Okay I wrote a short script, the code you sent is missing the
connection, plus I don't know what "addPixmap" is, so here is a small
version of what I think you are trying to do.
If you aren't sublcassing the QGraphicsView, you can do the same thing I
am doing via the .scene() to get the QGraphicsScene
