I am currently able to load my image into a grahpics scene, and then again into a QGraphicsViewer.

I am able to implement a zoom feature by dtecting a QEvent::Wheel and then calling the graphicsViews’s scale() function.

However, I can’t seem to figure out how to get the pan functionality working. I basically want to detect when a mouse has clicked down on the image, and then move the image left, right, up or down along with the mouse.

As of right now, I basically have a MouseFilter class that is detecting events, and doing different things depending on the event type. I attached that listener to the QGraphicsView object

    QGraphicsView has build-in mouse-panning support. Set correct DragMode and it will handle the rest. You do need the enable scroll bars for that to work.
