AutoIT TreeView get Current and Old Selection

[Renderer]

Hello Guys! I have a question regarding TreeView selections. How can I get the OLD and CURRENT selected Items in a TreeView? The script bellow does only get the current TreeView selected Item. 

global $hWin = GUICreate("TreeView --> ListView", 650,550)
global $TreeView = GUICtrlCreateTreeView(0,0,250,550)

;TreeView Items

global $tv_item_1 = GUICtrlCreateTreeViewItem("Item 1", $TreeView)
global $tv_item_2 = GUICtrlCreateTreeViewItem("Item 2", $TreeView)
global $tv_item_3 = GUICtrlCreateTreeViewItem("Item 3", $TreeView)

GUISetState()

global $current_selection
global $old_selection

While 1
   Switch GUIGetMsg()
   case -3

      ExitLoop

   EndSwitch

   local $tv_selection = _GUICtrlTreeView_GetSelection($TreeView); Gets the current TreeView Selection
   Consolewrite("Current Selection: " & $tv_selection & @crlf)
  

WEnd

Thanks in advance

Hello, 

I already shared multiple time this register msg. 

I think it can fit to your needs until you understand the GUIRegisterMsg()

Of course, you have to rework on variables.

GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")

Global $WMNotifyTest = 1

Func WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)

Or just modifying your code a bit :

#include <GuiTreeView.au3>

Global $hWin = GUICreate("TreeView --> ListView", 650, 550)
Global $TreeView = GUICtrlCreateTreeView(0, 0, 250, 550)

;TreeView Items

Global $tv_item_1 = GUICtrlCreateTreeViewItem("Item 1", $TreeView)
Global $tv_item_2 = GUICtrlCreateTreeViewItem("Item 2", $TreeView)
Global $tv_item_3 = GUICtrlCreateTreeViewItem("Item 3", $TreeView)

GUISetState()

Global $current_selection = 0, $tv_selection, $old_selection

SetSelection ()

While 1
  Switch GUIGetMsg()
    Case -3
      ExitLoop
    Case $tv_item_1 To $tv_item_3
      SetSelection()
  EndSwitch
WEnd

Func SetSelection ()
  $tv_selection = _GUICtrlTreeView_GetSelection($TreeView)
  If $current_selection <> $tv_selection Then
    $old_selection = $current_selection
    $current_selection = $tv_selection
    ConsoleWrite("Current Selection: " & $tv_selection & "  Old Selection = " & $old_selection & @CRLF)
  EndIf
EndFunc

This way you won't overload the CPU by always searching for the new selection...
