[Solved] How to intercept double click on input control?

Recommended Posts

Normally, double-clicking on an input control highlights any existing contents. But I need to intercept the double click and perform a different action.

I've used methods for Listviews ... and the following will return an indicator for a label:

Func WM_COMMAND($hWnd, $MsgID, $wParam, $lParam)
    Local Const $STN_DBLCLK = 1
    Local $nID = BitAND($wParam, 0xFFFF)
    Local $nNotifyCode = BitShift($wParam, 16)
    If $nID = $label And $nNotifyCode = $STN_DBLCLK Then $DoubleClick = 1
    Return $GUI_RUNDEFMSG
EndFunc

But I haven't been able to detect the double click on an input control.

Any suggestions will be greatly appreciated.

Thanks in advance.

Thanks for that solution!

For anyone following this, I optimized it for multiple inputs by creating handles when the inputs were created:

Global $hEdit1 = GUICtrlGetHandle($edit1)
Global $hEdit2 = GUICtrlGetHandle($edit2)               ; create handles for every input
Global $hEdit3 = GUICtrlGetHandle($edit3)

I then turned the processing around in the associated function to be more efficient:

Func _WindowProc($hWnd, $Msg, $wParam, $lParam)
    Switch $Msg
        Case $WM_LBUTTONDBLCLK
            Switch $hWnd
                Case $hEdit1
                    $DoubleClick = $Edit1
                    Return 0
                Case $hEdit2
                    $DoubleClick = $Edit2
                    Return 0
:
:

The function returns the control ID that was double-clicked and everything works as I need.

I appreciate the help!

Here is an exemple of detecting double click in a listview too maybe it can help

Func WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)
         If $WMNotifyTest = 1 Then
         ConsoleWrite ("; WMNotify () Is Working!!"&@CRLF)
         $WMNotifyTest += 1
         EndIf
    #forceref $hWnd, $iMsg, $wParam
    Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndListView, $tInfo
    ; Local $tBuffer
    $hWndListView = $Console
    If Not IsHWnd($Console) Then $hWndListView = GUICtrlGetHandle($Console)

    $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    $iIDFrom = DllStructGetData($tNMHDR, "IDFrom")
    $iCode = DllStructGetData($tNMHDR, "Code")
    Switch $hWndFrom
        Case $hWndListView
            Switch $iCode
                Case $NM_CLICK ; Sent by a list-view control when the user clicks an item with the left mouse button
                    $tInfo = DllStructCreate($tagNMITEMACTIVATE, $lParam)
                    _DebugPrint("$NM_CLICK" & @CRLF & _
                            $TextFav = _GUICtrlListView_GetItemText($Console, DllStructGetData($tInfo, "Index")) & _

I've used methods for Listviews

Yes, I've been able to have doubleclicks work for Listviews by detecting $NM_DBLCLK ... but for a reason I'll never fathom, the OS only makes that flag apply to Listviews.

Thanks for your response.
