Hello,

I've read the documentation for QGraphicsScene but unfortunately I don't understand a central point:

I have a look at this constructor:
Qt Code: 
  1. QGraphicsScene(double x, double y, double width, double height, QObject parent)
To copy to clipboard, switch view to plain text mode 

Whats the difference between x and width and y and height? I thougt that I have a "virtual table" (the QGraphicScene) on which I can put my items. But for that I would just have to give two dimensions, width and height. What do I need the other dimensions x and y for?

Thanks for your patience explaining this basic thing to me!
