How could I save Items on a QGraphicsScene?

[pinkfrog]

Hi,all

I'm working with QGraphicsView and I want to save all the items on the QGraphicsScene to a file which could be reload into the scene. Is there any function in Qt4 that I can use directly?
If not, what should I do?

Thanks for your help!
