org.jdesktop.swingworker.SwingPropertyChangeSupport

All Implemented Interfaces:

java.io.Serializable

public final class SwingPropertyChangeSupport
extends java.beans.PropertyChangeSupport

This subclass of java.beans.PropertyChangeSupport is almost identical in functionality. The only difference is if constructed with SwingPropertyChangeSupport(sourceBean, true) it ensures listeners are only ever notified on the Event Dispatch Thread.
