Ah, well... this is something one could discuss. Goya will only  
trigger those paints when the view asks the delegate to paint itself,  
and in some special circumstances.

Actually, it doesn't trigger so many paint events. For instance, if  
you add a progress bar with Goya, and just do  
progressBar->setValue(foo); when foo has changed, the progress bar  
won't be updated in goya till you hover with the mouse, click or  
whatever. In this example the progress value should be stored somehow  
in the model, and when it changes, it should emit dataChanged what  
would trigger a repaint, so the progressbar becomes updated.

This is an example of how Goya "saves" repaints.
