I have the following problem. I have a whole window with 3 buttons. I want to cover them with a (invisible) skinnablepopupcontainer in order to know when the user touches out of the buttons. My problem is that i want to cut the skinnablepopupcontainer with the region of each of the buttons. This way I'll know when the user clicks out of the buttons, and I won't "block" the interaction with the buttons.
