Identify multiple treeviews

Recommended Posts

Hi all !!

i am using a gui which contains 2 treeviews. How can i identify the treeview handle or controlID (or the treeview item) when i am clicking on a treeview item.

With only one treeview everything works fine. I used for example the GUICtrlRead($treeview1,1) to read the item text clicked on. But with 2 treeviews i dont know from which of both an item is selected.

I also tried $msg = GuiGetMsg(1) and then $msg[2] to get the needed information. But this dont seems to work ?!?

Maybe anyone has a solution or idea for this...

Welcome to the AutoIt forum. ;)

You need to intercept the click message and see which control issued it - like this:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiTreeView.au3>

; Set a flag to show which TreeView was clicked
Global $fTV = 0

$hGUI = GUICreate("Test", 500, 500)

$hTV_1 = GUICtrlCreateTreeView(10, 10, 200, 200)
$hWndTV_1 = GUICtrlGetHandle(-1)
For $i = 1 To 5
    GUICtrlCreateTreeViewItem("Item 1" & $i, $hTV_1)

$hTV_2 = GUICtrlCreateTreeView(260, 10, 200, 200)
$hWndTV_2 = GUICtrlGetHandle(-1)
For $i = 1 To 5
    GUICtrlCreateTreeViewItem("Item 2" & $i, $hTV_2)


; Intercept click messages

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE

    ; Is the flag set?
    If $fTV <> 0 Then
        ; Announce it
        MsgBox(0, "Click!", "You clicked in TreeView " & $fTV)
        ; Clear flag
        $fTV = 0


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

    #forceref $hWnd, $iMsg, $wParam
    Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndTreeview

    $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    $iCode = DllStructGetData($tNMHDR, "Code")
    ; Has a click occured?
    Switch $iCode
        Case $NM_CLICK
            ; Which TreeView
            Switch $hWndFrom
                Case $hWndTV_1
                    ; It was TV_1
                    $fTV = 1
                Case $hWndTV_2
                    ; It was TV_2
                    $fTV = 2
EndFunc   ;==>WM_NOTIFY

If you are not too sure about using GUIRegisterMsg, could I recommend this tutorial in the Wiki? ;)

Please ask if you have any questions. :)
