Well I told you wrong :).
That's not QCanvasItem::move(), that's QCanvasItem::moveBy().
And it gets overriden many times.

But as Pino pointed me on IRC QGraphicsItem has itemChange() function which is 
virtual, can be overriden, and can be used to replace moveBy() so you're 
lucky :-). Take a look at it.

Cheers,
Dmitry.
