public class RotateEvent extends GestureEvent
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
.
