60 * The Event Handler class is responsible for setting up receiving of Ecore events and then converts them
61 * to TouchEvents when it does receive them.
63 * These TouchEvents are then passed on to Core.

71 * @param[in] scene The scene where events will be sent to.
72 * @param[in] coreEventInterface Used to send events to Core.
73 * @param[in] gestureManager The Gesture Manager.
74 * @param[in] damageObserver The damage observer (to pass damage events to).
76 EventHandler( Dali::Integration::Scene scene, CoreEventInterface& coreEventInterface, GestureManager& gestureManager, DamageObserver& damageObserver );
84 * Feed (Send) touch event to core and gesture manager
85 * @param[in] touchEvent The touch event holding the touch point information.
