[Qt-interest] Moving viewport of QGraphicsView from cornerWidget

[Arvin Schnell]

Hi,

I would like to place a cornerWidget in a QGraphicsView that,
when pressed, shows a small window containing the demagnified
content of the QGraphicsScene. Moving the mouse should then move
the viewport of the QGraphicsView. Gimp has this nice feature.

Does anybody know of a Qt implementation for this?

It shouldn't be so difficult: The QGraphicsScene can be rendered
into a QPixmap. Anyway, I don't want to reimplementing the wheel.

Thanks,
  Arvin
