mouseMoveEvent problem in QGraphicsView/QGraphicsScene

[Lendrick]

I'm having an issue with QGraphicsScene (on Linux) not catching mouse move events when the mouse button is pressed. Instead, it appears to be sending the event to the window manager and just dragging the entire window, instead of allowing the QGraphicsScene to process the event. I reimplemented the QGraphicsScene::event() function to print out the name of the event that happens to the console, and it doesn't even seem to be seeing it. It will catch the event where the mouse button is pressed, but then move events go to the window manager.

Any idea why this might happen?

Thanks,
Bart

Did you install an event filter?

No. Do I need to?

Try installing one on the scene and see if you can get the mouse move events.
