Adds a given window as a child window of the window.
- macOS 10.2+
The child window to order.
child is added as a child of the window, it is maintained in relative position indicated by
place for subsequent ordering operations involving either window. While this attachment is active, moving
child will not cause the window to move (as in sliding a drawer in or out), but moving the window will cause
child to move.
Note that you should not create cycles between parent and child windows. For example, you should not add window B as child of window A, then add window A as a child of window B.
