gdk_window_at_pointer

[Mathieu Malaterre <Mathieu Malaterre creatis insa-lyon fr>]

Hi gtk guru,

        I hope my question won't sound too weird, but I am *really* stuck.

	I want to know when a 'gdk_window_at_pointer' call could freeze my X 
session ? I even loose the ability to switching to a console (C+Alt+F1 
...). Before calling it should I check something ?

	BTW if I call 'gdk_flush' (which is BTW a XSync call), the X freeze 
deseapear. But I don't see why I should call this function. Don't take 
me as arrogant but if I should not add gdk_flush this is because it's 
inside the code of wxWindows (which should be safe).

	That said I am working on a class that would link wxWindow (ie wxGTK 
for my case) to VTK (see vtk.org for more info). You'll find the 
beginning of my work on:

	I don't think this could be usefull for you, anyway this was only to 
give a context to my question.

thank a lot if you could give me any advice.
sincerely,
mathieu
