I've only got a passing familiarity with OpenGL, but I'll guess... If you are doing a screen capture via OpenGL, you'll probably want to create your own context (with direct GLX calls), rather than using the one provided by your widgets API (Qt/Gtk). You will probably need to base it off of the root window. -- Boyd Stephen Smith Jr. ,= ,-_-. =. b...@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
