I've got an MFC MDI app with openGL rendering in the one and only view class. When I have say 4 child frames open, the one that is active renders no problem, but the others are halted (the GL animation stops because the view is not being drawen by windows) How can I have all the child frame views constantly being drawen? The effect would be say 4 triangles spinning constantly no matter how they are tiled or moved around inside the parent. Thanks. [edited by - code_evo on May 25, 2004 9:55:47 PM]
