Because QAbstractScrollArea::resizeEvent, as documented, is supposed to be 
called when the viewport is called.
This is the behaviour of QAbstractScrollArea with most event.  you can 
intercept viewport event form the widget itself. 
One can argue if it is a good idea, but it has been like that since Qt 4.0 and 
is not going to change now.
