In this screencast you see truly visually seamless blending of gtk+-widgets on top of a OpenGL-context. The whole UI is "one piece" and you don't see any "gaps" between the gtk+-widgets and the objects drawn with OpenGL. Actually everything is drawn via OpenGL, even the gtk+-widgets. They are texture-mapped onto quads. For obtaining the textures of the widgets the OpenGL-extension GLX_EXT_texture_from_pixmap is used. You see that this approach fully respects resizing, theme-changes and mouse- and keyboard input. For more info visit http://macslow.thepimp.net
