Slow reaction with GUIOnEventMode?

[Info]

Opt("GUIOnEventMode",1)

Global $iClicks

$gui = GUICreate("test")
$hlist = GUICtrlCreateListView("A|B",2,2, 300, 400)
GUISetOnEvent(-3, "_Close", $gui)
For $i = 1 To 20 Step 2
    GUICtrlCreateListViewItem($i & "|" & $i + 1,$hlist)
    GUICtrlSetOnEvent(-1, "_Click")
Next
GUISetState()

While 1
    Sleep(100)
WEnd

Func _Click()
    $iClicks += 1
    ToolTip($iClicks)
EndFunc

Func _Close()
    Exit
EndFunc

I'm trying to capture double clicks on a listview but GUICtrlSetOnEvent reacts too late?

Info,

GUICtrlSetOnEvent is not the way to go here - you need to use a message handler:

expandcollapse popup

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

Opt("GUIOnEventMode",1)

Global $iClicks

$gui = GUICreate("test")
GUISetOnEvent(-3, "_Close", $gui)

$hlist = GUICtrlCreateListView("A|B",2,2, 300, 400)
$hList_Handle = GUICtrlGetHandle(-1)
For $i = 1 To 20 Step 2
    GUICtrlCreateListViewItem($i & "|" & $i + 1,$hlist)
Next

GUISetState()

; Register message handler
GUIRegisterMsg($WM_NOTIFY, "WM_ListView_DoubleClick")

While 1
    Sleep(100)
WEnd

Func _Close()
    Exit
EndFunc

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

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

EndFunc   ;==>WM_ListView_DoubleClick

Please ask if anything is unclear.
