Previously this was only done when wxBU_AUTODRAW was specified, making
this the only place in wxWidgets where this style was actually used.
This was not ideal, as the same code, not using wxBU_AUTODRAW, worked
just fine under MSW and GTK, but created ugly-looking buttons under Mac,
so do the right thing by default and let people call SetMargins(0, 0) if
they really don't want to have any margins.
Closes#18170.
This fixes a compilation error in wxMSW private fonts support
implementation, which compares wxString with a wide string but, unlike a
local fix there, makes sense more broadly and should reduce the
likelihood of similar errors in the future.
It also makes comparisons with narrow C strings more efficient in the
default, Unicode, build by using wxString::Cmp() method instead of
creating a temporary wxString, as was done before.
See #18172.
As usual, when changing the background colour, we need to change the
foreground as well, otherwise the text risks becoming unreadable with
some default text colour values -- as was the case under GTK+ 3 with its
default theme.
Due to https://bugzilla.gnome.org/show_bug.cgi?id=710888 GtkInfoBar
wasn't shown if it had been hidden before -- which is exactly what
wxInfoBar did.
Fix this using the workaround proposed in the bug report, which makes
the info bar appear immediately, without any transition, which might be
not ideal, but markedly better than failing to show it at all.
While this doesn't make, and never made, any sense (pointers should be
stored in a plain, non-object array), we still should continue to
support it for compatibility.
Fix the problem introduced by 97684a9267
by writing "T const&" instead of "const T&" as the latter didn't have
the same meaning when the macro parameter "T" expanded into "U*" as
"const" applied to "U", making this type incompatible with the actual
one.
Also extend the unit test to check for this.
Changing item cell in ShowAsRadio() was wrong as the item cell doesn't
exist when it is called and changing the column cell didn't seem to work
well, so just recreate the entire cell in it instead.

Avoid stringop-overflow warning about strncpy size argument depending on source size.
Checking for null in src is not needed because it is already checked by strlen.
This allows showing radio buttons in wxDataViewCtrl easily and natively.
Notice that this approach, adding an extra function to the existing
renderer class instead of creating some new wxDataViewRadioRenderer (see
https://github.com/wxWidgets/wxWidgets/pull/809), was finally chosen
because it is simpler to implement and, more importantly, because it
will be more natural to generalize if/when we also add a 3-state
check/radio renderer.

Changes of c0b0562533 to common code broke
wxGTK1 build, as wx/gtk/private/wrapgtk.h is for wxGTK 2+ only.
Fix this by handling wxGTK 1 separately and including gtk/gtk.h directly
for it.
Hopefully this code will be removed, together with the rest of wxGTK1
support, in some not so distant future.
This is especially important under MSW, where the modality of the nested
event loops actually ends as soon as wxModalEventLoop::Exit() is called,
and so we must avoid dispatching any events in the current loop after it
happens or we risk reentering the same loop again, which could result in
e.g. parent modal dialog being closed before the child event loop
returns (because the event closing the former was dispatched from the
latter) and other unexpected sequences of events.
To prevent this from happening, only dispatch pending events after the
loop exit if it's the outermost loop, as there should be no danger in
doing it in this case. Conversely, we don't lose anything by not doing
this in nested event loops as the outer loop will take care of any
remaining pending events anyhow.
To make this work in an ABI-compatible way, add a global counter of the
currently existing event loops which is used to check if there is more
than one event loop currently running.
Closes#11273, #11573, #11269.
Don't leave "m_hover" invalid if the number of columns in wxHeaderCtrl
is reduced, as this would result in a crash later when it is used.
This notably fixes a crash after removing the last column from generic
wxDataViewCtrl.
Closes https://github.com/wxWidgets/wxWidgets/pull/852
It was too high otherwise, which was especially noticeable in high DPI.
This is still not perfect, as the default search bitmap is not centered
neither and is a couple of pixels too high, but better than before.
Apply DPI scaling to the extra vertical margin added by this macro to
the font height.
This makes sense and results in wxTextCtrl (and other controls, e.g.
wxSearchCtrl) having the same height as native ones when using high DPI
too.
Note that this required adding wxGetEditHeightFromCharHeight() function
as one of the existing uses of EDIT_HEIGHT_FROM_CHAR_HEIGHT() wasn't
inside a wxWindow-derived class method and also adding wxUSE_GUI guard
around these GUI-only definitions as a function, unlike a macro, can't
be compiled without full wxWindow declaration in scope.
There is no need to override this virtual function, if the control size
changes, a wxEVT_SIZE event is generated in any case, resulting in a
call to LayoutControls() without explicitly calling it from here.
There doesn't seem to be any reason to have these flags, which duplicate
the visibility state of m_searchButton and m_cancelButton respectively.
Also update the buttons visibility immediately in ShowSearchButton() and
ShowCancelButton() instead of doing it in LayoutControls() as before,
which was confusing as laying out is not supposed to show/hide anything.
Finally, return true, not false, from IsSearchButtonVisible() if the
button is actually visible because there is an associated menu, even if
ShowSearchButton(false) had been called. This seems more logical and
makes the code simpler, but we need to check whether the native Mac
version also behaves like this or not.
No other changes in behaviour.
Replace LIGHT_STEP macro and 20 magic number with
SEARCH_BITMAP_LIGHTNESS and CANCEL_BITMAP_LIGHTNESS constants which are
a bit more clear, hopefully.
No real changes.
Make this button of exactly the bitmap size instead of using the full
control height for it, even if/when the bitmap is smaller.
This fixes some random junk being shown in the bottom two pixels of the
search button sometimes: this was due to only redrawing the part covered
by the bitmap in wxSearchButton::OnPaint(), leaving the rest of the
button unpainted (because wxSearchButton uses wxBG_STYLE_PAINT).
Checking for the exact match of __GXX_ABI_VERSION created more problems
(including for both Fedora and Debian packagers, see
https://github.com/wxWidgets/wxWidgets/pull/828) than it solved
(approximately 0), so relax it and assume that future g++ versions will
remain broadly compatible with the current ABI, which seems like a safe
assumption so far.
It's not really clear if there is any value in having this ABI check at
all, or if we should remove CheckBuildOptions() and all the code calling
it entirely, as it seems that there is no way to trigger this check
during run-time without getting a link error first. But keep it for now,
just because it's simpler to keep it than to remove it.
