      • POSSIBLE

        public static final int POSSIBLE
        WorldWind.GestureState constant for the POSSIBLE gesture recognizer state. Gesture recognizers in this state are idle when there is no input event to evaluate, or are evaluating input events to determine whether or not to transition into another state.

        Constant Field Values

      • FAILED

        public static final int FAILED
        WorldWind.GestureState constant for the FAILED gesture recognizer state. Gesture recognizers transition to this state from the POSSIBLE state when the gesture cannot be recognized given the current input.

        Constant Field Values

      • RECOGNIZED

        public static final int RECOGNIZED
        WorldWind.GestureState constant for the RECOGNIZED gesture recognizer state. Discrete gesture recognizers transition to this state from the POSSIBLE state when the gesture is recognized.

      • BEGAN

        public static final int BEGAN
        WorldWind.GestureState constant for the BEGAN gesture recognizer state. Continuous gesture recognizers transition to this state from the POSSIBLE state when the gesture is first recognized.
        See Also:
        Constant Field Values

      • CHANGED

        public static final int CHANGED
        WorldWind.GestureState constant indicating the CHANGED gesture recognizer state. Continuous gesture recognizers transition to this state from the BEGAN state or the CHANGED state, whenever an input event indicates a change in the gesture.
        See Also:
        Constant Field Values

      • CANCELLED

        public static final int CANCELLED
        WorldWind.GestureState constant for the CANCELLED gesture recognizer state. Continuous gesture recognizers may transition to this state from the BEGAN state or the CHANGED state when the touch events are cancelled.
        See Also:
        Constant Field Values

      • ENDED

        public static final int ENDED
        WorldWind.GestureState constant indicating the ENDED gesture recognizer state. Continuous gesture recognizers transition to this state from either the BEGAN state or the CHANGED state when the current input no longer represents the gesture.
