List View Context Menu

[dantay9]

I have a list view with items in it. I have found this script and a few others that can set a context menu to show if an item in that list view is clicked. How can I find out what button on the context menu is clicked, if any?

I've had zero luck with performing any sort of complex function called from within a MW_NOTIFY or WM_COMMAND message trap.

Setting a simple flag inside the function, then using the flag to execute the goodies (like TrackPopupMenu) outside of WM_NOTIFY may behave better for you.

My two cents...

I am open to any ways, not to just the ones inside the WM_NOTIFY function. I don't exactly know what you mean, though. Do you have an example?

Nobody knows? Is it not possible?

You have buttons on your context menu?

You don't get replies to your question(s) if your question(s) don't make much sense and you fail to supply a reproducer script.

You can't expect others that may know how to do it, or may have enough knowledge to do it, to write the initial coding themselves on a free support forum.

Okay. I have a script which uses a listbox control. That listbox has lines of text in it that can be selected. I have solved the problem of finding out when a user is clicking on the list box and when they are clicking on the blank space. When the user clicks on one of the lines of text, and only on the text, I would like a context menu to appear so the user is able to delete the item. I can make the context menu appear, but I am not sure how to record if the delete menu was pressed or not. Here is what I have at the moment.

Func WM_NOTIFY($hWnd, $Msg, $wParam, $lParam)
    Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndListView1
    $hWndListView1 = $List1
    $hWndListView2 = $List2
    If Not IsHWnd($List1) Then $hWndListView1 = GUICtrlGetHandle($List1)
    If Not IsHWnd($List2) Then $hWndListView2 = GUICtrlGetHandle($List2)

    $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    $iIDFrom = DllStructGetData($tNMHDR, "IDFrom")
    $iCode = DllStructGetData($tNMHDR, "Code")

    Switch $hWndFrom
        Case $hWndListView1
            Switch $iCode
                Case $NM_RCLICK; Sent by a list-view control when the user clicks an item with the right mouse button
                    $tInfo = DllStructCreate($tagNMITEMACTIVATE, $lParam)
                    $Index = DllStructGetData($tInfo, "Index")
    EndSwitch

    Return $GUI_RUNDEFMSG
EndFunc  ;==>WM_NOTIFY
