Control position (X/Y) in QM dialog

[r0n]

Sorry for this really stupid question but I can't figure this out.
I am trying to position the mouse pointer to the topleft corner of an inputfield after the dialog has been rendered.

If I remove "hDlg" from below, then it works spot on. But if I add it to enforce from dialog area it does not work.
I tried to get titlebar-height and add to 'y' but still isn't correct.

Code:

GetWinXY id(3 hDlg) x y cx cy hDlg
mou x y hDlg

(using latest version of windows 10)

Function control_position_test

Code:

str dd=

;END DIALOG
;DIALOG EDITOR: "" 0x2040601 "*" "" "" ""

str controls = "3"
str e3
if(!ShowDialog(dd &sub.DlgProc &controls)) ret
