And the easiest way to do so (if you don't need a reference for your own 
purpose) is to add the graphicsview to the mainwindow as the central widget 
done via setCentralWidget. Which has the advantage that it automaticly adds 
your graphicsview as the central widget in the mainwindow so it gets sized to 
fill all available space and get resized when the mainwindow is resized...

Have fun,
