2929.0. "Protecting Bit planes?" by SNOC02::ZAMBOTTIW (It only works after you ask!) Thu Jun 14 1990 06:43

    Hi people,
    
    can I protect bit planes in X so that draw requests can only affect the
    unprotected planes?
    
    An application I am porting sets aside two bit planes for drawing it's
    own pull down menus.  I thought this should be achievable by allocating
    two GC's with differently protected bit planes and use one GC for
    displaying the pull down menus and the other GC for other draw
    requests.
    
    Am I barking up the wrong tree or can anyone suggest a better
    alternative?
    
    Walter.

	You can do that. See the write mask argument in the GC. Burns
