468.0. "Top Window" by 22082::SHAH (DECwindows Technical Support) Thu Mar 23 1989 12:05

Hiya all,

Is there a way of finding out if a specific window is at the top of the stack?
This top window doesn't necessarily have input focus.  Is there something that
I can check in the window manager?  I've searched for various titles but 
haven't found anything.  If another note describes the solution, please 
point me to that....

Thanks,
-Pratish Shah

468.1Use Visibility Notify EventsLDP::WEAVERLaboratory Data Products/ScienceThu Mar 23 1989 15:346
    Visibility notify events should let you keep track of it, I don't
    know if there is any way to query the current state (it could change
    out from under you any way).

468.2Problems with Visibility Notify22082::SHAHDECwindows Technical SupportMon Mar 27 1989 10:2610
I created a simple program to use the Visbility Notify event, but I seem to be 
having some problems.  This application seems to only generate the event 
whenever I iconize and de-iconize a window.  There's no event generated when
I push the window back or partially cover it with another window.  Does a 
Visibility Notify event get generated during these actions?

Thanks,
-Pratish
468.3CirculateNotify is the correct eventLDP::WEAVERLaboratory Data Products/ScienceMon Mar 27 1989 18:0310
    Sorry, you want CirculateNotify events, not Visibility events, I
    misinterpreted the original request.  Use StructureNotifyMask or
    SubstructureNotifyMask.
    
    All of this is documented in the "X WINDOW SYSTEM C library and
    Protocol Reference" published by Digital Press and orderable online
    through DECdirect (EY-6737E-DP).

468.4Have same questionAVIATE::SHAHYanks in '89Wed Jul 12 1989 08:0512
	Since the last reply, I haven't had time to try out any solutions.
	CirculateNotify event only gets generated when the application calls
	XCirculateSubwindows** routines.  So if a user brings a window to
	the front by pressing on the title bar this event doesn't get 
	generated.  I may have misunderstood something??  Is there a way
	of getting the stacking order from DECwindows or do I have to
	keep track of this information myself....

	Thanks,
