35 * @class ITouchPinchGestureEventListener
36 * @brief This interface implements the listener for the touch pinch gesture events.
40 * The %ITouchPinchGestureEventListener interface is the listener interface for receiving pinch gesture events.
41 * The class that processes a pinch gesture event implements this interface, and the instance created with that class is registered with a
42 * pinch gesture detector, using the TouchPinchGestureDetector::AddPinchGestureEventListener() method. When the pinch gesture event occurs, a method of that instance is
46 class _OSP_EXPORT_ ITouchPinchGestureEventListener
47 : virtual public ITouchGestureEventListener
52 * This polymorphic destructor should be overridden if required. This way, the destructors of the derived classes are called when the destructor of this interface is called.
56 virtual ~ITouchPinchGestureEventListener(void) {}
59 * Called when a pinch gesture detection is started.
63 * @param[in] gestureDetector The pinch gesture detector instance
65 virtual void OnPinchGestureStarted(Tizen::Ui::TouchPinchGestureDetector& gestureDetector) = 0;
68 * Called when a pinch gesture is detected and is in progress.
72 * @param[in] gestureDetector The pinch gesture detector instance
74 virtual void OnPinchGestureChanged(Tizen::Ui::TouchPinchGestureDetector& gestureDetector) = 0;
77 * Called when a pinch gesture detection is finished.
81 * @param[in] gestureDetector The pinch gesture detector instance
83 virtual void OnPinchGestureFinished(Tizen::Ui::TouchPinchGestureDetector& gestureDetector) = 0;
86 * Called when a pinch gesture detection is canceled.
90 * @param[in] gestureDetector The pinch gesture detector instance
92 virtual void OnPinchGestureCanceled(Tizen::Ui::TouchPinchGestureDetector& gestureDetector) = 0;
