INCOMPATIBLE CHANGES SINCE 2.2.x
================================
+ Please take a few minutes to read the following list, especially
+ paying attention to the most important changes which are marked
+ with '!' in the first column.
+
+ Also please note that you should ensure that WXWIN_COMPATIBILITY_2_2
+ is defined to 1 if you wish to retain maximal compatibility with 2.2
+ series -- however you are also strongly encouraged to try to compile
+ your code without this define as it won't be default any longer in
+ 2.6 release.
+
+ NB: if you want to build your program with different major versions
+ of wxWindows you will probably find the wxCHECK_VERSION() macro
+ (see the documentation) useful.
+
+
wxBase:
-- wxArray<T>::Remove(size_t) has been removed to fix compilation problems
+! 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
+! 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.
by all derived classes, if you have user-defined event classes please
add "wxEvent *Clone() const { return new MyEvent(*this); }" line to them
+- 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)
+
+- another minor change: wxApp::OnAssert() has a new "cond" argument, you
+ must modify YourApp::OnAssert() signature if you were using it to override
+ the default assert handling.
+
All (GUI):
-- the event type constants are not constants any more but are dynamically
+! 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
+ but this is strongly discouraged, please consider changing your code
instead!
-- wxDialog does not derive from wxPanel any longer - if you were using it in
+! 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.
+ the occurrences of wxPanel with wxWindow.
+
+! if you handle (and don't skip) EVT_KEY_DOWN, the EVT_CHAR event is not
+ generated at all, so you must call event.Skip() in your OnKeyDown() if
+ you want to get OnChar() as well
+
+- in general, the key events sent for the various non ASCII key combinations
+ have been changed to make them consistent over all supported platforms,
+ please see the wxKeyEvent documentation for details
- 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
if ( flags & wxYES )
... do something else ...
+- static wxWizard::Create() doesn't exist any more, the wizards are created
+ in the same way as all the other wxWindow objects, i.e. by directly using
+ the ctor
+
- 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
+- 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
+
+- several obsolete synonyms are only retained in WXWIN_COMPATIBILITY_2_2 mode:
+ for example, use wxScrolledWindow::GetViewStart() now instead of ViewStart()
+ and GetCount() instead of Number() in many classes
+
+- wxCmdLineParser does not use wxLog to output messages anymore.
+ to obtain the previous behaviour, add
+ wxMessageOutput::Set(new wxMessageOutputLog); to your program
+ (you will need to #include <wx/msgout.h>)
+
wxMSW:
-- build system changed: setup.h is not a static file in include/wx any more
+! 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.
+ class. You'll need to remove all references to xpm.lib from your
+ make/project files. Finally, the library names have changed as well and now
+ use the following consistent naming convention: wxmsw[u][d][ver].(lib|dll)
+ where 'u' appears for Unicode version, 'd' -- for the debug one and version
+ is only present for the DLLs builds.
- 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
+ style to avoid it
- 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
+! 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.
+wxThread and related classes:
+
+- The thread-related classes have been heavily changed since 2.2.x versions
+ as the old code had many serious problems. This could have resulted in
+ semantical changes other than those mentioned here, please review use of
+ wxThread, wxMutex and wxCondition classes in your code.
+
+! 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 it was impossible to ensure the correct behaviour
+ (i.e. absense of race conditions) using the old API.
+
+- wxMutex is not recursive any more in POSIX implementation (it hasn't been
+ recursive in 2.2.x but was in 2.3.1 and 2.3.2), please refer to the class
+ documentation for the discussion of the recursive mutexes.
+
+- wxMutex::IsLocked() doesn't exist any more and should have never existed:
+ this is was unique example of a thread-unsafe-by-design method.
+
