the long-tap detector</title><prolog><metadata><keywords/></metadata></prolog><conbody>
<p>To use the long-tap detector in your application, create an instance of
the class <codeph>CAknLongTapDetector</codeph>.</p>
<p>You must give the long-tap detector constructor a pointer to the owner;
otherwise the detector doesn’t know where to report long tap events. </p>
<p>You cannot set other long-tap detector parameters in the constructor. To
change these parameters, use the other methods in the API after the detector
is succesfully constructed. </p>
<p>You also need to pass any pointer events from the client side component
to the long-tap detector and enable pointer grab for the control’s window.</p>
<codeblock xml:space="preserve">void CMyContainer::ConstructL( const TRect&amp; aRect )
    {

    iLongTapDetector = CAknLongTapDetector::NewL( this );
    DrawableWindow()-&gt;SetPointerGrab( ETrue );

    }

void CMyContainer::HandlePointerEventL( const TPointerEvent&amp; aEvent )
    {

    iLongTapDetector-&gt;PointerEventL( aEvent );

    }
