As a user I want to be able to pan the map by holding the middle mouse button down and 'dragging'.
At this moment holding the ‘spacebar’ is used to pan.
Ok - I will couple back to the user that reported this. Is there a reason not to allow panning with the middle mouse button?
I didn’t mean you should not implement it. I just meant the ‘spacebar’ is already handleing this.
Perhaps you can look at its code to reuse parts for your middle mouse button implementation.
BTW. The ‘spacebar’ implementation is done in MapWinGIS, perhaps your middle mouse button implementation should also be coded in MapWinGIS?
