Moderators Melba23 Posted December 17, 2011 Moderators Share Posted December 17, 2011 bingobin,Welcome to the AutoIt forum. You need to look for the $TVN_ITEMEXPANDEDW message like this:expandcollapse popup#include <GUIConstantsEx.au3> #include <WindowsConstants.au3> $hGUI = GUICreate("Test", 500, 500) $hTreeView = GUICtrlCreateTreeView(10, 10, 200, 200) $hRoot = GUICtrlCreateTreeViewItem("Root", $hTreeView) For $i = 1 To 10 GUICtrlCreateTreeViewItem("Item " & $i, $hRoot) Next GUISetState() GUIRegisterMsg($WM_NOTIFY, "_WM_NOTIFY") While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE Exit EndSwitch WEnd Func _WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam) #forceref $hWnd, $iMsg, $wParam Local $tStruct = DllStructCreate("hwnd hWndFrom;uint_ptr IDFrom;int Code", $lParam) Switch DllStructGetData($tStruct, "Code") Case -455 ; $TVN_ITEMEXPANDEDW ConsoleWrite("TreeView Expanded/Contracted" & @CRLF) EndSwitch EndFuncLook in the lower SciTE panel to see the mesage each time you click on the [+].If you want to know more about Windows messages and how to intercept them with GUIRegisterMsg, I recommend the GUIRegisterMsg tutorial in the Wiki.
