The normal behavior of almost any GUI per click on one of the controllers is to call an Event for this control. If in one place there are several controls, the event is called only for the "top".
Tell me, please, is it possible to learn about all such "hits"? In my case, there is a Canvas with a bunch of child Ellipse'ov, which must respond to the click.
PS: I do not see any problems in order to calculate the intersection manually, but I would like to do without crutches :)
