Detect Double Click on GUI button

Recommended Posts




I am trying to detect a gui button double click without using TimerInit or a global mouse hook.

Below is some code i have tried but cant understand why it is not working.


; *** Start added by AutoIt3Wrpper ***
#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
; *** End added by AutoIt3Wrapper ***

$hGUI = GUICreate("Test", 500, 500)
$Button = GUICtrlCreateButton("test", 10, 10, 400, 30)

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE

Func MY_WM_COMMAND($hWnd, $Msg, $wParam, $lParam)
    Local $nNotifyCode = BitShift($wParam, 16)
    Local $nID = BitAND($wParam, 0x0000FFFF)
    Local $hCtrl = $lParam
    If $nNotifyCode = $BN_DBLCLK And $nID = $Button Then
       ; do stuff
        Return 0

Now i know the GUI register has worked, My_WM_Command is receiving messages, $nID is getting the correct handle but $nNotifyCode is always the same?

Change this line:

$Button = GUICtrlCreateButton("test", 10, 10, 400, 30, BitOR($BS_NOTIFY, $GUI_SS_DEFAULT_BUTTON))

As stated by MSDN page on the page for notifications.


BN_DBLCLK notification code

Sent when the user double-clicks a button. This notification code is sent automatically for BS_USERBUTTON, BS_RADIOBUTTON, and BS_OWNERDRAW buttons. Other button types send BN_DBLCLK only if they have the BS_NOTIFY style.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.
