Introduction
They say that necessity is the mother of invention. I needed a way of calculating the coordinates of a pop-up window so that it would be centered relative to the parent window. I checked the forum and the documentation but couldn't find anything like it so I created a simple function to do it for me.


The Code

Source: PopupXY.ahk
Documentation: PopupXY.html
Examples: PopupXY - Examples Of Use.ahk

Final Thoughts
I named the function PopupXY for lack of better name. If you can think of a better name, let me know.

I hope that someone finds this useful.
