Well first of all im still a newbie at Qt so i hope im not asking anything blatantly obvious. That said let's move to the problem...
Im writing a game similar to Pong (bouncing the ball around the screen and into blocks) and i dont know how to implement ball's collision detection.
First of all if using the collidingItems method i dont know how to determine if the ball hit the block or the paddle (i have to treat them differently).
Second i dont know how to figure where the ball hit the object so i know how to bounce it off it properly (in the right direction).

Im using QGraphicsItems on a QGraphicsScene.

Thanks for your help

P.S. If it makes a difference i use Qt Jambi but it still looked like the right forum for this
