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.
+
+
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
-- 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
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
- 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
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
+
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,
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
+ 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.
+
