This allows a bitmap to scale with the size of the wxStaticBitmap control.
Scaling can be controlled to fill the control with or without changing the
bitmaps aspect ratio.
Add a couple of missing @name commands; the corresponding comments were
appearing in the wrong place without them.
Avoid unintended effects of JAVADOC_AUTOBRIEF by using Qt-style comments
instead of Javadoc.
A couple of minor wording corrections.
wxGridTableBase::SetAttr (for cells) does check its attr parameter for
nullptr, but the check was missing from the row and column functions.
Adding it makes it possible to use a nullptr argument to reset the
attributes.
Ensure that 32bpp bitmaps selected in wxMemoryDC use DIB for their internal
representation as GDI+ functions don't seem to work correctly with DDBs.
Note: Code responsible for converting and fixing the bitmap has been moved
from wxGCDCImpl::wxGCDCImpl to wxGDIPlusRenderer::CreateContext because this
is the common entry point for creating context for GDI+.
Closes#17324.
For some systems (like OS X, GTK+ 3) drawing with transparency is supporting by native wxDC and in this case "Alpha screen" sample can be shown even if wxGraphicsContext is not used/enabled. For such wxDC's all drawing operations can be done directly without using wxGraphicsContext.
Ignore the WinChange flag in DoNavigateIn() to fix an assertion that happened
when pressing Ctrl+Tab with the generic wxListCtrl having focus.
This seems to be consistent with pressing Ctrl+Tab elsewhere, e.g. when
cycling between buttons in a dialog.
These constants were defined in the middle of the wxKeyCode enum, value-wise,
which made it difficult to end new elements to the enum as they could clash
with the existing ones if they were simply added at the end.
The button label font and colour could be lost when its bitmap was set because
this could result in the recreation of the GtkLabel, internally.
Fix this by reapplying the styles to the possibly recreated label when
changing the bitmap or its position in the button.
Unchecking radio item makes no sense and wxMSW does nothing in this case, so
don't do anything in wxGTK neither, in particular don't generate a spurious
wxEVT_MENU.
Closes#17318.
Bitmap for the close button is scaled based on GetContentScaleFactor(). On OS X the resulting bitmap has to use the correct scaling factor in order to be displayed correctly on the button when using a high resolution display.
The low resolution (14x14) bitmaps scaled badly on high resolution displays. A close button suitable for usage inside a window (like wxInfoBar) is not available via HI theme drawing methods. This drawing code tries to emulate a close button, as close as possible to the one found in the Xcode 6+ welcome window.
Include wx/defs.h to get wxUSE_DIRDLG value from it, otherwise it could be
undefined, and hence evaluate to 0 (unfortunately without even a warning with
some compilers), if this header was the first wx header to be included.
We don't need to change the selection if we're interested in the attribute of
its starting position, as is typically the case because this is also the
cursor position, because EM_GETCHARFORMAT returns the attribute of the first
character of the selection and not, as was apparently believed when this code
was written, only the attributes which are the same for the whole selection.
This avoids flicker when constantly using GetStyle() to check for the format
at the cursor position as the selection is not changed all the time any more.
When converting internal bitmap to wxImage in wxGDIPlusBitmapData::ConvertToImage set up output alpha channel buffer only if source bitmap contains alpha channel values.
Get access to bitmap bits with IWICBitmap::Lock instead of IWICBitmapSource::CopyPixels because in-place processing is more effective in terms of speed and memory consumption (see IWICBitmap interface description in MSDN).
See #17311.
Save alpha channel retrieved from internal bitmap if target wxImage is capable to store it. Also undo premultiplication of RGB values if bitmap contains alpha channel values.
Closes#17311.
This symbol can now be predefined to avoid conflicts with mode_t definition in
wx/filefn.h when wxWidgets is used in applications also using another library
which also defines mode_t.
