Double Click select item in Listviewitem

[JohnRichard]

Hi all. I wanted to select item in listviewitem. what i have currently is to click item in listview then perform action when i click on selected item. What i wanted is to double click it instead of single click the item. i am using the $GUI_EVENT_PRIMARYDOWN to perform the action. Is there any way to double click the item then it will perform the desired function?

here is the sample code.

appreciate any suggestions and ideas. thanks.

#include <GuiConstants.au3>
#include <GuiListView.au3>

Opt('MustDeclareVars', 1)
Dim $listview, $Btn_Get, $Btn_GetSelected, $Btn_Exit, $msg, $Status, $a_Item, $i, $input
GUICreate("ListView Get Item Text Array", 392, 322)

$listview = GUICtrlCreateListView("col1|col2|col3", 40, 30, 310, 149)
GUICtrlCreateListViewItem("line1|data1|more1", $listview)
GUICtrlCreateListViewItem("line2|data2|more2", $listview)
GUICtrlCreateListViewItem("line3|data3|more3", $listview)
GUICtrlCreateListViewItem("line4|data4|more4", $listview)
GUICtrlCreateListViewItem("line5|data5|more5", $listview)
$Btn_Exit = GUICtrlCreateButton("Exit", 300, 260, 70, 30)
$Status = GUICtrlCreateInput("", 50, 200, 40, 20)
$input = GUICtrlCreateInput("", 50, 230, 40, 20)

GUISetState()
While 1
    $msg = GUIGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE Or $msg = $Btn_Exit
            ExitLoop
        Case $msg = $GUI_EVENT_PRIMARYDOWN
            $a_Item = _GUICtrlListView_GetItemTextArray($listview)
            If IsArray($a_Item) Then
                MsgBox(0, "", $a_Item)
                GUICtrlSetData($Status, "")
                GUICtrlSetData($Status, $a_Item[1])
                GUICtrlSetData($input, $a_Item[2])
            Else
                GUICtrlSetData($input, "")
            EndIf
    EndSelect
WEnd
Exit

I use the following method:

GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")

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 = $ListView And $code = -3 And _GUICtrlListView_GetSelectedCount($ListView) > 0 Then ;Put code here to deal with the double click
    Return $GUI_RUNDEFMSG
EndFunc

thanks Marlo. I'll try this.

JohnRichard,

I use a slightly different method. I set a flag when the double click is detected and then run code from within the While...WEnd loop. That way you return from the GUIRegisterMsg function ASAP - as recommended by the Help file: "the return to the system should be as fast as possible !!!".

So it looks something like this when put into a script:

; Register "Click on ListView function"
GUIRegisterMsg($WM_NOTIFY, "MY_WM_NOTIFY")

While 1

; Normal GUIGetMsg() code

; Check if mouse has doubleclicked
    If $fDblClk = True Then
        $fDblClk = False
        ExitLoop    ; You could also put the doubleclicked list code here if you prefer
    EndIf
    
Wend

; Deregister "Click on ListView function"
GUIRegisterMsg($WM_NOTIFY, "")

; Code for doubleclicked list follows here

; -----------

Func MY_WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)
    
    Local $tNMHDR = DllStructCreate("int;int;int", $lParam)
    If @error Then Return
    If DllStructGetData($tNMHDR, 3) = $NM_DBLCLK Then $fDblClk = True
    $tNMHDR = 0
        
EndFunc

I have found this to work well in a number of scripts.
