Hey
I've created my own QGraphicsItem - curve to do some drawing but whenever I zoom close the curve disappears.
What function do I have to inherit/extend to handle visibility draw call?
Regards

It appears that QGraphicsScene checks if position of item is visible in view and then draws/dont draws it... returning qgraphicsScene->sceneRect() as boundingRect on my curve "solved" the issues but its a problem for selectable items... hmmm
