Hi all,

as suggested by others on the forum, I tried using timerEvent for my traffic simulation system. I looked at the mouse example and added a timerEvent for each of the vehicle in the simulation. The system seems slow though when I have more than 50 vehicles moving around. Is that generally a bad idea to have the timerEvent for each moving object? I have a scene class that contains all the vehicles (not a subclass of QGraphicsScene, just a normal class). Would it be better to have the scene class to response to timerEvent and update all vehicles at once?

Hope someone can advice on this. Thanks.
