This allows to determine if dark mode is enabled (for the applications and/or the system UI itself, respectively) system-wide which is useful now that IsDark() returns false unless MSWEnableDarkMode() is called. Also document the incompatible change to IsDark().

INCOMPATIBLE CHANGES SINCE 3.2.x:
|
|
=================================
|
|
|
|
Changes in behaviour not resulting in compilation errors
|
|
--------------------------------------------------------
|
|
|
|
- wxMSW now uses double buffering by default, meaning that updating the
|
|
windows using wxClientDC doesn't work any longer, which is consistent with
|
|
the behaviour of wxGTK with Wayland backend and of wxOSX, but not with the
|
|
traditional historic behaviour of wxMSW (or wxGTK/X11). You may call
|
|
MSWDisableComposited() to restore the previous behaviour, however it is
|
|
strongly recommended to change your redrawing logic to avoid using wxClientDC
|
|
instead, as the code using it still won't work with wxGTK/wxOSX.
|
|
|
|
You may also choose to globally set the new msw.window.no-composited system
|
|
option to disable the use of double buffering, but please consider doing it
|
|
only as a last resort and/or temporary solution, as this _will_ result in
|
|
flicker and won't be supported at all in the future wxWidgets versions.
|
|
|
|
- wxMSW doesn't support versions of Microsoft Windows before Windows 7. If you
|
|
need Windows XP or Vista support, please use wxWidgets 3.2.
|
|
|
|
- As first mentioned in 3.0 release notes, the value of wxTHREAD_WAIT_DEFAULT,
|
|
used by wxThread::Delete() and Wait() by default, has changed from
|
|
wxTHREAD_WAIT_YIELD to wxTHREAD_WAIT_BLOCK for safety and consistency.
|
|
|
|
- wxDocument::OnCloseDocument() was called twice in previous versions when
|
|
closing the document from the menu. Now it is only called once and after
|
|
destroying all the existing document views. If you overrode this function,
|
|
please check that you don't rely on any views existing when it's called.
|
|
|
|
- wxGrid::FreezeTo() now asserts when passed invalid (out of range) number of
|
|
rows or columns to freeze. But it also does freeze the requested rows/columns
|
|
even if the grid is currently too small to show all of them or if there are
|
|
no unfrozen rows/columns remaining.
|
|
|
|
- Calling wxImageList methods on an invalid wxImageList object now consistently
|
|
results in assert failures instead of just failing silently. To avoid these
|
|
asserts, make sure that wxImageList is created with a valid size before
|
|
operating on it.
|
|
|
|
- wxTRANSPARENT_WINDOW doesn't do anything and shouldn't be used any more. If
|
|
you ever used it under MSW (it never did anything in the other ports), you
|
|
can turn on the native WS_EX_TRANSPARENT extended style if really needed.
|
|
|
|
- wxSystemAppearance::IsDark() now returns whether this application uses dark
|
|
mode under MSW, use the new AreAppsDark() or IsSystemDark() to check if the
|
|
other applications or the system are using dark mode.
|
|
|
|
|
|
Changes in behaviour which may result in build errors
|
|
-----------------------------------------------------
|
|
|
|
- Symbols deprecated in 3.0 are still available in this version but disabled by
|
|
default, you need to set WXWIN_COMPATIBILITY_3_0 to 1 to enable them. Symbols
|
|
deprecated in 2.8 are not available any longer.
|
|
|
|
- Building with wxUSE_UNICODE=0 is not supported any longer.
|
|
|
|
- wxMotif and wxGTK1 ports have been removed, please use wxWidgets 3.2 if you
|
|
still need them.
|
|
|
|
- Generic wxSearchCtrl doesn't provide methods that make sense only for
|
|
multiline text controls any longer, for consistency with the other ports.
|
|
|
|
- wxOnAssert() overload taking wide character file name was removed. If you
|
|
call it for any reason, please use one of the other overloads instead.
|
|
|
|
|
|
3.3.0: (released 2022-??-??)
|
|
----------------------------
|
|
|
|
NOTE: In addition to the note below, also incorporate (either by
|
|
copy or by reference) all the changes in the 3.2 branch (i.e.
|
|
everything in this file after 3.2.0 in that branch).
|
|
|
|
NOTE: This file is updated only before the release, please use
|
|
|
|
$ git log --notes=changelog --format='%N' v3.2.0..|grep .
|
|
|
|
to see all the change log entries since the last release.
|
|
|
|
To update the notes, fetch them first:
|
|
|
|
$ git fetch origin refs/notes/changelog:refs/notes/changelog
|
|
|
|
then use the following command to update them locally
|
|
|
|
$ git notes --ref=changelog add -m 'wxPort: description.'
|
|
|
|
and finally push it to the server.
|
|
|
|
$ git push origin refs/notes/changelog:refs/notes/changelog
|
|
|
|
If this fails due to a conflict because you had forgotten to
|
|
run git-fetch first, you can always reset your local notes
|
|
(LOSING YOUR CHANGES TO THEM, so make sure to make a copy)
|
|
|
|
$ git fetch origin refs/notes/changelog
|
|
$ git update-ref refs/notes/changelog FETCH_HEAD
|
|
|
|
and then redo "git-notes add" and git-push.
