Thanks for that solution, that does make sense. I will be using my method of setting the EventQueue of the window as that requires no changes to my picker and I can keep my code base between desktop and Android the same apart for the viewer code.
I suggest that for the examples we add the Code: viewer->getEventQueue()->setMouseInputRange(x, y, x + width, y + height); line to make the examples usable again.
