Sort items in a ListView

[Lupo73]

I have tried to read other topics about it, but I don't understand how do it. I have a listview with 3 columns (software, version, update) and n lines (one per application) and I need to sort its items (they are added with "_GUICtrlListView_AddItem" and for each item is set also a parameter).

Firstly I need to sort all items (keeping subitems synchronized) in alphabetical order of the first column items. Then I need also to allow to order items (always keeping subitems synchronized) clicking on column headers.

I have tried with "_GUICtrlListView_SimpleSort($hListView, $B_DESCENDING, 0)", but it cause some bugs: doesn't keep parameters synchronized with items and remove the ".0" from versions like "1.0", "2.0" of apps (I think because sorting version column, it convert strings in integer if are read as numbers).

Doing this search yielded this post that contains this code:

#include <GuiConstantsEx.au3>
#include <GuiListView.au3>
#include <GuiImageList.au3>

GUICreate("ListView Add SubItem", 400, 300)
$hListView = GUICtrlCreateListView("", 2, 2, 394, 268, -1, $LVS_EX_FULLROWSELECT)
GUISetState()


; Add columns
_GUICtrlListView_InsertColumn($hListView, 0, "Column 1", 100)
_GUICtrlListView_InsertColumn($hListView, 1, "Column 2", 100)

_GUICtrlListView_RegisterSortCallBack($hListView)

; Add items
_GUICtrlListView_AddItem($hListView, "a", 0, _GUICtrlListView_GetItemCount($hListView) + 9999)
_GUICtrlListView_AddSubItem($hListView, 0, "1", 1, 1)

_GUICtrlListView_AddItem($hListView, "b", 1, _GUICtrlListView_GetItemCount($hListView) + 9999)
_GUICtrlListView_AddSubItem($hListView, 1, "3", 1, 1)

_GUICtrlListView_AddItem($hListView, "c", 1, _GUICtrlListView_GetItemCount($hListView) + 9999)
_GUICtrlListView_AddSubItem($hListView, 2, "2", 1, 1)


ToolTip("NOT SORTED")
Sleep(2000)
_GUICtrlListView_SortItems($hListview, 1); sorts the entire listview based off the column with index 1 (the second one)
ToolTip("SORTED")

; Loop until user exits
Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE
GUIDelete()

Does that help?

Yes, it help me.. but it doesn't work fine. I saw that it sort only items with the same parameter. I create items with this code:

$item = _GUICtrlListView_AddItem($hListView, $file, -1, $param)

and the parameter is 0, 1 or 2 (depend on source directory).

In this screenshot you can see that it firstly makes group by parameter (shown in the last column) and then sort by name:
