I have system that has classes derived from QGraphicsWidget. I manage derived class objects in layouts on QGraphicsScene. Now I need a compound item that contain two or more QGraphicsWidget in it and also I need to put that item inside my layout. So I choose QGraphicsItemGroup and write I class like this.
class CompositeItem : public QGraphicsItemGroup,public QGraphicsLayoutItem
{
...
};
I only implemented sizeHint function again. When add CompositeItem instance to layout it does not shown. What may cause this? Where I made wrong?
