In that case, perhaps a QApplication::processEvents() call is all you need. I 
am not a big fan of using it in the general case, but to make sure your 
warning for a short freeze is actually painted, perhaps it would be a 
solution. A better way is of course to make sure that your UI simply does not 
become unresponsive, not even for a short while. However, I realize that that 
is not always feasable.
