Lock windows together?

[darkjohn20]

I've seen a program with a main GUI have a child window that moves along with the parent, and I was wondering how you can lock the child to the side of the parent.

For example, I have Window_One as the main window, and Window_Two needs to be locked to the right side of it.

OOOOTTTT

OOOOTTTT

OOOOTTTT

That's a rough "drawing".

I have this code:

While 1
    $WinPos = WinGetPos("Parent")
    $Child = WinMove("Child", "", $WinPos[0]+$WinPos[2]+10, $WinPos[1])
    Sleep(100)
WEnd

which moves the child correctly, but only AFTER I finish dragging the parent around. How can I make it follow the parent even WHILE I am dragging it?
