The "container" Items (ForLoopItem and WhileLoopItem) must be derived from QGraphicsItem. We should sub-class QGraphicsItem and implement QGraphicsItem::dropEvent to handle dropping of flow-code elements. QGraphicItems can have children, which can be painted "inside" the parent Item. (All coordinates are relative to the parents coordinates.) Qt handles all this, we just need to implement the handler for the dropEvent. This is just a minor implementation issue, but it should be changed. A QGraphicsView can only have one QGraphicsScene at a time. And a Scene can't contain a Scene. (As I said, this is handled by the QGraphicsItems, which can have children and provide some sort of "nested" setup.
