20 * @brief This is the header file for the %IAdjustmentEventListener interface.
22 * This header file contains the declarations of the %IAdjustmentEventListener interface. @n
23 * If a change event is generated, a method of this interface is called. @n
24 * So, for tasks related to change events, use the methods of this interface.

38 * @interface IAdjustmentEventListener
39 * @brief This interface implements the listener for adjustment events.
43 * The %IAdjustmentEventListener interface is the listener interface for receiving adjustment events, which
44 * are fired when the knob of a Slider moves. The class that processes an adjustment event implements this interface, and the
45 * instance created with that class is registered with a UI control, using the control's AddAdjustmentEventListener() method.
46 * When the adjustment event occurs, the OnAdjustmentValueChanged() method of that instance is invoked.
48 * For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/ui/implementing_slider.htm">Slider</a>.

64 * Called when a change event occurs.
68 * @param[in] source The source of the event
