He uses Qt for everything else, like mapping windows from the windowing system, input event management, etc. Also, note I said "design with OpenGL in mind", not "design with OpenGL". So what needs changing is the way of thinking, not necessarily the code itself. Using OpenGL and repainting everything from scratch with a lot of CPU calculation is not going to help. The point is that if you need the performance of graphics, you need to use the GPU the way the GPU is designed. Reduce your CPU work and use more retained settings across frames. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
