public class ZTransformEvent

extends java.awt.AWTEvent

ZTransformEvent is an event which indicates that a transform group has changed.

Transform events are provided for notification purposes ONLY; Jazz will automatically handle changes to the transform contents internally so that the program works properly regardless of whether the program is receiving these events or not.

This event is generated by a ZTransformGroup node when its transform is changed. The event is passed to every ZTransformListener or ZTransformAdapter object which registered to receive such events using the transform's addTransformListener method. (ZTransformAdapter objects implement the ZTransformListener interface.) Each such listener object gets this ZTransformEvent when the event occurs.

Field Summary

java.awt.geom.AffineTransform	transform The value of the transform before the transform was changed for transform events (or null for other event types).
static int	TRANSFORM_CHANGED This event indicates that the transform changed.
static int	TRANSFORM_FIRST The first number in the range of ids used for transform events.
static int	TRANSFORM_LAST The last number in the range of ids used for transform events.

Field Detail

TRANSFORM_FIRST

public static final int TRANSFORM_FIRST

The first number in the range of ids used for transform events.

TRANSFORM_LAST

public static final int TRANSFORM_LAST

The last number in the range of ids used for transform events.

TRANSFORM_CHANGED

public static final int TRANSFORM_CHANGED

This event indicates that the transform changed.

transform

public java.awt.geom.AffineTransform transform

The value of the transform before the transform was changed for transform events (or null for other event types).

Constructor Detail

ZTransformEvent

public ZTransformEvent(ZTransformGroup source,
                       int id,
                       java.awt.geom.AffineTransform transform)

Constructs a ZTransformEvent object.

Parameters:

source - the ZTransform object that originated the event

id - an integer indicating the type of event

transform - The original transform (for transform events)

Method Detail

getTransform

public ZTransformGroup getTransform()

Returns the originator of the event.

Returns:

the ZTransformGroup object that originated the event

getOrigTransform

public java.awt.geom.AffineTransform getOrigTransform()

For transform change events, this returns the value of the transform before the transform was changed.

Returns:

the original transform value.
