Hi,

I'm using one gfx display window for a 2D map in addition to the 3D
Performer window in my application. The 2D map is drawn on an OpenGL
glwMDrawingArea widget. My problem is that I can't seem to find any
functions that let me read the current display and window targets for
the GL calls. When I use:

glXMakeCurrent(XtDisplay(_glMapArea), XtWindow(_glMapArea), glxcontext);

..to set my 2D map as a window, I end up with the 3D Performer
graphics over my drawing area widget because I don't reset the current
context to the one used by Performer. How can I do this?

Any solution to this problem would be very much appreciated.

Morten
