wxWindows 2.0 for Windows Change Log
------------------------------------
Alpha 11, May ??th 1998
-----------------------
- Added thread.h, thread.cpp.
- Changed Enabled, Checked to IsEnabled, IsChecked in wxMenu,
wxMenuBar.
- Changed wxMenuItem::SetBackColor to SetBackgroundColour,
SetTextColor to SetTextColour, and added or made public several
wxMenuItem accessors.
- Added two overloads to wxRegion::Contains. Added
wxRegion::IsEmpty for a more consistent naming convention.
Alpha 10, May 7th 1998
----------------------
- Added desiredWidth, desiredHeight parameters to wxBitmapHandler
and wxIcon functions so that you can specify what size of
icon should be loaded. Probably will remain a Windows-specific thing.
- wxStatusBar95 now works for MDI frames.
- Toolbars in MDI frames now behave normally. They still
require application-supplied positioning code though.
- Changed installation instructions, makefiles and batch files
for compiling with Gnu-Win32/Mingw32/EGCS. Also timercmn.cpp
change to support Mingw32/EGCS. Bison now used by default.
Alpha 9, April 27th 1998
------------------------
- Cured bug in wxStatusBar95 that caused a crash if multiple
fields were used.
- Added Gnu-Win32 b19/Mingw32 support by changing resource
compilation and pragmas.
- Cured wxMenu bug introduced in alpha 8 - didn't respond to
commands because VZ changed the id setting in wxMenu::MSWCommand.
Alpha 8, April 17th 1998
------------------------
- Added IsNull to wxGDIObject to check if the ref data is present or not.
- Added PNG handler and sample - doesn't work for 16-bit PNGs for
some reason :-(
- Added wxJoystick class and event handling, and simple demo.
- Added simple wxWave class. Needs Stop() function.
- Added wxModule (module.h/module.cpp) to allow definition
of modules to be initialized and cleaned up on wxWindows
startup/exit.
- Start of Mingw32 compatibility (see minimal and dialogs samples
makefile.m95 files, and install.txt).
- Note: Windows printing has stopped working... will investigate.
VADIM'S CHANGES:
- Updated wxString: bug fixes, added wxArrayString, some
compatibility functions.
- Updated log.h/cpp, added wxApp::CreateLogTarget.
- file.h: new wxTempFile class.
- defs.h: added wxSB_SIZE_GRIP for wxStatusBar95
- statbr95: wxStatusBar95 control.
- registry.h/cpp: wxRegKey class for Win95 registry.
- listbox.cpp: corrected some bugs with owner-drawn listboxes.
- wxConfig and wxFileConfig classes.
Alpha 7, March 30th 1998
------------------------
- Added tab classes, tab sample.
- Now can return FALSE from OnInit and windows will be
cleaned up properly before exit.
- Improved border handling so panels don't get borders
automatically.
- Debugged MDI activation from Window menu.
- Changes to memory debug handling, including checking for
memory leaks on application exit - but see issues.txt for
unresolved issues.
- Added wxTaskBarIcon (taskbar.cpp/h, plus samples/taskbar)
to allow maintenance of an icon in the Windows 95 taskbar
tray area.
- Got MFC sample working (MFC and wxWindows in the same
application), partly by tweaking ntwxwin.mak settings.
- Got DLL compilation working again (VC++).
- Changed wxProp/Dialog Editor filenames.
Alpha 6, March 10th 1998
------------------------
- Found stack error bug - stopped unwanted OnIdle recursion.
- Removed bug in wxTreeCtrl::InsertItem I added in alpha 5.
- Changed exit behaviour in wxApp/wxFrame/wxDialog. Now will
check if the number of top-level windows is zero before
exiting. Also, wxApp::GetTopWindow will return either
m_topWindow or the first member of wxTopLevelWindows, so you
don't have to call wxApp::SetTopWindow.
- Added dynarray.h/dynarray.cpp (from Vadim).
- Added first cut at OLE drag and drop (from Vadim). dnd sample
added. Drop target only at this stage. See src/msw/ole/*.cpp,
wx/include/msw/ole/*.h. WIN32 only because of UUID usage.
Doesn't work with GnuWin32 - no appropriate headers e.g. for
IUnknown.
Doesn't work with BC++ either - crashes on program startup.
- Added Vadim's owner-draw modifications - will probably remain
Windows-only. This enhances wxMenu, wxListBox. See ownerdrw sample.
- Added wxLB_OWNERDRAW for owner-draw listboxes.
- Vadim's wxCheckListBox derives from wxListBox. See checklst sample.
Doesn't entirely work for WIN16.
- Vadim has added wxMenuItem as a separate file menuitem.cpp. It
can also be used as an argument to wxMenu::Append, not just for
internal implementation.
- Some #ifdefs done for MINGW32 compilation (just alter OPTIONS
in makeg95.env, together with mingw32.bat). However, resource
binding is not working yet so most apps with dialogs crash.
Alpha 5, 14th February 1998
---------------------------
- GENERIC AND MSW-SPECIFIC CODE NOW TREATED AS TWO SEPARATE
DISTRIBUTIONS. This change log will therefore now refer to
the Windows-specific code only. See docs/changes.txt for generic
changes.
- Removed Windows-specific reference counting system (GDI
resources were cleaned up in idle time) - minimal
advantages now we have a wxWin reference counting system.
- Added missing WXDLLEXPORT keywords so DLL compilation works
again.
- Removed most warnings for GnuWin32 compilation.
- Added wxRegion/wxRegionIterator, but haven't yet used it in
e.g. wxDC.
Alpha 4, 31st January 1998
--------------------------
- Changed wxDC functions to take longs instead of floats. GetSize now takes
integer pointers, plus a version that returns a wxSize.
- const keyword added to various wxDC functions.
- Under Windows, wxDC no longer has any knowledge of whether
an associated window is scrolled or not. Instead, the device
origin is set by wxScrolledWindow in wxScrolledWindow::PrepareDC.
- wxScrolledWindow applications can optionally override the virtual OnDraw
function instead of using the OnPaint event handler. The wxDC passed to
OnDraw will be translated by PrepareDC to reflect scrolling.
When drawing outside of OnDraw, must call PrepareDC explicitly.
- wxToolBarBase/wxToolBarSimple similarly changed to allow for
scrolling toolbars.
- Integrated wxPostScriptDC patches for 1.xx by Chris Breeze,
to help printing with multiple pages.
- IPC classes given base classes (wxConnectionBase etc.) which
define the API used by different implementations. DDE
implementation updated to use these base classes.
- wxHelpInstance now separated into wxHelpControllerBase (base
for all implementations), wxWinHelpController (uses standard
WinHelp), wxXLPHelPController (talks to wxHelp by DDE or
TCP/IP). There will be others eventually, such as
wxHTMLHelpController for Microsoft (and Netscape?) HTML Help.
- Added Vadim Zeitlin's wxString class plus
internationalization code (gettext simulation, wxLocale, etc.).
New files from Vadim:
include\wx\string.h
include\wx\debug.h
include\wx\file.h
include\wx\log.h
include\wx\intl.h
src\common\string.cpp
src\common\log.cpp
src\common\intl.cpp
src\common\file.cpp
No longer use GNU wxString files.
- Split off file-related functions into include\wx\filefn.h and
src\common\filefn.cpp.
- Borland C++ support (WIN32) for main library and
samples, using makefile.b32 files.
- Preparation done for allowing BC++ to compile wxWin as a DLL,
including changes to defs.h.
- wxIntPoint removed, wxPoint is now int, and wxRealPoint
introduced.
- Added wxShowEvent (generated when window is being shown or
hidden).
- Got minimal, docview, mdi samples working for 16-bit VC++ and
cured 16-bit problem with wxTextCtrl (removed global memory
trick).
- Updated GnuWin32 makefiles, checked minimal, mdi, docview samples.
Alpha 3, September 1997
-----------------------
- wxListCtrl, wxTreeCtrl, wxImageList classes done.
- Instigated new file hierarchy, split files and classes up more logically.
- PrologIO and some other utils now put into core library.
- Revamped print/preview classes, added wxPageSetupDialog.
- Started documentation.
Alpha 2, 30th April 1997
------------------------
- EVT_... macros now have at least one argument, for conformance
with MetroWerks compiler.
- Added ids to .wxr file format.
- Got Dialog Editor compiled and running again but need
to extend functionality to be in line with new controls.
Added dialoged\test app to allow dynamic loading of .wxr files
for testing purposes.
- Rewrote wxBitmap to allow installable file type
handlers.
- Rewrote wxBitmapButton, wxStaticBitmap to not use Fafa.
- Wrote most of wxTreeCtrl and sample (need wxImageList to implement it
fully).
- Added back wxRadioBox.
- Tidied up wx_main.cpp, wxApp class, putting PenWin code in
a separate file.
Alpha 1, 5th April 1997
-----------------------
At this point, the following has been achieved:
- A lot, but not all, of the code has been revamped for better
naming conventions, protection of data members, and use of
wxString instead of char *.
- Obsolete functionality deleted (e.g. default wxPanel layout,
old system event system) and code size reduced.
- Class hierarchy changed (see design doc) - base classes such
as wxbWindow now removed.
- No longer includes windows.h in wxWin headers, by using stand-in
Windows types where needed e.g. WXHWND.
- PrologIO revised.
- wxScrolledWindow, wxStatusBar and new MDI classes added.
MDI is now achived using separate classes, not window styles.
- wxSystemSettings added, and made use of to reflect standard
Windows settings.
- SetButtonFont/SetLabelFont replaced by SetFont; font and colour
settings mucho rationalised.
- All windows are now subclassed with the same window proc to make
event handling far more consistent. Old internal wxWnd and derived
classes removed.
- API for controls revised, in particular addition of
wxValidator parameters and removal of labels for some controls.
- 1 validator written: see examples/validate.
- Event table system introduced (see most samples and
wx_event.cpp/ProcessEvent, wx_event.h). wxEvtHandler
made more flexible, with Push/PopEventHandler allowing a chain
of event handlers.
- wxRadioBox removed - will be added back soon.
- Toolbar class hierarchy revised:
wxToolBarBase
wxToolBarSimple (= old wxToolBar)
wxToolBar95 (= old wxButtonBar under Win95
wxToolBarMSW (= old wxButtonBar under WIN16/WIN32)
- Constraint system debugged somewhat (sizers now work properly).
- wxFileDialog, wxDirDialog added; other common dialogs now
have class equivalents. Generic colour and font dialogs
rewritten to not need obsolete panel layout.
- .wxr resource system partially reinstated, though needs
an integer ID for controls. Hopefully the resource system
will be replaced by something better and more efficient
in the future.
- Device contexts no longer stored with window and accessed
with GetDC - use wxClientDC, wxPaintDC, wxWindowDC stack
variables instead.
- wxSlider uses trackbar class under Win95, and wxSL_LABELS flag
determines whether labels are shown. Other Win95-specific flags
introduced, e.g. for showing ticks.
- Styles introduced for dealing with 3D effects per window, for
any window: all Win95 3D effects supported, plus transparent windows.
- Major change to allow 3D effect support without CTL3D, under
Win95.
- Bitmap versions of button and checkbox separated out into new
classes, but unimplemented as yet because I intend to remove
the need for Fafa - it apparently causes GPFs in Win95 OSR 2.
- utils/wxprop classes working (except maybe wxPropertyFormView)
in preparation for use in Dialog Editor.
- GNU-WIN32 compilation verified (a month or so ago).

Installing wxWindows 2.0
------------------------
Unarchiving
-----------
If there is a setup program, run the setup program that comes with the Windows version.
Do not install into a path that contains spaces. The installation program should set the
WXWIN environment variable, which will be activated when your machine is rebooted.
If there is no setup program, it will come as a series of .zip
files:
wx200gen.zip Generic source code and samples (required)
wx200msw.zip Windows-specific source code and samples (required)
wx200doc.zip Documentation source code (not required)
wx200hlp.zip WinHelp documentation
wx200ps.zip PostScript documentation (will probably
disappear in favour of PDF)
wx200pdf.zip Acrobat PDF documentation
wx200htm.zip HTML documentation
Unarchive the required files plus any optional documentation
files into a suitable directory such as c:\wx. Alter your
WXWIN environment variable to point to this directory.
Compilation
-----------
At present, wxWindows compiles with VC++ 1.5, VC++ 4.0, VC++ 5.0,
BC++ 4.5/5.0, Gnu-Win32 b19, and Mingw32.
Visual C++ 4.0/5.0 compilation
------------------------------
1. Change directory to wx\src\msw. Type 'nmake -f makefile.nt' to
make the wxWindows core library.
2. Change directory to wx\samples and type 'nmake -f makefile.nt'
to make all the samples. You can also make them individually.
Visual C++ 1.5 compilation
--------------------------
1. Change directory to wx\src\msw. Type 'nmake -f makefile.dos' to
make the wxWindows core library.
2. Change directory to wx\samples and type 'nmake -f makefile.b32'
to make all the samples. You can also make them individually.
NOTE: only a few samples have up-to-date makefiles, e.g.
minimal, docview, mdi. The utils makefile does not yet work.
Borland C++ 4.5/5.0 compilation
-------------------------------
1. Change directory to wx\src\msw. Type 'make -f makefile.b32' to
make the wxWindows core library.
2. Change directory to wx\samples and type 'make -f makefile.b32'
to make all the samples. You can also make them individually.
NOTE: only a few samples have up-to-date makefiles, e.g.
minimal, docview, mdi. The utils makefile does not yet work.
Gnu-Win32 b19/Mingw32 compilation
---------------------------------
wxWindows 2.0 supports Gnu-Win32 b19, Mingw32, and Mingw32/EGCS.
Thanks are due to Keith Garry Boyce (garp@opustel.com) and Cygnus for making
it all possible.
From wxWindows 2.0 beta 9, both Gnu-Win32 b19 and Mingw32 (the minimal
distribution of Gnu-Win32) can be used with the same makefiles.
Here are the steps required:
- Retrieve and install the latest beta of Gnu-Win32, or Mingw32, as per the
instructions with either of these packages.
- If using Mingw32 (including the EGCS variant), you need some
extra files to use the wxWindows makefiles. You can find these
files in ports/mingw32 on the ftp site or CD-ROM, as extra.zip.
These should be extracted to the Mingw32 directory.
- Modify the file wx/src/cygnus.bat (or mingw32.bat or mingegcs.bat)
to set up appropriate variables, if necessary mounting drives.
Run it before compiling.
- For Gnu-Win32, make sure there's a \tmp directory on your
Windows drive or bison will crash.
- Edit wx/src/makeg95.env and search for MINGW32. Take note of
the comments for adjusting settings to suit Gnu-Win32 or
Mingw32. Basically, this is just a case of adding the __MINGW32__ symbol
to OPTIONS for Mingw32, or removing it for Cygnus Gnu-Win32.
For Mingw32/EGCS, add both __MINGW32__ and __EGCS__.
- Use the makefile.g95 files for compiling wxWindows and samples,
e.g.:
> cd c:\wx\src\msw
> make -f makefile.g95
> cd c:\wx\samples\minimal
> make -f makefile.g95
- Use the 'strip' command to reduce executable size.
- With Cygnus Gnu-Win32, you can invoke gdb --nw myfile.exe to
debug an executable.
- If using GnuWin32 b18, you will need to copy windres.exe
from e.g. the Mingw32 distribution, to a directory in your path.
All targets have 'clean' targets to allow removal of object files
and other intermediate compiler files.
Gotchas:
- libwx.a is 28 MB or more.
- install.exe doesn't have built-in decompression because lzexpand.lib
isn't available with Gnu-Win32. However, you can use it with external
decompression utilities.

Current issues and bugs
-----------------------
Debugging code
--------------
wxDebugContext and global memory operators doesn't work correctly,
for different (unresolved) reasons on different compilers.
1) In VC++ 5.0, if you use wxDebugAlloc for new and wxDebugFree
for delete, you get a crash to do with deallocating the debug
buffer in wxDebugContext. So although the global operators are
defined, they are #ifdefed to just call malloc and free to avoid
the problem. This means that non-object memory checking doesn't work.
The problem does seem to be something to do with a pointer
mysteriously changing its address, very similar to 2).
2) In BC++ 4.5, there isn't a crash, but instead the ofstream
pointer passed to SetStream from SetFile (which is called in
memcheck.cpp) gets mysteriously changed as it's passed to SetStream.
This means that when counting the number of outstanding memory
blocks, we can't compare the allocated block with m_debugStream
to say 'ignore this block because we can't free it before the
very end of the application'. Therefore it always looks like
there's a memory leak of one object, in memory.cpp, unless you
don't call wxDebugContext::SetFile.
The fact that pointers appear to change in both cases must
indicate a common problem and solution. If we could use the
standard global memory operators for ofstream and
wxDebugStreamBuf it might help, but I don't know how to do that -
I've redefined 'new' throughout as WXDEBUG_NEW (which is itself
defined as the 3-argument operator).
Config/registry classes
-----------------------
Problems with Karsten's/Vadim's existing AppConfig classes:
- use char* a lot instead of wxString
- rather hard to understand
- will need fairly substantial rewrite
- no native .ini functions (?) for guaranteed Windows
compatibility
- new wxWin docs required
Good things:
- exists!
- FileConfig independent of OS
- specifying a base class that will meet nearly all needs for
derived classes
- enumerator
Other features we should probably have:
- ability to specify vendor name/app name in constructor
- under Windows, ability to read/write all areas of registry
as an option
Options:
- rewrite AppConfig
- start from own CRegistry class
- take elements from both
- do the Windows stuff, let someone else write/adapt the
non-Windows classes

Todo on wxWin 2.0, Windows platform
-----------------------------------
HIGH PRIORITY
-------------
Integrate Robert's wxGrid enhancements.
Find/add wxThread sample - Arthur T-D?
wxControl dimensions should be optionally based on dialog font
size for portability (dialog units as per Windows).
Implement wxDC floating point transformations.
Remove transformation from device to logical coordinates from
events e.g. mouse events.
Add wxDC::DeviceToLogical -> wxPoint etc (convenience accessors).
Revamp Dialog Editor for new controls and properties (e.g.
window id).
Registry classes (check out wxConfig class - see issues.txt).
Update manual.
wxApp changes DONE
wxMenu changes DONE
wxModule DONE
wxRegion DONE
wxFile DONE
wxTempFile
wxMask DONE
wxDC:Blit DONE
wxTaskBarIcon DONE
wxMsgCatalog etc.
wxLog
wxConfig, wxRegKey
wxTabCtrl
wxWave
wxJoystick
wxStatusBar95 and wxFrame status bar functions
wxListBox changes (for ownerdraw functionality)
wxThread
wxString
wxTString
Drag and drop (change API if required, e.g. const).
wxCheckListBox
wxBaseArray, other arrays
(wxOwnerDrawn)
Various events
Document the include file for each class
Write tutorial.
Other static classes.
Makefiles for other compilers. Generic makefiles?
Rewrite makefiles to maintain simultaneous debug/release
objects.
More wxSystemSettings (see comment in settings.cpp).
wxSocket integration.
wxListCtrl, wxTreeCtrl, wxImageList integration with Robert
Roebling's classes.
Convert OGL, other utilities and samples.
Check TODO entries.
Change #include "wx/xxx.h" to #include <wx/xxx.h>
Tidy code further, e.g. formatting from DevStudio, plus
standard header.
Shell function to invoke a document with open, print, whatever...
wxTextCtrl (and wxMultiText/wxTextWindow in wxWin 1.xx) - differences between Edit
and RichEdit controls.
Make use of Vadim's gettext implementation throughout wxWin code.
Document it.
Change wxUpdateIterator to use wxRegion; or scrap
wxUpdateIterator? See wxGTK.
Check WXWIN_COMPATIBILITY mode, remove any unnecessary #ifdefs.
Retain callback functions; have semi-compatible callback function prototypes
for all controls, at least in WXWIN_COMPATIBLE mode, but
retain (Set)Callback for all compilations. This is following a
panicky response to losing callbacks.
Merge dib.cpp, dibutils.cpp.
Simplify the toolbar samples.
Add a wxTabCtrl sample.
LOW PRIORITY
------------
Debug PNG support in wxBitmap (no 4-bit support), and possibly add a convertor from PNG
to HICON. We could perhaps also support inclusion of PNGs into
a .res file as a custom resource.
Fonts: ability to enumerate them.
Angled text.
Eliminate Set/GetDefaultBackgroundColour? Just take background
colour for child control instead.
Think about reimplementing wxBitmapButton, wxStaticBitmap using
BS_BITMAP, SS_BITMAP - but this may not allow wxBitmap
argument, so instead just allow controls loaded from native
resource to deal with this style and call default processing.
Completion of drag and drop support (Vadim).
Better clipboard support.
Toolbars: use event tables not virtual functions.
wxWizard class?
Doc/view - have some standard views/docs e.g. wxTextView.
wxClassWizard for generating files, chunks of code.
Miscellaneous file/system function wrappers.
wxImage or replacement; further wxBitmap/wxIcon etc. functions
(load animated icos).
Integrate existing multimedia classes.
Rich text class?
Optimize size further.
wxThread integration.
Look at WinCE stuff incl. database classes.
Improve conversion guide, compatibility classes, tools?
Bug database.
ActiveX support?
OpenGL integration.
Menu bitmaps - document Vadim's enhancements.
Enhance Tex2RTF to generate Microsoft HTML help, perhaps Netscape
HTML help also.
wxCreateDynamicObject is apparently slow: ~ 2000 calls to strcmp. Need to
use some kind of hash table scheme.
Write wxDisplay class for querying settings and passing
to wxFrame to mirror the X situation (multiple displays).
Write translator between old and new .wxr formats (including
substituting static text for obsolete labels).
Improve and expand wxSizer classes.
Write more validators.
Classes for file/OS utility functions.
Add support for more static controls e.g. wxStaticLine.
GDI objects could be optimised further in constructors by
searching for a matching, pre-existing object, and assigning from
that, thus sharing the internal handle. A problem with this
arises if you wish to change the data. But this can be handled by
un-refing and creating a new handle. So we could reuse many
Windows GDI objects without troubling the programmer. We might
wish to switch this off in certain circumstances, e.g.
wxEnableGDIReuse(FALSE);
wxBrush brush(...);
wxEnableGDIReuse(TRUE);
or even
wxGDIReuse reuse(FALSE);
wxBrush brush(...);
which lasts until its scope ends. This might be needed e.g. if we
needed to ensure that the operation was maximally efficient
(creating a new object rather than searching may or may not be
more efficient).
Perhaps rewrite wxFile to use FILE* descriptors, so Eof and Flush
can work.
