Hello.
Drag option works only on parent window but as we can see on the parent gui is showed up child gui (on the right side with the color).
Desired action is when we want to drag whole program we can also drag child gui and child gui will drag with parent gui.
How to do this?
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <Array.au3>
GUIRegisterMsg($WM_NCHITTEST, "_NCHITTEST")
$hGUI = GUICreate("Test", 500, 500, -1, -1)
$cButton_0 = GUICtrlCreateButton("Child 0", 10, 10, 80, 30)
$cB
