Here is the code..

So i basically use the viola jones method to detect faces, and return a ´rect´ of where the face which is given to this function.. This function somehow detect something.. But doesn't detect the face but rather the button of the screen..
The window moves though as I move, but not at the area i want i to focus on , my face..
