Use wide-char versions of debug help functions if available, falling back to
the narrow char ones otherwise.
Also improve 64 bit support by using 64 bit versions of the functions if
available as well.
Closes#15138.
Don't let unhandled Win32 (i.e. structured) exceptions escape from wxWndProc()
as they can just disappear into thin air when running under WOW64 as 32 bit
exceptions can't propagate through 64 bit kernel. So catch them immediately
and pass them to the global handler while we have the chance to do it, as
we're never going to get it in the outer __try/__catch block in wxEntry() in
src/msw/main.cpp.
In particular, this allows to catch crashes in wxEVT_PAINT handlers, such as
the one in debughlp sample, again.
Closes#16656.
This method doesn't really have to be virtual and this change will allow to
backport the commit adding wxIconizeEvent generation to 3.0 branch.
See #16718.
wxPG_NULL_BITMAP macro is not useful because is used only once. In the rest of wxPG code wxNullBitmap is used explicitly many times so for the sake of consistency we can resign from using this macro.
If the old value didn't lie inside the new range, it was changed by the native
control internally but the value stored by wxDatePickerCtrl itself remained
unchanged, resulting in asserts later when the mismatch between them was
detected.
Closes#13189.
The fix to the length allocated for the buffer (which was off by 1) in
wx2stc() in 9f81ac16f0 exposed another bug,
which used to compensate for that one, in wx2stclen(), so fix it too.
See #16776.
Events are not needed for this kind of sockets, using wxSOCKET_BLOCK is
supposed to ensure that calling socket IO operations blocks until the bytes
are read/written without dispatching any events.
See #17031.
Call wxPropertyGridpageState::DoSelectProperty with explicitly set flags instead of casting from bool to unisgned int. It cannot be guaranteed that 0/1 values of this implicit conversion will be mapped to the proper flags also int the future.
Implement Freeze() by blocking the GtkWindow "expose-event"/"draw" signal
instead. Since the introduction of client-side windows in GTK+ 2.18,
gdk_window_freeze_updates() is unuseable because the impl_window (and thus the
update_freeze_count) for a given GdkWindow can change unpredictably. See #16795
Its value (0x80000000) is outside of the int type range on 32 bit platforms,
but we still want to allow using it as an initializer of int and/or long
variables for consistency with the other types, so cast it to int explicitly
to suppress -Wnarrowing warnings from recent g++ which were given when doing
this before.
Allow a library and an application to differ in __GXX_ABI_VERSION
within the range 1002-1008. The ABI changes made in this range
do not affect wxWidgets.
Declare _hypot() function globally, predefining __NO_INLINE__ in wx/math.h is
not enough as <math.h> is also included from some other standard headers, e.g.
<algorithm>, and including them results in the same bug as in wx/math.h
(i.e. https://sourceforge.net/p/mingw/bugs/2250/).
Including standard math.h header with both -O2 and -std=c++NN options results
in compilation error due to a bug in the header, see MinGW bug report at
https://sourceforge.net/p/mingw/bugs/2250/
Work around this to allow the library to compile in release build with
-std=c++11. This is ugly but better than failing to compile at all.
These options enable "strict ANSI" mode in MinGW which omits declarations of
POSIX functions from the standard headers. To allow the library and, possibly
even more importantly, the user code including our headers, to compile with
these options, declare the functions that we need ourselves.
This might appear to go against the spirit of "strict ANSI" mode, but the only
alternative would be to not use such functions at all and silently cripple the
library when -std=c++NN is used, compared to -std=g++NN case, and this doesn't
seem appealing neither.
Closes#16984.
Currently, customizing some dialogs for small screen environment is done statically on the build stage by setting wxPG_SMALL_SCREEN to 1 (what is done for WXWINCE only).
Instead, we can do this for all platforms in a dynamic manner, based on the classification provided by wxSystemSettings::GetScreenType() function.
In order to do so there is introduced a static helper function wxPropertyGrid::IsSmallScreen() which is used to select right parameters (size, position) for several dialogs in order to display them correctly on the small screen.
Apparently in some versions of the compiler even simply dereferencing a
pointer inside typeid() still provokes -Wpotentially-evaluated-expression.
Avoid this by dereferencing it outside and only using typeid() with
references.
Closes#16968.
This simplifies the code and fixes the bug with GetItemCount() returning wrong
(old) value in wxEVT_LIST_INSERT_ITEM event handler as m_count wasn't updated
by then yet.
Closes#3793.
This deprecated method was never actually defined, so could never be used. The
fact that nobody complained about it would seem to be an indication that it is
not used anywhere, so just remove it.
See #17007.
