Class VOIEvent

java.lang.Object
java.util.EventObject
gov.nih.mipav.model.structures.event.VOIEvent
All Implemented Interfaces:
Serializable
public class VOIEvent extends EventObject
An event from a VOI. Registers the VOI as the event source and, if needed, the VOIBase that changed within the VOI.

It might be useful to have several different listeners VOI objects, to listen for different varieties of VOI changes, say, for curve-changing, or property-changing.

Perhaps in this case, the VOIListener could listen for all those, but most objects interested in the VOI, would only listen for particular changes in the VOI.
