40 * @brief This interface is used as the argument to the touch event listener.
44 * The %ITouchEventListener interface is the listener interface for receiving touch events.
45 * The class that processes a touch event implements this interface, and the instance created with that class is registered with a
46 * UI control, using the Control::AddTouchEventListener() method. When the touch event occurs, a method of that instance is
