Get selcected items in List View

[amf]

Hi all

I have a stange little problem... or actually two.

What I want to do is get the index of the selected item in a List View.

I wrote this code and when I try to get the index in function: Lst_ValuesClick()

and show it with: MsgBox(0, "$SelIndex: ", $SelIndex), the value of the index is shown

correct. When I use it in: MsgBox(0, "$SelItemTxt", _GUICtrlListView_GetItemText($Lst_Values, $SelIndex)),

the value is empty.

Another thing is that I want to have the selected value to the editbox by clicking on it in the List View,

but nothing happens when I click the values... only when I click on the Columnname.

Anyone have any ideas?

Here is the code...

expandcollapse popup

#include <ButtonConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <GUIListView.au3>
#include <WindowsConstants.au3>

Opt("GUIOnEventMode", 1)

$Frm_Main = GUICreate("Main", 202, 270, 193, 123)
GUISetOnEvent($GUI_EVENT_CLOSE, "Frm_MainClose")
$Lst_Values = GUICtrlCreateListView("Items", 16, 16, 169, 175)
GUICtrlSetOnEvent(-1, "Lst_ValuesClick")
$Inp_Value = GUICtrlCreateInput("", 16, 200, 169, 21)
$Btn_Add = GUICtrlCreateButton("Add to list", 16, 232, 75, 25, $WS_GROUP)
GUICtrlSetOnEvent(-1, "Btn_AddClick")
$Btn_Delete = GUICtrlCreateButton("Delete", 112, 232, 75, 25, $WS_GROUP)
GUICtrlSetOnEvent(-1, "Btn_DeleteClick")
GUISetState(@SW_SHOW)

While 1
    Sleep(100)
WEnd

Func Btn_AddClick()
    _GUICtrlListView_AddItem($Lst_Values, GUICtrlRead($Inp_Value))
EndFunc

Func Btn_DeleteClick()
    _GUICtrlListView_DeleteItemsSelected($Lst_Values) ;deleting selected item
EndFunc

Func Frm_MainClose()
    Exit
EndFunc

Func Lst_ValuesClick()
    $SelIndex =  _GUICtrlListView_GetSelectedIndices($Lst_Values))
    MsgBox(0, "$SelIndex: ", $SelIndex)
    MsgBox(0, "$SelItemTxt", _GUICtrlListView_GetItemText($Lst_Values, $SelIndex))
EndFunc

amf,

Answer 1: _GUICtrlListView_GetItemText is one of those UDF function that requires the handle of the control and not its ControlID.

Answer 2: Try using GUIRegisterMsg to react to clicks on the ListView. It is best to use double clicks, as you need single clicks to actually select the value.

Then you get something like this:

expandcollapse popup

#include <ButtonConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <GUIListView.au3>
#include <WindowsConstants.au3>

Global $fDblClk = False

Opt("GUIOnEventMode", 1)

$Frm_Main = GUICreate("Main", 202, 270, 193, 123)
GUISetOnEvent($GUI_EVENT_CLOSE, "Frm_MainClose")
$Lst_Values = GUICtrlCreateListView("Items", 16, 16, 169, 175)
$Lst_Handle = GUICtrlGetHandle(-1)
$Inp_Value = GUICtrlCreateInput("", 16, 200, 169, 21)
$Btn_Add = GUICtrlCreateButton("Add to list", 16, 232, 75, 25, $WS_GROUP)
GUICtrlSetOnEvent(-1, "Btn_AddClick")
$Btn_Delete = GUICtrlCreateButton("Delete", 112, 232, 75, 25, $WS_GROUP)
GUICtrlSetOnEvent(-1, "Btn_DeleteClick")
GUISetState(@SW_SHOW)

GUIRegisterMsg($WM_NOTIFY, "WM_ListView_DoubleClick")

While 1
    Sleep(10)

    If $fDblClk = True Then
        $fDblClk = False
        Lst_ValuesClick()
    EndIf

WEnd

Func Btn_AddClick()
    _GUICtrlListView_AddItem($Lst_Values, GUICtrlRead($Inp_Value))
EndFunc

Func Btn_DeleteClick()
    _GUICtrlListView_DeleteItemsSelected($Lst_Values) ;deleting selected item
EndFunc

Func Frm_MainClose()
    Exit
EndFunc

Func Lst_ValuesClick()
    $SelIndex =  _GUICtrlListView_GetSelectedIndices($Lst_Values)
    MsgBox(0, "$SelIndex: ", $SelIndex)
    MsgBox(0, "$SelItemTxt", _GUICtrlListView_GetItemText($Lst_Handle, $SelIndex))

EndFunc

; React to double clicks on recent ListView
Func WM_ListView_DoubleClick($hWnd, $iMsg, $wParam, $lParam)

    #forceref $hWnd, $iMsg, $wParam
    Local $tNMHDR = DllStructCreate("int;int;int", $lParam)
    If @error Then Return
    If DllStructGetData($tNMHDR, 1) = $Lst_Handle Then
        If DllStructGetData($tNMHDR, 3) = $NM_DBLCLK Then $fDblClk = True
    EndIf
    $tNMHDR = 0
    Return $GUI_RUNDEFMSG

EndFunc   ;==>WM_ListView_DoubleClick

I hope that helps.

Ahh... works like a charm

And a nice little function for the dblclk to.

Thanks
