------- Additional Comments From philip@digitalinfinity.biz 2006-23-04 10:13 ------- Question for you. Can libGL draw on drawable types in X or is it just an XWindow it can draw on. I mean there are other drawable types, off screen types, that the drawing functions in X can draw on. If libGL allows you to draw on those then you can just have the functions draw on the drawable and then transpose the drawable on the Wine window. Although this will probably hurt performance more then help it. Your probably better off with a proxy object that acts like a wine window but is an X Window.
I must admit I do need to learn more about the windows MDI functionality for me to be of further assistance on this. I have no idea how the MDI GL windows work in windows to offer any further ideas.
