Why does ControlMove() does not work properly on hidden overlapped window ?

[SharpDressedMan]

Hi all,

I need to use ControlMove() on some controls of a hidden GUI window.

This works properly on a GUI window created with default style, but does not work on a GUI window created with style $WS_OVERLAPPEDWINDOW

func GUItest($bOverlapped)
    $m = GUICreate("test", 200, 100, -1, -1, $bOverlapped ? $WS_OVERLAPPEDWINDOW : -1)
    $g = GUICtrlCreateButton("test", 0, 0)
    ControlMove($m, "", $g, 30, 30)
    GUISetState()
endfunc

GuiTest(false)  ; button 'test' properly moved to (30,30)
GuiTest(true)   ; button 'test' not moved and still sitting at (0,0)

Any reason for this unexpected behavior ?

Any workaround to fix this ?

Thanks for any help

OK, after some searches in bug reports... I can answer my own question :

For moving GUI controls, GUICtrlSetPos() should be used instead of ControlMove()

Using this function, the control is moved properly whatever window style.

Bug fixed.
