Adding items to a QGraphicsScene's selection list?

Can I manually add items to a QGraphicsScene's selection list?

QGraphicsItem::setSelected() or QGraphicsScene::setSelectionArea()

Hmm i tried set selected, but had some problems.

Basically I'm trying to do this, If I have two boxes connected by an arrow, and I select the two boxes, I also want it to automatically select the arrow.

I tried putting my code on itemchanged on my boxes, and it works when I ctrl select the two boxes, but not if I drag a rubberband. It seems like it gets selected momentairly but since the rubberband doesn't intersect the arrow, it gets immediately deselected.

What can I do?
