 The overlay example
 
 This example program shows how to use OpenGL overlays with the TQt OpenGL
-Extension. It contains a QGLWidget with a relatively expensive
+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
