Run function when treeview item is clicked

[OmYcroN]

Hello. I have a treeview and items added with _GUICtrlTreeView_AddChild()

and their handles stored into an array. If I use the code below it will always run

the function but i want to use Function() only when clicking the item. I've used

$arrGuiMsg[2] <> 0x000000 but with no luck. So the problem is what happens when

an item is clicked in this situation ? How can i handle it ?

Global $arrGuiMsg
While True
    $arrGuiMsg = GUIGetMsg(1)
    Switch $arrGuiMsg[1]
        Case $window
            Switch $arrGuiMsg[0]
            EndSwitch
      
            Switch $arrGuiMsg[2]
                Case $arrItemHandles[0][0] To $arrItemHandles[Ubound($arrItemHandles) - 1][0]
                       If $arrGuiMsg[2] <> 0x000000 Then
                               Function()
                       Endif
            EndSwitch
    EndSwitch
WEnd

GUIGetMsg() works with control id's as used by the internal GUICtrl* functions. Look at the example for _GUICtrlTreeView_Create() for how to react to clicks

I've looked at WM_NOTIFY but I can't fint the correct case for checking/unchecking a checkbox. $NM_CLICK gets all clicks within the treeview. It there is other example on this matter please direct me. Thanks.
