wxWindows 2 Change Log
----------------------
INCOMPATIBLE CHANGES SINCE 2.2.x
================================
wxBase:
- wxArray<T>::Remove(size_t) has been removed to fix compilation problems
under 64 bit architectures, please replace it with RemoveAt() in your
code.
- wxArray<T> macros have been changed to fix runtime problems under 64 bit
architectures and as a side effect of this WX_DEFINE_ARRAY() can only be
used now for the pointer types, WX_DEFINE_ARRAY_INT should be used for the
arrays containing non-pointers.
- wxObject::CopyObject() and Clone() methods were removed because they
simply don't make sense for all objects
- wxEvent now has a pure virtual Clone() method which must be implemented
by all derived classes, if you have user-defined event classes please
add "wxEvent *Clone() const { return new MyEvent(*this); }" line to them
- wxCondition now must be used with a mutex, please read the (updated) class
documentation for details and revise your code accordingly: this change was
unfortunately needed as the old class didn't behave correctly in all cases
- small change to wxStopWatch::Pause() semantics, please see the documentation
- unlikely but possible incompatibility: the definition of TRUE has changed
from "1" to "(bool)1" (and the same thing for FALSE), so the code which
could be erroneously compiled previously such as doing "return FALSE" from
a function returning a pointer would stop compiling now (but this change
is not supposed to have any effects on valid code)
All (GUI):
- the event type constants are not constants any more but are dynamically
allocated during run-time which means that they can't be used as case labels
in the switch()es, you must rewrite them to use if()s instead
You may also define WXWIN_COMPATIBILITY_EVENT_TYPES to get the old behaviour
but this is strongly discouraged, please consider changing your codei
instead!
- wxDialog does not derive from wxPanel any longer - if you were using it in
your code, please update it. The quick fix for the most cases is to replace
the occurences of wxPanel with wxWindow.
- wxYES_NO is now wxYES | wxNO and the manifest values of both wxYES and wxNO
have changed (to fix some unfortunate clashes), please check your code to
ensure that no tests for wxYES or wxNO are broken: for example, the following
will *NOT* work any longer:
if ( flags & wxYES_NO )
... do something ...
if ( flags & wxYES )
... do something else ...
- wxGLCanvas now derives directly from wxWindow, not wxScrolledWindow
- wxGridCellAttrProvider class API changed, you will need to update your code
if you derived any classes from it
- wxImage::ComputeHistogram()'s signature changed to
unsigned long ComputeHistogram(wxImageHistogram&) const
- wxEvtHandler cannot be copied/assigned any longer - this never worked but
now it results in compile-time error instead of run-time crashes
- WXK_NUMLOCK and WXK_SCROLL keys no longer result in EVT_CHAR() events,
they only generate EVT_KEY_DOWN/UP() ones
- the dialogs use wxApp::GetTopWindow() as the parent implicitly if the
parent specified is NULL, use wxDIALOG_NO_PARENT style to prevent this
from happening
wxMSW:
- build system changed: setup.h is not a static file in include/wx any more
but is created as part of the build process under lib/<toolkit>/wx/include
where <toolkit> is of the form (msw|univ)[dll][u][d]. You'll need to update
the include path in your make/project files appropriately. Furthermore,
xpm.lib is no longer used by wxMSW, it was superseded by the wxXPMDecoder
class. You'll need to remove all references to xpm.lib from your
make/project files.
- child frames appear in the taskbar by default now, use wxFRAME_NO_TASKBAR
style to avoid it, wxFRAME_FLOAT_ON_PARENT style is now obsolete and has no
effect
- all overloads of wxDC::SetClippingRegion() combine the given region with the
previously selected one instead of replacing it
- wxGetHomeDir() uses HOME environment variable and if it is set will not
return the programs directory any longer but its value (this function has
never been meant to return the programs directory anyhow)
- wxHTML apps don't need to include wx/html/msw/wxhtml.rc in resources file
anymore. The file was removed from wxMSW
Unix ports:
- You should use `wx-config --cxxflags` in your makefiles instead of
`wx-config --cflags` for compiling C++ files. CXXFLAGS contains CFLAGS
and the compiler flags for C++ files only, CFLAGS should still be used
to compile pure C files.

Beta 1, December 24th 1998
--------------------------
wxGTK:
- Various
wxMSW, wxMotif: not in sync with this release.
Alpha 18, December 29th 1998
----------------------------
wxMSW:
- Win16 support working again (VC++ 1.5)
- Win16 now uses generic wxNotebook, wxListCtrl,
wxTreeCtrl -- more or less working now, although
a little work on wxNotebook is still needed.
Under 16-bit Windows, get assertion when you click
on a tab.
- Wrote 16-bit BC++ makefiles: samples don't yet link.
- Added CodeWarrior support to distribution courtesy
of Stefan Csomor.
wxMotif:
- Cured scrolling problem: scrollbars now show/hide themselves
without (permanently) resizing the window.
- Removed some commented-out lines in wxScrolledWindow::AdjustScrollbars
that disabled scrollbar paging.
- Set background colour of drawing area in wxWindow, so e.g. wxListCtrl
colours correctly.
- Removed major bug whereby dialogs were unmanaged automatically
when any button was pressed.
- Fixed colours of wxWindow scrollbars, made list and text controls
have a white background.
- Fixed dialog colour setting.
- Added settable fonts and colours for wxMenu/wxMenuBar. Now
they have sensible colours by default.
- Fixed a bug in wxStaticBox.
- Cured wxTreeCtrl bug: now works pretty well!
- Debugged DrawEllipticArc (a ! in the wrong place).
- Added SetClippingRegion( const wxRegion& region ).

Alpha 17, November 22nd 1998
----------------------------
wxMSW:
- More documentation updates, especially for
wxLayoutWindow classes and debugging facilities.
- Changed wxDebugContext to use wxDebugLog instead
of wxTrace.
- Now supports VC++ 6.0, and hopefully BC++ 5.0.
However, DLL support may be broken for BC++ since
VC++ 6 required changing of WXDLLEXPORT keyword
position.
- Numerous miscellaneous changes.
wxMotif:
- Reimplemented MDI using wxNotebook instead of the MDI widgets, which
were too buggy (probably not design for dynamic addition/removal of
child frames).
- Some improvements to the wxNotebook implementation.
- wxToolBar now uses a bulletin board instead of a form, in an attempt
to make it possible to add ordinary wxControls to a toolbar.
- Cured problem with not being able to use global memory operators,
by defining two more global operators, so that the delete will match
the debugging implementation.
- Added wxUSE_DEBUG_NEW_ALWAYS so we can distinguish between using
global memory operators (usually OK) and #defining new to be
WXDEBUG_NEW (sometimes it might not be OK).
- Added time.cpp to makefile; set wxUSE_DATETIME to 1.
- Added a parent-existance check to popup menu code to make it not crash.
- Added some optimization in wxWindow::SetSize to produce less flicker.
It remains to be seen whether this produces any resize bugs.
It's a long time since I updated this file. Previously done:
- wxFrame, wxDialog done.
- wxScrolledWindow done (but backing pixmap not used at present).
- wxBitmap done though could be tidied it up at some point.
- Most basic controls are there, if not rigorously tested.
- Some MDI support (menus appear on child frames at present).
- wxNotebook almost done.
- wxToolBar done (horizontal only, which would be easy to extend
to vertical toolbars).
More recently:
- Colour and font changing done (question mark over what happens
to scrollbars).
- Accelerators done (for menu items and buttons). Also event loop
tidied up in wxApp so that events are filtered through ProcessXEvent.
- wxWindow::GetUpdateRegion should now work.
Alpha 16, September 8th 1998
----------------------------
wxMSW:
- Added wxSashWindow, wxSashLayoutWindow classes, and sashtest
sample.
- Guilhem's socket classes added, plus wxsocket sample.
- A few more makefiles added.
- GnuWin32/BC++ compatibility mods.
- Further doc updates.
- wxProp updates for correct working with wxGTK.
wxMotif:
- First start at Motif port.
- Made makefiles for wxMotif source directory and minimal sample.
- First go at wxApp, wxWindow, wxDialog, wxPen, wxBrush, wxFont,
wxColour, wxButton, wxCheckBox, wxTextCtrl, wxStaticText,
wxMenu, wxMenuItem, wxMenuBar
Alpha 15, August 31st 1998
--------------------------
wxMSW:
- wxBitmap debugged.
- wxDC::GetDepth added.
- Contribution added whereby wxBitmap will be
converted to DC depth if they don't match.
- wxConfig API improved, documentation updated.
- Printing classes name conventions cleaned up.
- wxUpdateUIEvent now derives from wxCommandEvent
so event can travel up the window hierachy.
Alpha 14, July 31st 1998
------------------------
wxMSW:
- Toolbar API has been simplified, and now
wxFrame::GetClientArea returns the available client
area when toolbar, status bar etc. have been accounted for.
wxFrame::CreateToolBar added in line with CreateStatusBar.
- Documentation updates, incl. for wxToolBar.
- New wxAcceleratorTable class plus wxFrame::SetAcceleratorTable.
- Various additions from other folk, e.g. streams, wxConfig
changes, wxNotebook.
- Added wxDocMDIParentFrame, wxDocMDIChildFrame for doc/view.
Alpha 13, July 8th 1998
-----------------------
wxMSW:
- Implemented wxPoint as identical to POINT on Windows, and
altered wxDC wxPoint functions to use wxPoint directly in
Windows functions, for efficiency.
- Cured wxASSERT bug in wxStatusBar95.
- #ifdefed out some bits in oleutils.cpp for compilers that
don't support it.
- Added some operators to wxPoint, wxSize.
- Added inline wxDC functions using wxPoint, wxSize, wxRect.
Alpha 12, July 7th 1998
-----------------------
wxMSW:
- Added wxApp::GetComCtl32Version, and wxTB_FLAT style, so can
have flat toolbars on Win98 or Win95 with IE >= 3 installed.
Alpha 11, July 3rd 1998
-----------------------
wxMSW:
- 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.
- Added Vadim's wxDataObject and wxDropSource.
- ENTER/LEAVE events now work.
- Cured wxMemoryDC bug where the DC wasn't being deleted.
- Cured wxGauge SetSize major bugginess.
- Cured problem where if a GDI object was created on the stack,
then went out of scope, then another object was selected into
the DC, GDI objects would leak. This is because the assignment
to e.g. wxDC::m_pen would delete the GDI object without it first
being selected out of the DC. Cured by selecting the old DC object
first, then doing the assignment.
- Split up wxGaugeMSW, wxGauge95, wxSliderMSW, wxSlider95
- Various other bug fixes and additions.
Generic:
- Major work on Dialog Editor (still plenty to go).
- Expanded documentation a bit more.
Alpha 10, May 7th 1998
----------------------
wxMSW:
- 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
------------------------
wxMSW:
- 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.
Generic:
- Corrected some bugs, such as the wxModule compilation problem.
- Added Gnu-Win32 b19/Mingw32 support by changing resource
compilation and pragmas.
- Changed SIZEOF to WXSIZEOF.
Alpha 8, April 17th 1998
------------------------
wxMSW:
- 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.

- Added samples/png.
- IMPORTANT: Changed 'no id' number from 0 to -1, in wxEVT_ macros.
Porters, please check particularly your wxTreeCtrl and wxListCtrl
header files.
- Added modules.h/cpp, config.cpp, fileconf.cpp, textfile.cpp/h.
Alpha 7, March 30th 1998
------------------------
wxMSW:
- 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.
Generic:
- Added tab classes, tab sample.
- Revised memory.cpp, memory.h slightly; memory.h now #defines
new to WXDEBUG_NEW in DEBUG mode. Windows implementation app.cpp
now checks for leaks on exit. Added memcheck sample.
See src/msw/issues.txt for more details.
- resource.h, resource.cpp changed to make wxDefaultResourceTable
a pointer. Now initialize resource system with
wxInitializeResourceSystem and wxCleanUpResourceSystem, to
allow better control of memory.
- wxString now derives from wxObject, to enable memory leak
checking.
- Added some #include fixes in various files, plus changed
float to long in wxToolBar files.
Alpha 6, March 10th 1998
------------------------
wxMSW:
- 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.
Generic:
- Added Vadim's dynarray.h, dynarray.cpp.
- Added Vadim's menuitem.cpp.
- Added Windows-specific wxCheckListBox,
owner-draw wxListBox, and drag-and-drop
(see docs/msw/changes.txt).
Alpha 5, 14th February 1998
--------------------------
wxMSW:
- 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.
Generic:
- GENERIC AND MSW-SPECIFIC CODE NOW TREATED AS TWO SEPARATE
DISTRIBUTIONS. This change log will therefore now refer to
the generic code only. See docs/msw/changes.txt for Windows-specific
changes.
- Readmes, change logs and installation files now go in
platform-specific directories under docs, e.g. docs/msw,
docs/gtk.
- Added DECLARE_APP and IMPLEMENT_APP macros so wxApp object gets
created dynamically, not as a global object.
- Put wxColour into wx/msw/colour.h, src/msw/colour.cpp.
- Changed names of some include/wx/generic headers to be
consistent and to conform to gcc pragma conventions. Also
changed choicesg.cpp to choicdgg.cpp.
- Added gcc pragmas.
- Added gtk inclusion in include/wx headers.
- Added consistent file headings to source and headers.
- Removed lang.cpp, lang.h and references to wxSTR_... variables;
added a few references to wxTransString.
- Added operator to wxTransString that converts automatically
to wxString, so we can say e.g. wxMessageBox(wxTransString("Hello"), ...).
- samples/internat now works (minimally).
- Added wxMouseEvent::GetPosition and
wxMouseEvent::GetLogicalPosition, both returning wxPoints.
- Made wxSize and wxRect contain longs not ints.
- Cured some lemory leaks (thanks Vadim).
- Tidied up OnIdle and introduced RequestMore/MoreRequested so
will only keep processing OnIdle if it returns TRUE from
MoreRequested.
Alpha 4, 31st January 1998
--------------------------
All:
- 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
-----------------------
All:
- 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
------------------------
All:
- 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
-----------------------
Generic:
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).
