README
The overlay example This example program shows how to use OpenGL overlays with the TQt OpenGL Extension. It contains a TQGLWidget with a relatively expensive redrawing operation, and rubber-band drawing in the overlay plane. Using the overlay has the advantage that the rubber-band may be drawn and erased without damaging the image in the main plane, so costly redraws are avoided.
