The reason it crashed was this: 1. Button was pressed => _panTimer started with the graphics view as destination. 2. Button was released => the graphicsview is destroyed 3. 300 ms later: Qt tries to deliver TimerEvent from _panTimer to the graphics view. Unfortunately, the graphics view is deleted, but Qt doesn't know that... (*crash*) We therefore chose to start the timer with a destination we are controlling the lifetime of: the QMacPanGestureRecognizer. Inside the timerEvent of that we can check if the actual target is already destroyed.
