/* palette related msgs's:
|
|
- WM_ACTIVATE:
|
|
The WM_ACTIVATE message is sent when a window is being activated or
|
|
deactivated. This message is sent first to the window procedure of
|
|
the top-level window being deactivated; it is then sent to the
|
|
window procedure of the top-level window being activated.
|
|
|
|
- WM_QUERYNEWPALETTE:
|
|
The WM_QUERYNEWPALETTE message informs a window that it is about
|
|
to receive the keyboard focus, giving the window the opportunity
|
|
to realize its logical palette when it receives the focus.
|
|
|
|
If the window realizes its logical palette, it must return TRUE;
|
|
otherwise, it must return FALSE.
|
|
|
|
- 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.
|
|
|
|
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.
|
|
|
|
- WM_SYSCOLORCHANGE:
|
|
The WM_SYSCOLORCHANGE message is sent to all top-level windows when
|
|
a change is made to a system color setting.
|
|
|
|
- MTK_WM_PALETTE:
|
|
Internal msg. Uses:
|
|
- In fullscreen mode, we send this from Main wndproc to main
|
|
window's children on WM_ACTIVATE.
|
|
- When this is received in SS_ScreenSaverProc, if fullscreen,
|
|
it does:
|
|
UnrealizeObject( pssPal->hPal );
|
|
RealizePalette( hdc );
|
|
otherwise, it is passed to PaletteManageProc, where
|
|
Realize is called (for 'floater' windows to realize
|
|
their palettes).
|
|
- It is also sent by DelayPaletteRealization() when it can't get
|
|
the system palette.
