GraphicsView performance problems

[camel]

Gopal, u made a small mistake, and i wonder why it wasnt caught...u were drawing out of the boundingrect !!

No actually he was not. The bounding rect you created was much too large. You only have to specify the bounding rect of the current item. You seem to want to include additionally the bounding rects of the child items.

see the performance difference urself... !!!

The reson for the perfomance advantage in this case can be seen in my analysis a few posts up.
