_GUICtrlListView_MapIndexToID() does not work

[lee321987]

Hello.  Both of these don't work:

_GUICtrlListView_MapIDToIndex()

_GUICtrlListView_MapIndexToID()

#include <GuiListView.au3>

$Form1 = GUICreate('Form1', 220, 140, 180, 200)
$ListView1 = GUICtrlCreateListView('col1|col2', 10, 10, 200, 120)

GUISetState(@SW_SHOW)

$item_0 = GUICtrlCreateListViewItem('a|b', $ListView1)
$item_1 = GUICtrlCreateListViewItem('foo|bar', $ListView1)

ConsoleWrite('0 acutal ID: ' & $item_0 & @CRLF)
ConsoleWrite('1 actual ID: ' & $item_1 & @CRLF)

$iID = _GUICtrlListView_MapIndexToID($ListView1, 0)

ConsoleWrite('MapIndexToID: ' & $iID & @CRLF)
ConsoleWrite('MapIDToIndex: ' & _GUICtrlListView_MapIDToIndex($ListView1, $iID) & @CRLF)

; Using variable returned from control creation:
ConsoleWrite('MapIDToIndex using creation var: ' & _GUICtrlListView_MapIDToIndex($ListView1, $item_0) & @CRLF)

Exit

While 1
    Sleep(300)
WEnd

 

outputs:

0 acutal ID: 4
1 actual ID: 5
MapIndexToID: 0
MapIDToIndex: 0
MapIDToIndex using creation var: -1

If you read carefully help file, you should understand that the LV ID is not the same as the AutoIt GUI ID.  The listview ID is an internal ID to track uniqueness of an item (changes can happened after deletion/creation).

But you can get the actual AutoIt GUI ID, with _GUICtrlListView_GetItemParam when you create your LV items with GUICtrlCreateListViewItem (as AutoIt assigns its own ID to the data param of the listview)
