Parent drawing over Child window

Hi,

If I create a child window, is it possible for the parent to draw over
the child region (that is to say using the GC of the parent) ?
Are X11 drawing functions able to draw over an openGL window ?

greeting,

craouette

Yes, if the gc->subindow_mode is set to IncludeInferiors instead of
ClipByChildren.

already tried to call XSetSubwindowMode on the parent gc, but still,
my opengl window is in front, and the X drawing command does not seem
to affect the opengl subwindow...
any idea where I can find a sample code for this ?
