How can I use QGraphicsRectItem?

[jpn]

I will use convert QImage to QGraphicsRectItem. I have to implement paint() fromQGraphicsItem.

Why not QGraphicsPixmapItem?

But there is no virtual destructor in QGraphicsItem. how can I work out this?

Of course it's virtual as indicated by the docs.

Sorry, I made a mistake.

There is no virtual destructor in QGraphicsRectItem. So I can not inherit it. Could you please give some hints to solve this?

I will not use QGraphicsPixmapItem because QImage is used in my application.

It's declared as virtual by QGraphicsItem so it remains virtual in all subclasses.
