If it is not initialised, getting the screen rectangle will fail, so
don't even try doing it, but just return wxNOT_FOUND instead, so the
main display will be used -- this is the best we can do if the window
hasn't been created yet, as we don't know on which display it will
appear.

The changes of 5873ee7e4a completely broke
AUI layout as wxAUI code relies on Layout() still performing the layout
even when GetAutoLayout() returns false, but the new wxTLW::Layout()
didn't do anything in this case.
Fix the problem by checking whether we have a sizer or constraints in
this function instead of using GetAutoLayout(), which is supposed to
only be used by wxEVT_SIZE handler to determine if Layout() should be
called in the first place, but not by Layout() itself.
Closes#18486.
Since we always convert wxImage to 32 bpp wxBitmap, there is no reason to keep a separate mask for wxBitmap because alpha channel can be used directly.
Monochrome mask bitmap should have white pixels in the unmasked area and black pixels in the masked area, quite the opposite to what is implemented now.
Closes#10098.
When bitmap data are accessed with wxNativePixelData, which is designed
to handle RGB bitmaps, Alpha() function cannot be used because in this
case alpha component index is set to the default value -1 and actually
the blue component of the "preceding" pixel is accessed.
Closes#18478.
It's generally wxWidgets policy not to include platform-specific headers from our own
to avoid namespace pollution issues, in this case with names like "None" and "Window".
Getting the warnings about deprecated macros when building the library
itself is not useful, as it must continue to use them as long as
WXWIN_COMPATIBILITY_3_0 exists.
Closes https://github.com/wxWidgets/wxWidgets/pull/1510
While feacaf8714 changed the API to allow
using any wxWindow (and not only a window of a wxControl-derived class)
as the associated window of the grid editor, actually doing resulted in
an immediate crash due to dereferencing a null pointer in wxGrid code
which still expected to have a wxControl.
Fix this by replacing all calls to wxGridCellEditor::GetControl() inside
wxGrid with wxGridCellEditor::GetWindow(), to ensure that a non-null
editor window is used even in this case.
Closes https://github.com/wxWidgets/wxWidgets/pull/1509
It doesn't make sense to return anything else than an empty rectangle
when querying the icon rectangle of the sub-items that can't show any
icon.
Also document this behaviour, just in case it's not obvious.
