It's unexpected that decreasing the width of the control makes the last
column diminish in size until nothing (at least if it's minimum size was
not set), instead of showing horizontal scrollbar, so prevent this from
happening by considering the initial column width as being "manually
set", which prevents the code from making the column narrower than it
automatically.
This seems to make sense and is consistent with the handling of initial
size, which becomes "best", and hence "minimal", size of the control,
for wxWindow.
Closes#18343.
When running under Wayland and using two-finger scrolling, GTK seems to only
emit "smooth" scrolling events. The code was already setup to handle
GDK_SCROLL_SMOOTH events - we just needed to add GDK_SMOOTH_SCROLL_MASK to the
event mast of the window in order to receive the events.
Fixes#17734.
To preserve layout, old wxComboBox should be replaced with the new one in the same location in the sizer. So we need to create a new combo box first, put in the sizer and only after that the old combo box can be deleted.
Checking whether alpha info flag contains one of
the constants representing image/bitmap with alpha
channel is done more than once in the code so this
check can be moved to a dedicated function.
This makes the collapsible pane allocated exactly its best size better
looking, as the header is centered now, instead of having a border on
the left side, but not on the right one.
See #18515.
DoGetBestSize() actually calculated the best client size and not the
full size, as it didn't take the pane border into account.
Fix this in the simplest possible way, by just renaming the function to
DoGetBestClientSize() instead.
This ensures that the pane is actually big enough to show its contents,
without cutting off the text shown in its header.
Closes#18515.
Make it more clear that we do what we do in DoGetBestClientSize()
because of what our OnPaint() does.
Incidentally fix off by 1 (or 2 under non-MSW platforms) mismatch
between the 2 methods: the gap between the button and the text is
actually just 2 DIPs, not 4, but we need to add another 1 DIP for the
focus rectangle under MSW.
This symbol can be predefined to use the libraries built with "vc14x" as
the compiler prefix. This can be useful to reuse the same binaries for
all ABI-compatible VC 14.x versions: 14.0 (MSVS 2015), 14.1 (2017) and
14.2 (2019).
Extend the description of library selection symbols used with MSVC to a
more general discussion of MSVC-specific symbols and document the
symbols affecting compiler prefix in this section too.
At least mention wxGraphicsContext and Bind() instead of only speaking
of wxDC and event tables.
Also mention sizers.
Do _not_ mention obsolete and deprecated wxList and friends.
Since wxBitmap can have both alpha channel values and mask we have to use
alpha channel (if required) in the sub-bitmap even if the mask is provided
too.
See #18513.
In the function wxMask::OSXCreate() to create a mask image, data copying
from the supplied memory buffer was not actually implemented and therefore
created mask was invalid.
Closes#18513.
Notably mention that showing modal dialogs won't work in this case.
Also link to this explanation from wxListCtrl documentation as
wxEVT_LIST_ITEM_SELECTED is one of the perhaps less expected cases in
which this problem arises.
See #9973.
Use setCurrentText(), which works for non-editable combo boxes as well
as for editable ones, instead of setEditText(), which only works for the
latter ones.
Closes https://github.com/wxWidgets/wxWidgets/pull/1542
Check that adding a window to either the same, or different, sizer the
second time asserts -- but that it can still be moved to another sizer
if it is detached from the first one first.
Also document that SetContainingSizer() should never be called from
outside the library.
See #17166.
