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.


hwndPalChg = (HWND) wParam; // handle of window that changed palette 



Value of wParam. Identifies the window that caused the system palette to change.


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.
