Hallo Anthony,
Simple Touch Handler is limited to have 4 corners. Its shape, however, is not necessarily a rectangle. You can form it as desired to cover as good as possible the corresponding area. Also possible, use two or even three Simple Touch Handler to cover a complex shape. Then connect all Touch Handler to the same slot methods. For example:
In the above screenshot please note, how the implementation of a slot method associated to several Touch Handlers does access the correct handler by using the value sender. Via the value sender , the Touch Handler provides a reference to itself. In this way the slot method can access the sending Touch Handler and e.g, evaluate its variable CurrentPos.
I hope it helps you further.
Best regards
Paul Banach
