WM_PALETTECHANGED
A version of this page is also available for
4/8/2010
This message is sent by the OS to all top-level and overlapped windows after the window with the keyboard focus realizes its logical palette.
This message enables windows that do not have the keyboard focus to realize their logical palettes and update their client areas.
Syntax
WM_PALETTECHANGED hwndPalChg = (HWND) wParam;
Parameters
- hwndPalChg
Handle to the window that caused the system palette to change.
Return Value
None.
Remarks
This message must be sent to all top-level and overlapped windows, including the one that changed the system palette.
If child windows use a color palette, this message must be passed on to them as well.
To avoid creating an infinite loop, a window that receives this message must not realize its palette unless it determines that wParam does not contain its own window handle.
