Collision detect in QGraphicsScene

[aamer4yu]

But, it seems there is no such event as far as I can see.

Even if there was such event, it would internally need to monitor items movement at regular intervals...
By the way in 4.6 theres also sub attack example...but I gues thats done using animation framework..dont know how collision detection is used in it..
may be u can check and let us know
