Just a short note on the flow-code structure. 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.

bye then
