All Implemented Interfaces:
Serializable, Cloneable
public final class SwipeEvent
extends GestureEvent
Swipe event indicates that user performed a swipe gesture such as dragging a finger in one direction on touch screen.

Unlike some other gestures, the swipe gesture is not continual - the whole gesture produces only one event. The event is delivered to the top-most node picked on the gesture coordinates.

The swipe gesture has four types according to the movement direction. The gesture can be performed by any number of touch points, the number is provided by getTouchCount() method.

Note that swipe and scroll gestures are not exclusive. A single touch screen action can result in both gestures being delivered.

Note that the capability to produce swipes is dependent on the used input devices and underlying platform's capabilities and settings (especially without touch-screen user's possibilities of producing swipes are significantly reduced).

As all gestures, swipe can be direct (performed directly at the concrete coordinates as on touch screen - the center of the gesture is used as gesture coordinates) or indirect (performed indirectly as on track pad - the mouse cursor location is usually used as the gesture coordinates in this case).

      public SwipeEvent​(Object source, EventTarget target, EventType<SwipeEvent> eventType, double x, double y, double screenX, double screenY, boolean shiftDown, boolean controlDown, boolean altDown, boolean metaDown, boolean direct, int touchCount, PickResult pickResult)
      Constructs new SwipeEvent event.
      Parameters:
      source - the source of the event. Can be null.
      target - the target of the event. Can be null.
      eventType - The type of the event.
      x - The x with respect to the scene.
      y - The y with respect to the scene.
      screenX - The x coordinate relative to screen.
      screenY - The y coordinate relative to screen.
      shiftDown - true if shift modifier was pressed.
      controlDown - true if control modifier was pressed.
      altDown - true if alt modifier was pressed.
      metaDown - true if meta modifier was pressed.
      direct - true if the event was caused by direct input device. See GestureEvent.isDirect()
      touchCount - number of touch points
      pickResult - pick result. Can be null, in this case a 2D pick result without any further values is constructed based on the scene coordinates and the target
