The GraphicsView looks great!

Now I'm trying to figure out how much work it's going to take to port to the QCanvas stuff to QGraphicsView.

In Qt 4.2 how does one tell a QGraphicsItem to move by a certain amount per update?
I'm looking for something equivalent to setXVelocity() in the QCanvasItem class.

I didn't see anything that seemed to resemble it in the docs:
