Hi, I am trying to use Qt OpenGL widgets as a HUD for OSG. (Wow, I love abbreviations!)
[url]http://labs.trolltech.com/blogs/2008/06/27/accelerate-your-widgets-with-opengl/[/url] I have managed to get Qt to draw its widgets over OSG, and it looks good. First I let OSG draw its scene, then Qt renders its widgets. The only problem is that OSG does a buffer swap when it is finished drawing. This causes a flicker effect. I cannot find a way to convince Qt to draw its stuff at a specific point, so adding a post-render callback to OSG does not work. So is there a way to turn off buffer swapping? I could not find any way in the source (without modifying window system specific stuff). Any help is appreciated. Thanks!
