Method Detail

getNativeGestureEvent

public NativeGestureEvent getNativeGestureEvent()

Returns the underlying native gesture event.

getRotation

public final double getRotation()

Returns the rotation induced by this event, in degrees, where clockwise rotation is represented by a positive value and counter-clockwise by a negative value.

getScale

public final double getScale()

Returns the scale change induced by this event. The value returned represents the distance between the two finger, as a fraction of the initial distance. This way, a value greater than 1.0 represents a zoom-in gesture, while a value smaller than 1.0, a zoom-out gesture.

sinkAllGestureEvents

public static void sinkAllGestureEvents(UIObject widget)

Sinks all gesture events for the specified UIObject.

unsinkAllGestureEvents

public static void unsinkAllGestureEvents(UIObject widget)

Stops sinking all gesture events for the specified UIO
