[Qt-interest] Using a QRubberBand in a QGraphicsItem

[Mihail Naydenov]

As far as i understand, you want to mark portion of an Item.

This seems trivial - you either override its (Item's) Paint and draw a rect 
ontop, resizing on mouse events
or
have a RectItem as Item's child and resize it on mouse events.
