Trying to double-click ListView items...

[supersonic]

Hi!

I'm trying to create a function to select

each ListView item by double-click to start

an action...

There are many posts in this forum addressing

that kind of issue at least in some way...

I tested them without luck.

Is there anyone how could help me out?

Greets,

Hi supersonic,

could you please post some code that doesn't work? In my scripts I use the WM_NOTIFY approach without any problems.

Short working example:

expandcollapse popup

#include <GuiConstantsEx.au3>
#include <GuiListView.au3>
#include <GuiImageList.au3>
#include <WindowsConstants.au3>

Opt('MustDeclareVars', 1)

Global $hListView

_Main()

Func _Main()

    Local $GUI, $hImage
    $GUI = GUICreate("(UDF Created) ListView Create", 400, 300)

    $hListView = _GUICtrlListView_Create($GUI, "", 2, 2, 394, 268)
    _GUICtrlListView_SetExtendedListViewStyle($hListView, BitOR($LVS_EX_GRIDLINES, $LVS_EX_FULLROWSELECT, $LVS_EX_SUBITEMIMAGES))
    GUISetState()
    
    GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")

    ; Load images
    $hImage = _GUIImageList_Create()
    _GUIImageList_Add($hImage, _GUICtrlListView_CreateSolidBitMap($hListView, 0xFF0000, 16, 16))
    _GUIImageList_Add($hImage, _GUICtrlListView_CreateSolidBitMap($hListView, 0x00FF00, 16, 16))
    _GUIImageList_Add($hImage, _GUICtrlListView_CreateSolidBitMap($hListView, 0x0000FF, 16, 16))
    _GUICtrlListView_SetImageList($hListView, $hImage, 1)

    ; Add columns
    _GUICtrlListView_InsertColumn($hListView, 0, "Column 1", 100)
    _GUICtrlListView_InsertColumn($hListView, 1, "Column 2", 100)
    _GUICtrlListView_InsertColumn($hListView, 2, "Column 3", 100)

    ; Add items
    _GUICtrlListView_AddItem($hListView, "Row 1: Col 1", 0)
    _GUICtrlListView_AddSubItem($hListView, 0, "Row 1: Col 2", 1)
    _GUICtrlListView_AddSubItem($hListView, 0, "Row 1: Col 3", 2)
    _GUICtrlListView_AddItem($hListView, "Row 2: Col 1", 1)
    _GUICtrlListView_AddSubItem($hListView, 1, "Row 2: Col 2", 1)
    _GUICtrlListView_AddItem($hListView, "Row 3: Col 1", 2)

    ; Loop until user exits
    Do
    Until GUIGetMsg() = $GUI_EVENT_CLOSE
    GUIDelete()
EndFunc   ;==>_Main

Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam)
    #forceref $hWnd, $iMsg, $iwParam
    Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndListView, $tInfo
;~     Local $tBuffer
    $hWndListView = $hListView
    If Not IsHWnd($hListView) Then $hWndListView = GUICtrlGetHandle($hListView)

    $tNMHDR = DllStructCreate($tagNMHDR, $ilParam)
    $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    $iIDFrom = DllStructGetData($tNMHDR, "IDFrom")
    $iCode = DllStructGetData($tNMHDR, "Code")
    Switch $hWndFrom
        Case $hWndListView
            Switch $iCode
                Case $NM_DBLCLK ; Sent by a list-view control when the user double-clicks an item with the left mouse button
                    $tInfo = DllStructCreate($tagNMITEMACTIVATE, $ilParam)
                    MsgBox(0,"Doubleclick","Index " & DllStructGetData($tInfo, "Index") & @CRLF & "Subitem " & DllStructGetData($tInfo, "SubItem"))
            EndSwitch
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc   ;==>WM_NOTIFY

In this case unfortunately I don't have any code...

I know about WM_NOTIFY, but I don't unterstand to use it...

Hi supersonic,

Is this one of the sample code provided by AutoIt?

In this sample I could double-click a complete row.

But how to double-click a single item?

Yes, my example is a stripped down version of the example in _GUICtrlListView_Create. I altered my above example to output the doubleclicked Subitem as well.

Thank you! You really helped me out!

Now I'm trying to understand step by step how

this WM_NOTIFY-thing works... Once again, thank you!
