You are missing a QLayout managing the dimensions of your QGraphicsView 
inside your QFrame, I think. Every widget that contains other widgets 
should manage the layout of those other widgets in some way. Normally, 
you'd use a QLayout derived class for that, but if you want, you can do 
it manually too, of course.
