how to update/refresh a treeviewitem

3 posts in this topic

I am trying to update a treeviewitem, is it possible ?

Something like :

#include <GUIConstants.au3>

$gui = GuiCreate("treeviewtest", 450, 488, 490,360)

$tree = GUICtrlCreateTreeView(10, 60, 300, 360,-1 , $WS_EX_CLIENTEDGE)
$item = GUICtrlCreateTreeViewItem("original text", $tree)

$bt_test = GUICtrlCreateButton("test", 330,60,60,20)
GUISetState ()

while 1
    $msg = GUIGetMsg()
    if $msg = $GUI_EVENT_CLOSE Then  ExitLoop
    if $msg = $bt_test Then
        GUICtrlSetData("new text", $item)
        GUICtrlSetState($item,$GUI_SHOW)
    EndIf
WEnd
Exit

But the treeitem keeps his old text, any ideas ?

First you had the "GUICtrlSetData" wrong. (See code below and help file).

Second, I could only get it working with the beta. (I'm using the latest)

Will this help you on your way?

#include <GUIConstants.au3>

$gui = GuiCreate("treeviewtest", 450, 488, 490,360)

$tree = GUICtrlCreateTreeView(10, 60, 300, 360,-1 , $WS_EX_CLIENTEDGE)
$item = GUICtrlCreateTreeViewItem("original text", $tree)

$bt_test = GUICtrlCreateButton("test", 330,60,60,20)
GUISetState ()

while 1
    $msg = GUIGetMsg()
    if $msg = $GUI_EVENT_CLOSE Then  ExitLoop
    if $msg = $bt_test Then
        GUICtrlSetData($item, "new text")
        GUICtrlSetState($item,$GUI_SHOW)
    EndIf
WEnd
Exit
