33 * @brief A LongPressGesture is emitted when the user touches and holds the screen with the stated number of fingers.
35 * This gesture can be in one of two states, when the long-press gesture is first detected: Gesture::Started
36 * and when the long-press gesture ends: Gesture::Finished.
38 * Long press gesture finishes when all touches have been released.
