21 * @brief This is the header file for the %IGroupedListViewItemProviderF interface.
23 * This header file contains the declarations of the %IGroupedListViewItemProviderF interface. @n
24 * If an event is generated, a method of this interface is called. @n
25 * Therefore, if an application performs jobs related to the item events, it uses the methods of this interface.

38 * @interface IGroupedListViewItemProviderF
39 * @brief This interface implements the provider for the events generated by the GroupedListView control.
43 * The %IGroupedListViewItemProviderF interface is the interface for handling GroupedListView items.
44 * The class that handles list items implements this interface, and the instance created using the GroupedListView::Construct() method.
46 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/ui/implementing_listviews.htm">ListViews</a>.
48 class _OSP_EXPORT_ IGroupedListViewItemProviderF
53 * This polymorphic destructor should be overridden if required.
54 * This way, the destructors of the derived classes are called
55 * when the destructor of this interface is called.
