title: Scaling the QGraphicsScene to fill whole QGraphicsView
body: <p>I have found a few fixes for this issue, but none of seemed to be sufficient. I have a <code>QGraphicsView</code> displaying a <code>QGraphicsScene</code>. What I want to do is to scale the scene in order to fill the whole view. Also I want it to scale dynamically when the user will be resizing the window displaying the view. Is such a thing possible? If so I'd be glad if you could give me a short example on how should it be implemented. Thanks in advance.</p>
