2. the absolute coordinates of the pointer events are: (dx + px), (dy + py)
aka x_root and y_root in the ButtonEvent, if this saves you anything.
Sure it does, and it makes the code clearer (which is not bad too)!
3. the distance of the pointer event from the decorated window's origin (wx,wy) is: (dx + px) - wx, (dy + py) -wy
I'd call this "offset", because "distance" is the length of the vector from (x_root,y_root) to (wx,wy). :)
Luckily I'm writing this in Haskell, and so no risk of terminology confusion whatsoever. :) Thank you very much. It was really worth waiting. Cheers Andrea
