public class RotateEvent
extends GestureEvent

Rotate event indicates that user performed rotating gesture such as dragging two fingers around each other on track pad, touch screen or other similar device.

The event is delivered to the top-most node picked on the gesture coordinates in time of the gesture start - the whole gesture is delivered to the same node even if the coordinates change during the gesture.

The event provides two values: angle is the rotation angle of this event, totalAngle is the rotation angle of the whole gesture. Both values are in degrees and work well when added to the node's rotate property value (positive values for clockwise rotation).

As all gestures, rotation can be direct (performed directly at the concrete coordinates as on touch screen - the center point among all the touches is usually used as the gesture coordinates) or indirect (performed indirectly as on track pad - the mouse cursor location is usually used as the gesture coordinates).

The gesture's ROTATE events are surounded by ROTATION_STARTED and ROTATION_FINISHED events. If rotation inertia is active on the given platform, some ROTATE events with isInertia() returning true can come after ROTATION_FINISHED.

Field Detail

ANY

public static final EventType<RotateEvent> ANY

Common supertype for all rotate event types.

ROTATE

public static final EventType<RotateEvent> ROTATE

This event occurs when user performs a rotating gesture such as dragging two fingers around each other.

ROTATION_STARTED

public static final EventType<RotateEvent> ROTATION_STARTED

This event occurs when a rotating gesture is detected.

ROTATION_FINISHED

public static final EventType<RotateEvent> ROTATION_FINISHED

This event occurs when a rotating gesture ends.

Method Detail

getAngle

public double getAngle()

Returns:

The rotation angle of this event

getTotalAngle

public double getTotalAngle()

Gets the cumulative rotation angle of this gesture. The angle is in degrees and work well when added to the node's rotate property value (positive values for clockwise rotation).

Returns:

The cumulative rotation angle of this gesture

toString

public java.lang.String toString()

Returns a string representation of this RotateEvent object.

Overrides:

toString in class GestureEvent

Returns:

a string representation of this RotateEvent object.
