22 * This header file contains the declarations of the %IScrollEventListenerF interface. @n
23 * If a change event is generated, a method of this interface is called. @n
24 * The applications that perform tasks related to the change events, call the methods of this interface.

42 * @interface IScrollEventListenerF
43 * @brief This interface implements a listener for scroll events.
47 * The %IScrollEventListenerF interface is the listener interface for receiving scroll events.
48 * The class that processes a scroll event implements this interface, and the instance created with that class is registered with
49 * a UI control, using the control's AddScrollEventListener() method. When the scroll event occurs, the OnScrollEndReached()
50 * method of that instance is invoked.
52 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/ui/implementing_panels.htm">Panels</a> and <a href="../org.tizen.native.appprogramming/html/guide/ui/implementing_listviews.htm">ListViews</a>.
