WM_PALETTECHANGED
The WM_PALETTECHANGED message is sent to all top-level and overlapped windows
after the window with the keyboard focus has realized its logical palette,
thereby changing the system palette. This message enables a window that uses a
color palette but does not have the keyboard focus to realize its logical palette
and update its client area.
WM_PALETTECHANGED
hwndPalChg = (HWND) wParam; // handle of window that changed palette
Parameters
hwndPalChg
Value of wParam. Identifies the window that caused the system palette to change.
Remarks
This message must be sent to all top-level and overlapped windows, including
the one that changed the system palette. If any 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.
