GUICtrlSetData ONLY insert ? Not clear old data ?

[Trong]

#include <GUIConstants.au3>

Global $EditBufSize = 281474976710656

$MainGUI = GUICreate("Test", 620, 300 )
$GUI_Log=GUICtrlCreateEdit ("", 20,20,600,200, BitOR($ES_NOHIDESEL,$ES_AUTOVSCROLL,$ES_READONLY, $WS_HSCROLL,$WS_VSCROLL, $ES_MULTILINE))

GUISetState ()
    GUICtrlSetData ($GUI_Log, "Hello" & @CRLF,1)
    GUICtrlSetData ($GUI_Log, "World" & @CRLF,1)
While 1
    $msg = GUIGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            Exit
    EndSelect
WEnd

Exit 

Why "Hello" not Delete ?

Thanks!

Solution:

_GUICtrlEdit_SetText()

 

This does the same thing: 

GUICtrlSetData ($GUI_Log, "World" & @CRLF)
