how to detect double-click on a list item?

[sigil]

I want to make a list, and let the user select an item from the list by double-clicking it. I've read the help file, and it seems like I need to use $LBS_NOTIFY when I declare my list, but I don't know how to detect the double-click, so that I can make the list window close once the user has selected the item. So far, I can detect a single-clicked value, but I want to make it more user-friendly by only executing the next code section if there's a double-click.

Here's my code:

#include <guiconstants.au3>

$null=""
dim $choices[4]=[1,2,3,4]

guicreate("My List")
$options=guictrlcreatelist($null,10,20,200,200,$lbs_notify)
for $c=0 to ubound($choices)-1
    $text=$choices[$c]
    guictrlsetdata($options,$text)
Next
guisetstate()
while 1
    $msg=guigetmsg()
    $selection=guictrlread($options)
    if ($msg=$gui_event_close) or ($msg=$options) Then
        ExitLoop
    EndIf
WEnd
msgbox(0,"",$selection)

Hi,

I don't sure about List, but maybe ListView?

#include <GuiConstants.au3>

Global Const $WM_NOTIFY = 0x004E
Global $DoubleClicked   = False

GUICreate("Double Click Demo", 400, 300)
GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")


$ListViewID = GuiCtrlCreateListView("List Column", 10, 20, 380, 250)

For $i = 1 To 10
    GuiCtrlCreateListViewItem("Item " & $i, $ListViewID)
Next

GUISetState()

While GUIGetMsg() <> -3
    Sleep(10)
    If $DoubleClicked Then
        DoubleClickFunc()
        $DoubleClicked = False
    EndIf
WEnd

Func DoubleClickFunc()
    MsgBox(64, "OK", "Double Clicked: " & GUICtrlRead(GUICtrlRead($ListViewID)))
EndFunc

Func WM_NOTIFY($hWnd, $MsgID, $wParam, $lParam)
    Local $tagNMHDR, $event, $hwndFrom, $code
    $tagNMHDR = DllStructCreate("int;int;int", $lParam)
    If @error Then Return 0
    $code = DllStructGetData($tagNMHDR, 3)
    If $wParam = $ListViewID And $code = -3 Then $DoubleClicked = True
    Return $GUI_RUNDEFMSG
EndFunc

Where can you find the constants, such as $LBN_DBLCLK?

Where can you find the constants, such as $LBN_DBLCLK?

In the beta you should be able to find the constants depending which control etc your looking for.

For example $LBN_DBLCLK should be found in ListBoxConstants.au3

I'm guessing that is what you mean, if you mean where do the values come from I used a tool call APIViewer 2004

Ok, thanks, I found them... however they were under #include <A3LListbox.au3> that PaulIA made and not in my beta. I'm downloading the newest beta now but it's going to take a few minutes.

EDIT: Beta fixed it. Now it the other constants I was using too
