Recommended Posts

Hello, here is the Help's example:

Select
            Case $msg = $listview
                MsgBox(0, "listview", "clicked=" & GUICtrlGetState($listview), 2)
        EndSelect

It workns only when I click on the top column. I'd like it to work when i click on each item inside the ListView, not just the title of a column. How to do it?

zwierzak,

You have to look for double-clicks on the ListView items as the ListView eats the single-clicks to show the selection.

You do it like this: ;)

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

; Set flag
$fDblClk = False

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

$hLV = GUICtrlCreateListView("Col 1", 10, 10, 200, 200)
$hLV_Handle = GUICtrlGetHandle(-1)

For $i = 1 To 20
    GUICtrlCreateListViewItem("Item " & $i, $hLV)
Next

GUISetState()

; Register "ListView DoubleClick" function
GUIRegisterMsg($WM_NOTIFY, "WM_ListView_DoubleClick")

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

    : if the ListView was clicked
    If $fDblClk = True Then
        ; Read the item
        $sText = GUICtrlRead($hLV)
        MsgBox(0, "", "You double-clicked the ListView on Item " & $sText)
        ; Reset the flag
        $fDblClk = False
    EndIf

WEnd

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

    #forceref $hWnd, $iMsg, $wParam
    Local $tNMHDR = DllStructCreate("int;int;int", $lParam)
    If @error Then Return
    ; Is it out ListView that has been clicked?
    If DllStructGetData($tNMHDR, 1) = $hLV_Handle Then
        ; Was it a double click?
        If DllStructGetData($tNMHDR, 3) = $NM_DBLCLK Then
            ; Set the flag
            $fDblClk = True
        EndIf
    EndIf
    $tNMHDR = 0
    Return $GUI_RUNDEFMSG

EndFunc   ;==>WM_ListView_DoubleClick

If you are not too familiar with GUIRegisterMsg, ther is a tutorial in the Wiki which you might find useful. :)

Exchange

Local $tNMHDR = DllStructCreate("int;int;int", $lParam)

with

Local $tNMHDR = DllStructCreate("INT_PTR;INT_PTR;INT", $lParam)

then it should work on x86 and x64...

KaFu,

We need a tutorial or something about these x86/x64 differences. I am getting very lost. ;)
