    14 <p>The class structure consists of the class <codeph>CaknLongTapDetector</codeph>.

    15 The <codeph>MaknLongTapDetectorCallBack</codeph> interface is used for notifying

    16 clients about long tap events.</p>

    21 <p>To receive long tap events in your application, implement the <codeph>MaknLongTapDetectorCallBack</codeph> interface.

    22 When the user makes long tap on the device screen, the framework sends events

    23 through this interface. Use the method <codeph>HandleLongTapEventL</codeph> to

    24 handle the events sent by the framework.</p>

    25 <p>You need to have a separate instance of this class for each client component

    26 using it to observe long taps in the component’s control area.</p>
