Hi,

thanks for your answer.

So, you don't tell me new things

My problem: I'm still a newbie with QT and I have very big problems to reimplement the drawBackground-Methode because I don't know the parameters of this method. For example: Which QPainter is needed to reimplement that method. I think I cannot use any Instance of a QPainter, I can?

Is there a special QPainter für the QGraphicsView?

My programm is almost finished, this is my last problem and I have no idea how I can solve this. Can you give me more explanation to reimplement this methode or can tell me an easier way to solve my problem, please?

Thanks!
