Select multiple items in a qgraphicsscene with a selection rectangle
I have subclassed QGraphicsView and QGraphicsScene which has a huge amount of subclassed QGraphicsItem's in it. Now i want to select multiple item's, which works if i use the ctrl key+mouseclick. However, I want to be able to hold the mouse and draw a selection rectangle which selects the items.
Can Qt already do this or do I need to implement this on my own?
For the selection rectangle, have a look at the QRubberBand
Hope it helps
