Wysota,

Thanks for your reply. The QPixMap is embedded in a QGraphicsPixMapItem, and inserted in a QGraphicsScene. The final effect I have to have is to make it so when I hover over part of this QGraphicsPixMapItem, I can tell over which of the QGraphicsItems in the QGraphicsScene used to make the QGraphicsPixMap I am hovering.

(Basically it's a QGraphicsScene within a QGraphicsScene, but I am taking a QPixMap of the smaller scene.)

The final effect is you have a QPixMap on the scene, you double click it, it opens a window containing the contents of the QPixMap, you edit it, close it, and it recreates the QPixMap based on the scene in the opened window.

As I said, the problem now is hovering over part of the QPixMap, and identifying which part of the 'subscene' I am over. The scene does not still exist as a scene, as it is constructed and destroyed when it's window is opened and closed, and the pos coordinates are wrong, as described in my first post.
