I use the occwindow from transparency demo and until now everything worked fine.
Now I started to move elements programmatically and that does not work. Well, the movement applied to the shapes works, but nothing happens on screen. I tried update(), updateView() and even direct call to paintGL() - the first both don't do anything and the last traps with "Default FBO wrapper creation failed".
When I use the mouse wheel to zoom in and out, I see the elements move - but only at the rate, I move the wheel.
What am I missing? How can I create a dynamic refresh rate, that is fast on action and sleeps if nothing happens?
When I move an element dragging with the mouse, there's no update/refresh problem. I can move as fast as I want - I see every move. Is it possible to simulate dragging with the mouse, so that I can achieve a smooth move?
