With x11 get window at coordinates

Question

I want to get the top most window that is at position x and y. In Winapi I do this with WindowFromPoint seen here: https://msdn.microsoft.com/en-us/library/ms633558%28v=vs.85%29.aspx

Is there any equivalent in x11? I have covered the entire screen with a window and i want to know all the windows that are at the point in z order.

I think that's what Ill have to do, as XQueryPointer wont give me whats behind the current window. With XQueryTree I'll be able to detect which monitor its on too no? :) May you please move it to solution Ill accept it :) — yatg

XQueryTree gives list of window in the stacking order. You would need to query dimensions for every window in the list and stop when your point is within rectangle
