Hmm, the paint() function looks ok, so I'm not sure what's going wrong. 
Perhaps try commenting out the call to showRealWidget() in the paint 
function, and see if that helps. It might not be a good idea to call 
setCurrentWidget or setVisible etc during the paintEvent(). You could 
try to use a single shot timer to delay the call to showRealWidget().
