Class IltcZoomEvent

java.lang.Object

java.util.EventObject

ilog.tgo.composite.IltcZoomEvent

All Implemented Interfaces:

Serializable

public class IltcZoomEvent
extends EventObject

A zoom event is delivered when the logical zoom level of an IltcCompositeManager changes. This happens when an IltLogicalZoomPolicy is attached or detached, or when the transformer of the target view of an IltMixedZoomPolicy changes.

Note: For compatibility with JTGO 1.1, the event's source is the IlvManager, but many IltcCompositeManagers can use the same IlvManager, and each of them has its own zoom policy. Therefore the IltcZoomEvent mechanism is of limited use; an alternative is to make a subclass of IltZoomPolicy.

Since:

JTGO 1.0
