How to get the last clicked position(x,y) when click on any screen

how to get the last clicked position(x,y) when click on any screen
I tried to give top_layer clickable and event_bubble flags, and add it event callback, when I click and the event just stoped at the top_layer, it cannot go through passing to the obj below it…

Is there an easy way to get the position of a click event in any screen?
Thanks!!
