Problem getting selected item from listview...

11 posts in this topic

I was trying to figure how to get the text of the selected item of a listview.

So I came up with this, thinking it'd work:

_GUICtrlListView_GetItemText($hListView, _GUICtrlListView_GetSelectedIndices($hListView))

But it doesn't. What have I done wrong?

Valdersapien,

Have you looked at how the function returns the values? :D

If you set $fArray to True:

Array - With the following format

[0] - Number of Items in array (n)

[1] - First item index

[2] - Second item index

[n] - Last item index

If you set $fArray to False:

String - With the following format

"0|1|2|n"

M23

Oh! So GUICtrlListView_GetSelectedIndices() (with $fArray set to false) returns a string, not a number. I hadn't noticed this since I was using my listview with $LVS_SINGLECEL(or whatever it is)...

So instead of creating reading an array (another variable!), I just converted the string to an integer:

_GUICtrlListView_GetItemText($hListView, Int(_GUICtrlListView_GetSelectedIndices($hListView)))

And it works perfect now.

Thanks for pointing out that fact, I probably would have never noticed it!

EDIT: Now how do I tell when an item is clicked on? GUIGetMsg() doesn't seem to work...

And this way too:

#include <GuiListView.au3>
;some code here and etc.
    $si=_GUICtrlListView_GetSelectedIndices($List1)
    local $AA = _GUICtrlListView_GetItemText(GUICtrlGetHandle($List1),$si,0) ; is fisrt column data of cource selected. So if you retrive data only from second row replace it with 1

Look at the help file example for _GUICtrlListView_Create. It has many messages about list views including the one you need, $NM_CLICK.

Alright...managed to simplify that WM_NOTIFY function mentioned in the help file:

Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam)
    Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndListView
;~  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_CLICK ; Sent by a list-view control when the user clicks an item with the left mouse button
                    $tInfo = DllStructCreate($tagNMITEMACTIVATE, $ilParam)
                            ConsoleWrite('Clicked')

            EndSwitch
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc   ;==>WM_NOTIFY

It works perfect, but can it be simplified any further?

Not really. You could replace some of the variables to make the code shorter, but not simpler.

Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam)
    Local $hWndListView

    $hWndListView = $hListView
    If Not IsHWnd($hListView) Then $hWndListView = GUICtrlGetHandle($hListView)

    $tNMHDR = DllStructCreate($tagNMHDR, $ilParam)

    Switch HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
        Case $hWndListView
            Switch DllStructGetData($tNMHDR, "Code")
                Case $NM_CLICK ; Sent by a list-view control when the user clicks an item with the left mouse button
                    $tInfo = DllStructCreate($tagNMITEMACTIVATE, $ilParam)
                    ConsoleWrite('Clicked')
            EndSwitch
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc ;==>WM_NOTIFY

One simple way, if you only need single click

; Listview get selected row(s) - gw

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

Opt("MouseCoordMode", 2)
Global $iLvLeft = 10, $iLvTop = 10, $iLvWidth = 280, $iLvHeight = 180
Global $iWidth = 300, $iHeight = 230
$hGUI = GUICreate("Test", $iWidth, $iHeight)

$idListView = GUICtrlCreateListView("Items|SubItems", $iLvLeft, $iLvTop, $iLvWidth, $iLvHeight, $LVS_REPORT, $WS_EX_CLIENTEDGE)
$hListview = GUICtrlGetHandle($idListView)

_GUICtrlListView_SetExtendedListViewStyle($hListview, BitOR($LVS_EX_GRIDLINES, $LVS_EX_FULLROWSELECT))

For $i = 0 To 10
    _GUICtrlListView_AddItem($hListview, "Item" & $i)
    _GUICtrlListView_AddSubItem($hListview, $i, "SubItem" & $i, 1)
Next

$idSelected = GUICtrlCreateButton("Get Selected", 8, $iHeight - 30, $iWidth - 16, 20)

GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_PRIMARYDOWN
            If MouseGetPos(1) > ($iLvTop + 20) And MouseGetPos(1) < ($iLvHeight + $iLvTop) Then GetSelected()
        Case $idSelected
            GetSelected()
        Case $GUI_EVENT_CLOSE
            Exit

    EndSwitch
WEnd

Func GetSelected()
    ConsoleWrite(@LF)
    For $i = 0 To GUICtrlSendMsg($idListView, $LVM_GETITEMCOUNT, 0, 0)
        If GUICtrlSendMsg($idListView, $LVM_GETITEMSTATE, $i, 0x2) Then _
            ConsoleWrite("Selected Row: " & $i & " Text: " & _GUICtrlListView_GetItemText($hListview, $i) & " " & _GUICtrlListView_GetItemText($hListview, $i, 1) & @LF)
    Next
EndFunc
Otherwise handling wm_notify would be prefered.

@Picaxe - Thanks for the suggestion. I like your method, it's a fair bit simpler to work with..I can't really decide between the two, especially when it comes to having two listviews(what then?)

I made a small function to test if an item is selected. However it doesn't always work...

Func _GUICtrlListView_ItemSelected($hGUI, $hListview)
    $ListviewPos = ControlGetPos($hGUI, '', $hListview)
    $CursorInfo = GUIGetCursorInfo($hGUI)

    If GUIGetMsg() = $GUI_EVENT_PRIMARYDOWN And $CursorInfo[0] > $ListviewPos[0] And $CursorInfo[0] < ($ListviewPos[0] + $ListviewPos[2]) And _
    $CursorInfo[1] > $ListviewPos[1] And $CursorInfo[1] < ($ListviewPos[1] + $ListviewPos[3]) And _GUICtrlListView_GetSelectedIndices($hListview) <> ''  Then
        Return True
    Else
        Return False
    EndIf
EndFunc

I have a feeling it has to do with the GUIGetMsg() = $GUI_EVENT_PRIMARYDOWN bit...

I could have used $CursorInfo[2] to see if the mouse button was down but it wouldn't work...it just returned false all the time(anyone know why?)...
