_WinAPI_GetDlgCtrlID($hWnd) not work on TreeViewItem

[rexx]

I can get the CtrlID of treeview correctly, but for the treeviewitem it always return 0.

so it's not supported for treeview item?

Opt("GUIOnEventMode", 1)

$gui = GUICreate("", 220, 220)
GUISetOnEvent($GUI_EVENT_CLOSE, "Close")

$tv = GUICtrlCreateTreeView(10, 10, 200, 200)
$root = GUICtrlCreateTreeViewItem("root", $tv)
For $i = 0 To 3
    GUICtrlCreateTreeViewItem("Item" & $i, $root)
Next
GUICtrlSetState($root, $GUI_EXPAND)
GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")
GUISetState()

While 1
    Sleep(1000)
WEnd

Func Close()
    GUIDelete($gui)
    Exit

    Local $iTree = $tv

It is not supported for TreeViewItem - look here for why and how to get around it.
