and command
processing).
Apart from menu commands, another way commands are initiated is by the user left-clicking on
the canvas or right-dragging on a node. MyCanvas::OnLeftClick in view.cpp shows how
the appropriate wxClassInfo is passed to a DiagramCommand, to allow DiagramCommand::Do
to create a new shape given the wxClassInfo.
The MyEvtHandler right-drag methods in doc.cpp implement drawing a line between
two shapes, detecting where the right mouse button was released and looking for a second
shape. Again, a new DiagramCommand instance is created and passed to the command
processor to carry out the command.
DiagramCommand::Do and DiagramCommand::Undo embody much of the
interesting interaction with the OGL library. A complication of note
when implementing undo is the problem of deleting a node shape which has
one or more arcs attached to it. If you delete the node, the arc(s)
should be deleted too. But multiple arc deletion represents more information
that can be incorporated in the existing DiagramCommand scheme. OGLEdit
copes with this by treating each arc deletion as a separate command, and
sending Cut commands recursively, providing an undo path. Undoing such a
Cut will only undo one command at a time - not a one to one
correspondence with the original command - but it's a reasonable
compromise and preserves Do/Undo whilst keeping our DiagramCommand class
simple.
\section{Possible enhancements}
OGLEdit is very simplistic and does not employ the more advanced features
of OGL, such as:
\begin{itemize}\itemsep=0pt
\item attachment points (arcs are drawn to particular points on a shape)
\item metafile and bitmaps shapes
\item divided rectangles
\item composite shapes, and constraints
\item creating labels in shape regions
\item arc labels (OGL has support for three movable labels per arc)
\item spline and multiple-segment line arcs
\item adding annotations to node and arc shapes
\item line-straightening (supported by OGL) and alignment (not supported directly by OGL)
\end{itemize}
These could be added to OGLEdit, at the risk of making it a less
useful example for beginners.

%% C callback
%%
\wxheading{C callback for wxSound event}
When a sound event is generated, it may either call the internal sound event
processor (which can be inherited) or call a C function. Its definition is:
\begin{verbatim}
typedef void (*wxSoundCallback)(wxSoundStream *stream, int evt,
void *cdata);
\end{verbatim}
The {\bf stream} parameter represents the current wxSoundStream.
The {\bf evt} parameter represents the sound event which is the cause of the calling. (See \helpref{wxSound events}{wxsoundstream}).
The {\bf cdata} parameter represents the user callback data which were specified
when the user called \helpref{wxSoundStream::Register}{wxsoundstreamregister}.
{\it Note:} There are two other ways to catch sound events: you can inherit the
sound stream and redefine \helpref{wxSoundStream::OnSoundEvent}{wxsoundstreamonsoundevent}, or you can reroute the events to another sound stream using \helpref{wxSoundStream::SetEventHandler}{wxsoundstreamseteventhandler}.
%%
%% wxSoundStream streaming mode
%%
\wxheading{wxSound streaming mode}
The wxSoundStream object can work in three different modes. These modes are specified
at the call to \helpref{wxSoundStream::StartProduction}{wxsoundstreamstartproduction}
and cannot be changed until you call
\helpref{wxSoundStream::StopProduction}{wxsoundstreamstopproduction}.
The {\bf wxSOUND\_INPUT} mode is the recording mode. It generates {\bf wxSOUND\_INPUT}
events and you cannot use wxSoundStream::Write().
The {\bf wxSOUND\_OUTPUT} mode is the playing mode. It generates {\bf wxSOUND\_OUTPUT}
events and you cannot use wxSoundStream::Read().
The {\bf wxSOUND\_DUPLEX} mode activates the full duplex mode. The full duplex requires
you to make synchronous call to \helpref{wxSoundStream::Read}{wxsoundstreamread} and
\helpref{wxSoundStream::Write}{wxsoundstreamwrite}. This means that you must be
careful with realtime problems. Each time you call Read you must call Write.
%%
%% wxSoundStream events
%%
\wxheading{wxSoundStream events}
The sound events are generated when the sound driver (or the sound stream) completes
a previous sound buffer. There are two possible sound events and two meanings.
The {\bf wxSOUND\_INPUT} event is generated when the sound stream has a new input
buffer ready to be read. You know that you can read a buffer of the size
\helpref{GetBestSize()}{wxsoundstreamgetbestsize} without blocking.
The {\bf wxSOUND\_OUTPUT} event is generated when the sound stream has completed a
previous buffer. This buffer has been sent to the sound driver and it is ready to
process a new buffer. Consequently, \helpref{Write}{wxsoundstreamwrite} will not
block too.
\latexignore{\rtfignore{\wxheading{Members}}}
%% Ctor && Dtor
\membersection{wxSoundStream::wxSoundStream}\label{wxsoundstreamwxsoundstream}
\func{}{wxSoundStream}{\void}
Default constructor.
\membersection{wxSoundStream::\destruct{wxSoundStream}}\label{wxsoundstreamdtor}
\func{}{\destruct{wxSoundStream}}{\void}
Destructor. The destructor stops automatically all started production and destroys
any temporary buffer.
%%
%% Read
%%
\membersection{wxSoundStream::Read}\label{wxsoundstreamread}
\func{wxSoundStream\&}{Read}{\param{void* }{buffer}, \param{wxUint32 }{len}}
Reads {\it len} bytes from the sound stream. This call may block the user so
use it carefully when you need to intensively refresh the GUI. You may be
interested by sound events: see \helpref{wxSoundStream::OnSoundEvent}{wxsoundstreamonsoundevent}.
It is better to use the size returned by \helpref{wxSoundStream::GetBestSize}{wxsoundstreamgetbestsize}: this may improve performance or accuracy of the
sound event system.
\wxheading{Parameters}
\docparam{len}{{\it len} is expressed in bytes. If you need to do conversions between bytes
and seconds use wxSoundFormat.
See \helpref{wxSoundFormatBase}{wxsoundformatbase}, \helpref{wxSoundStream::GetSoundFormat}{wxsoundstreamgetsoundformat}.}
\docparam{data}{Data in \it{buffer} are coded using the sound format attached to this sound
stream. The format is specified with
\helpref{SetSoundFormat}{wxsoundstreamsetsoundformat}.}
%%
%% Write
%%
\membersection{wxSoundStream::Write}\label{wxsoundstreamwrite}
\func{wxSoundStream\&}{Write}{\param{const void* }{buffer}, \param{wxUint32 }{len}}
Writes \it{len} bytes to the sound stream. This call may block the user so
use it carefully. You may be interested by sound events: see
\helpref{wxSoundStream::OnSoundEvent}{wxsoundstreamonsoundevent}.
It is better to use the size returned by \helpref{wxSoundStream::GetBestSize}{wxsoundstreamgetbestsize}: this may improve performance or accuracy of the
sound event system.
\wxheading{Parameters}
\docparam{len}{This is expressed in bytes. If you need to do conversions between bytes
and seconds use wxSoundFormat.
See \helpref{wxSoundFormatBase}{wxsoundformatbase}, \helpref{wxSoundStream::GetSoundFormat}{wxsoundstreamgetsoundformat}.}
\docparam{buffer}{Data in \it{buffer} are coded using the sound format attached to this sound
stream. The format is specified with
\helpref{SetSoundFormat}{wxsoundstreamsetsoundformat}.}
%%
%% GetBestSize
%%
\membersection{wxSoundStream::GetBestSize}\label{wxsoundstreamgetbestsize}
\constfunc{wxUint32}{GetBestSize}{\void}
This function returns the best size for IO calls. The best size provides you
a good alignment for data to be written (or read) to (or from) the sound stream.
So, when, for example, a sound event is sent, you are sure the sound stream
will not block for this buffer size.
%%
%% wxSoundStream:SetSoundFormat
%%
\membersection{wxSoundStream::SetSoundFormat}\label{wxsoundstreamsetsoundformat}
\func{bool}{SetSoundFormat}{\param{const wxSoundFormatBase\& }{format}}
SetSoundFormat is one of the key function of the wxSoundStream object.
It specifies the sound format the user needs. SetSoundFormat tries to
apply the format to the current sound stream (it can be a sound file or a
sound driver). Then, either it manages to apply it and it returns {\bf TRUE},
or it could not and it returns {\bf FALSE}. In this case, you must check
the error with
\helpref{wxSoundStream::GetError}{wxsoundstreamgeterror}. See
\helpref{wxSoundStream errors section}{wxsoundstreamerrors} for more details.
\wxheading{Note}
The {\bf format} object can be destroyed after the call. The object does not need it.
\wxheading{Note}
If the error is {\bf wxSOUND\_NOTEXACT}, the stream tries to find the best
approaching format and setups it. You can check the format which it applied
with \helpref{wxSoundStream::GetSoundFormat}{wxsoundstreamgetsoundformat}.
%%
%% GetSoundFormat
%%
\membersection{wxSoundStream::GetSoundFormat}\label{wxsoundstreamgetsoundformat}
\constfunc{wxSoundFormatBase\&}{GetSoundFormat}{\void}
It returns a reference to the current sound format of the stream represented by a
wxSoundFormatBase object. This object {\it must not} be destroyed by anyone except
the stream itself.
%%
%% SetCallback
%%
\membersection{wxSoundStream::SetCallback}\label{wxsoundstreamregister}
\func{void}{Register}{\param{int }{evt}, \param{wxSoundCallback }{cbk}, \param{void* }{cdata}}
It installs a C callback for wxSoundStream events. The C callbacks are still
useful to avoid hard inheritance. You can install only one callback per event.
Each callback has its callback data.
%%
%% StartProduction
%%
\membersection{wxSoundStream::StartProduction}\label{wxsoundstreamstartproduction}
\func{bool}{StartProduction}{\param{int }{evt}}
StartProduction starts the sound streaming. {\it evt} may be one of
{\bf wxSOUND\_INPUT}, {\bf wxSOUND\_OUTPUT} or {\bf wxSOUND\_DUPLEX}.
You cannot specify several flags at the same time. Starting the production
may automaticaly in position of buffer underrun (only in the case you activated
recording). Actually this may happen the sound IO queue is too short.
It is also advised that you fill quickly enough the sound IO queue when the
driver requests it (through a wxSoundEvent).
\membersection{wxSoundStream::StopProduction}\label{wxsoundstreamstopproduction}
\func{bool}{StopProduction}{\void}
I stops the async notifier and the sound streaming straightly.
\membersection{wxSoundStream::SetEventHandler}\label{wxsoundstreamseteventhandler}
\func{void}{SetEventHandler}{\param{wxSoundStream* }{handler}}
Sets the event handler: if it is non-null, all events are routed to it.
\membersection{wxSoundStream::GetError}\label{wxsoundstreamgeterror}
\constfunc{wxSoundError}{GetError}{\void}
It returns the last error which occured.
\membersection{wxSoundStream::GetLastAccess}\label{wxsoundstreamgetlastaccess}
\constfunc{wxUint32}{GetLastAccess}{\void}
It returns the number of bytes which were effectively written to/read from the sound stream.
\membersection{wxSoundStream::QueueFilled}\label{wxsoundstreamqueuefilled}
\constfunc{bool}{QueueFilled}{\void}
It returns whether the sound IO queue is full. When it is full, the next IO call will block
until the IO queue has at least one empty entry.
\membersection{wxSoundStream::OnSoundEvent}\label{wxsoundstreamonsoundevent}
\func{void}{OnSoundEvent}{\param{int }{evt}}
It is called by the wxSoundStream when a new sound event occured.

\section{\class{wxSoundFileStream}}\label{wxsoundfilestream}
Base class for file coders/decoders. This class is not constructor (it is an abstract
class).
\wxheading{Derived from}
\helpref{wxSoundStream}{wxsoundstream}
\wxheading{Include file}
wx/sndfile.h
\wxheading{Data structures}
\latexignore{\rtfignore{\wxheading{Members}}}
\membersection{wxSoundFileStream::wxSoundFileStream}\label{wxsoundfilestreamwxsoundfilestream}
\func{}{wxSoundFileStream}{\param{wxInputStream\& }{stream}, \param{wxSoundStream\& }{io\_sound}}
It constructs a new file decoder object which will send
audio data to the specified sound stream.
The {\it stream} is the input stream to be decoded. The
{\it io_sound} is the destination sound stream.
Once it has been constructed, you cannot change any of
the specified streams nor the direction of the stream.
You will have access to the playback functions.
\func{}{wxSoundFileStream}{\param{wxOutputStream\& }{stream}, \param{wxSoundStream\& }{io\_sound}}
It constructs a new file coder object which will get
data to be recorded from the specified sound stream.
The {\it stream} is the output wxStream. The {\it io_sound}
is the source sound stream of the audio data. Once
it has been constructed, you cannot change any of
the specified streams nor the direction of the stream.
\membersection{wxSoundFileStream::\destruct{wxSoundFileStream}}\label{wxsoundfilestreamdtor}
\func{}{\destruct{wxSoundFileStream}}{\void}
It destroys the current sound file codec.
\membersection{wxSoundFileStream::Play}\label{wxsoundfilestreamplay}
\func{bool}{Play}{\void}
It starts playing the file. The playing begins, in background
in nearly all cases, after the return of the function. The
codec returns to a {\bf stopped} state when it reaches the
end of the file.
On success, it returns TRUE.
\membersection{wxSoundFileStream::Record}\label{wxsoundfilestreamrecord}
\func{bool}{Record}{\param{wxUint32 }{time}}
It starts recording data from the sound stream and writing them
to the output stream. You have to precise the recording length in
parameter. This length is expressed in seconds. If you want to
control the record length (using \helpref{Stop}{wxsoundfilestreamstop}),
you can set it to wxSOUND_INFINITE_TIME.
On success, it returns TRUE.
\membersection{wxSoundFileStream::Stop}\label{wxsoundfilestreamstop}
\func{bool}{Stop}{\void}
It stops either recording or playing. Whatever happens (even unexpected
errors), the stream is stopped when the function returns. When you are
in recording mode, the file headers are updated and flushed if possible
(ie: if the output stream is seekable).
On success, it returns TRUE.
\membersection{wxSoundFileStream::Pause}\label{wxsoundfilestreampause}
\func{bool}{Pause}{\void}
The file codec tries to pause the stream: it means that it stops audio
production but keep the file pointer at the place.
If the file codec is already paused, it returns FALSE.
On success, it returns TREE.
\membersection{wxSoundFileStream::Resume}\label{wxsoundfilestreamresume}
\func{bool}{Resume}{\void}
When the file codec has been paused using
\helpref{Pause}{wxsoundfilestreampause}, you could be interrested in
resuming it. This is the goal of this function.
\membersection{wxSoundFileStream::IsStopped}\label{wxsoundfilestreamisstopped}
\constfunc{bool}{IsStopped}{\void}
It returns TRUE when the stream is stopped, in another case it returns
FALSE.
\membersection{wxSoundFileStream::IsPaused}\label{wxsoundfilestreamispaused}
\constfunc{bool}{IsPaused}{\void}
It returns TRUE when the stream is paused, in another case it returns
FALSE.
\membersection{wxSoundFileStream::StartProduction}\label{wxsoundfilestreamstartproduction}
\func{bool}{StartProduction}{\param{int }{evt}}
It is really not advised you call this function. From the wxSoundFileStream
point of view it is an internal function. Internally, it is called after
the file stream has been prepared to be played or to receive audio data and
when it wants to start processing audio data.
\membersection{wxSoundFileStream::StopProduction}\label{wxsoundfilestreamstopproduction}
\func{bool}{StopProduction}{\void}
As for \helpref{StartProduction}{wxsoundfilestreamstopproduction}, it is not
advised for you to call this function. It is called by
\helpref{Stop}{wxsoundfilestreamstop} when it needs to stop the audio data
processing.
\membersection{wxSoundFileStream::GetLength}\label{wxsoundfilestreamgetlength}
\func{wxUint32}{GetLength}{\void}
It returns the audio data length of the file stream. This length is expressed
in bytes. If you need the length in seconds, you will need to use
\helpref{GetSoundFormat}{wxsoundstreamgetsoundformat} and
\helpref{GetTimeFromBytes}{wxsoundformatbasegettimefrombytes}.
\membersection{wxSoundFileStream::GetPosition}\label{wxsoundfilestreamgetposition}
\func{wxUint32}{GetPosition}{\void}
It returns the current position in the soundfile stream. The position
is expressed in bytes. If you need the length in seconds, you will need to use
\helpref{GetSoundFormat}{wxsoundstreamgetsoundformat} and
\helpref{GetTimeFromBytes}{wxsoundformatbasegettimefrombytes}.
\membersection{wxSoundFileStream::SetPosition}\label{wxsoundfilestreamsetposition}
\func{wxUint32}{SetPosition}{\param{wxUint32 }{new\_position}}
It sets the current in the soundfile stream. The position
{\it new\_position} must be expressed in bytes. You can get
a length/position in bytes from a time value using
\helpref{GetSoundFormat}{wxsoundstreamgetsoundformat} and
\helpref{GetTimeFromBytes}{wxsoundformatbasegettimefrombytes}.
On success, it returns TRUE.
\wxheading{Warning}
Some wxStream may not be capable to support this function as
it may not support the seekable functionnality. If this happens,
it returns FALSE and leave the stream at the same position.
\membersection{wxSoundFileStream::Read}\label{wxsoundfilestreamread}
\func{wxSoundStream\&}{Read}{\param{void* }{buffer}, \param{wxUint32 }{len}}
You can obtain the audio data encoded in the file using this function.
But it must be considered as an internal function. Used carelessly, it
may corrupt the current state of the stream.
Data are returned using in the original file coding (You must use a sound
format object to decode it).
\membersection{wxSoundFileStream::Write}\label{wxsoundfilestreamwrite}
\func{wxSoundStream\&}{Write}{\param{const void* }{buffer}, \param{wxUint32 }{len}}
You can put encoded audio data to the file using this function.
But it must be considered as an internal function. Used carelessly, it
may corrupt the current state of the stream.
Data must be coded with the specified file coding (You must use a sound
format object to do this).
\membersection{wxSoundFileStream::SetSoundFormat}\label{wxsoundfilestreamsetsoundformat}
\func{bool}{SetSoundFormat}{\param{const wxSoundFormatBase\& }{format}}
\membersection{wxSoundFileStream::GetCodecName}\label{wxsoundfilestreamgetcodecname}
\constfunc{wxString}{GetCodecName}{\void}
This function returns the Codec name. This is useful for those who
want to build a player (But also in some other case).
\membersection{wxSoundFileStream::CanRead}\label{wxsoundfilestreamcanread}
\func{bool}{CanRead}{\void}
You should use this function to test whether this file codec can read
the stream you passed to it.
\membersection{wxSoundFileStream::PrepareToPlay}\label{wxsoundfilestreampreparetoplay}
\func{bool}{PrepareToPlay}{\void}
\membersection{wxSoundFileStream::PrepareToRecord}\label{wxsoundfilestreampreparetorecord}
\func{bool}{PrepareToRecord}{\param{wxUint32 }{time}}
\membersection{wxSoundFileStream::FinishRecording}\label{wxsoundfilestreamfinishrecording}
\func{bool}{FinishRecording}{\void}
\membersection{wxSoundFileStream::RepositionStream}\label{wxsoundfilestreamrepositionstream}
\func{bool}{RepositionStream}{\param{wxUint32 }{position}}
\membersection{wxSoundFileStream::FinishPreparation}\label{wxsoundfilestreamfinishpreparation}
\func{void}{FinishPreparation}{\param{wxUint32 }{len}}
\membersection{wxSoundFileStream::GetData}\label{wxsoundfilestreamgetdata}
\func{wxUint32}{GetData}{\param{void* }{buffer}, \param{wxUint32 }{len}}

%
% Purpose
% -------
% Style file to enable the simultaneous preparation of printed LaTeX and on-line
% hypertext manuals.
% Use in conjunction with Tex2RTF (see Tex2RTF documentation).
%
% Note that if a non-ASCII character starts a newline and there should be a space
% between the last word on the previous line and the first word on this line,
% you need to use \rtfsp to generate a space in Windows Help. \rtfsp is ignored
% in all other formats.

% ============== C++/CLIPS Documentation Facilities ==============
%
% Each class definition should be typeset with e.g.
%
% \section{\class{Name}: Parent}
%
% followed by a description of the class.
% Each member should follow:
%
% \membersection{wxName::Member}
%
% with a description of what this member does.
% Then, one (or more if overloaded) member (function) in detail:
%
% \func{return type}{name}{args}
% or
% \member{type}{name}
%
% where args is a list of \param{type}{name}, ...

\chapter{Topic overviews}
\setheader{{\it CHAPTER \thechapter}}{}{}{}{}{{\it CHAPTER \thechapter}}%
\setfooter{\thepage}{}{}{}{}{\thepage}
The following sections describe particular topics.
\section{OGL overview}\label{ogloverview}
\helpref{wxShapeCanvas}{wxshapecanvas}, derived from {\bf wxCanvas}, is the drawing area
for a number of \helpref{wxShape}{wxshape} instances. Everything drawn on a
wxShapeCanvas is derived from wxShape, which provides virtual
member functions for redrawing, creating and destroying
resize/selection `handles', movement and erasing behaviour, mouse
click behaviour, calculating the bounding box of the shape, linking
nodes with arcs, and so on.
The way a client application copes with `damage' to the canvas is to
erase (white out) anything should no longer be displayed, redraw the shape,
and then redraw everything on the canvas to repair any damage. If quick edit
mode is on for the canvas, the complete should be omitted by OGL and the
application.
Selection handles (called control points in the code) are implemented as
wxRectangleShapes.
Events are passed to shapes by the canvas in a high-level form, for example {\bf OnLeftClick},
{\bf OnBeginDragLeft}, {\bf OnDragLeft}, {\bf OnEndDragLeft}. The canvas decides
what is a click and what is a drag, whether it is on a shape or the canvas itself,
and (by interrogating the shape) which attachment point the click is associated with.
In order to provide event-handling flexibility, each shapes has an `event handler' associated with it,
which by default is the shape itself (all shapes derive from wxShapeEvtHandler).
An application can modify the event-handling behaviour simply by plugging a new
event handler into the shape. This can avoid the need for multiple inheritance when
new properties and behaviour are required for a number of different shape classes: instead
of overriding each class, one new event handler class can be defined and used for all
existing shape classes.
A range of shapes have been predefined in the library, including rectangles, ellipses,
polygons. A client application can derive from these shapes and/or derive entirely
new shapes from wxShape.
Instances of a class called \helpref{wxDiagram}{wxdiagram} organise collections of
shapes, providing default file input and output behaviour.
\section{wxDividedShape overview}\label{dividedshapeoverview}
Classes: \helpref{wxDividedShape}{wxdividedshape}
A wxDividedShape is a rectangle with a number of vertical divisions. Each
division may have its text formatted with independent characteristics, and
the size of each division relative to the whole image may be specified.
Once a wxDividedShape has been created, the user may move the divisions with the
mouse. By pressing Ctrl while right-clicking, the region attributes can be edited.
Here are examples of creating wxDividedShape objects:
{\small
\begin{verbatim}
/*
* Divided rectangle with 3 regions
*
*/
wxDividedShape *dividedRect = new wxDividedShape(50, 60);
wxShapeRegion *region = new wxShapeRegion;
region->SetProportions(0.0, 0.25);
dividedRect->AddRegion(region);

\section{wxCompositeShape overview}\label{compositeshapeoverview}
Classes: \helpref{wxCompositeShape}{wxcompositeshape}, \helpref{wxOGLConstraint}{wxoglconstraint}
The wxCompositeShape allows fairly complex shapes to be created, and maintains
a set of constraints which specify the layout and proportions of child shapes.
Add child shapes to a wxCompositeShape using \helpref{AddChild}{wxcompositeshapeaddchild}, and
add constraints using \helpref{AddConstraint}{wxcompositeshapeaddconstraint}.
After children and shapes have been added, call \helpref{Recompute}{wxcompositeshaperecompute} which
will return TRUE is the constraints could be satisfied, FALSE otherwise. If
constraints have been correctly and consistently specified, this call will succeed.
If there is more than one child, constraints must be specified: OGL cannot calculate
the size and position of children otherwise. Don't assume that children will simply
move relative to the parent without the use of constraints.
To specify a constraint, you need three things:
\begin{enumerate}\itemsep=0pt
\item a constraint type, such as gyCONSTRAINT\_CENTRED\_VERTICALLY;
\item a reference shape, with respect to which other shapes are going to be positioned - the\rtfsp
{\it constraining} shape;
\item a list of one or more shapes to be constrained: the {\it constrained} shapes.
\end{enumerate}
The constraining shape can be either the parent of the constrained shapes, or a sibling. The
constrained shapes must all be siblings of each other.
For an exhaustive list and description of the available constraint types, see the \helpref{wxOGLConstraint constructor}{wxoglconstraintconstr}.
Note that most constraints operate in one dimension only (vertically or horizontally), so you will
usually need to specify constraints in pairs.
You can set the spacing between constraining and constrained shapes by
calling \helpref{wxOGLConstraint::SetSpacing}{wxoglconstraintsetspacing}.
Finally, a wxCompositeShape can have {\it divisions}, which are special child shapes of class
wxDivisionShape (not to be confused with wxDividedShape). The purpose of this is to allow
the composite to be divided into user-adjustable regions (divisions) into which other shapes
can be dropped dynamically, given suitable application code. Divisons allow the child
shapes to have an identity of their own - they can be manipulated independently of their container -
but to behave as if they are contained with the division, moving with the parent shape.
Divisions boundaries can themselves be moved using the mouse.
To create an initial division, call \helpref{wxCompositeShape::MakeContainer}{wxcompositeshapemakecontainer}.
Make further divisions by calling \helpref{wxDivisionShape::Divide}{wxdivisionshapedivide}.
