[jugador]

so have to use _WinAPI_InvalidateRect($h_GUI) or GUICtrlSetGraphic(.....,$GUI_GR_REFRESH)

Func Example()
..........
..........
..........
..........
GUISetState(@SW_SHOW)


While 1
    $Msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
                Exit

        Case $0A_MButton
        CreateChild()
        _WinAPI_InvalidateRect($h_GUI)
            
    EndSwitch
Wend
EndFunc

or

Func CreateChild()
Local $g_aidGraphics[7]
..........
..........
..........
..........
GUICtrlSetGraphic($g_aidGraphics[6], $GUI_GR_LINE, 60, 30) ; start point
GUICtrlSetGraphic($g_aidGraphics[6],$GUI_GR_REFRESH)
;;=============
EndFunc   ;==>CreateChild

 

[Nine]

add this line after child creation :

_WinAPI_RedrawWindow($h_GUI)
