The original SwingWorker class used not to be part of the Java distribution, but
a new version of it is now included in Java 6.0 (javax.swing.SwingWorker).
SwingWorker provides a number of communication and control
features:
- The
SwingWorker subclass can define a method, done(),
which is automatically invoked on the event dispatch thread when the
background task is finished.
SwingWorker implements java.util.concurrent.Future.
This interface allows the background task to provide a return value to the
other thread. Other methods in this interface allow cancellation of the
background task and discovering whether the background task has finished or
been cancelled.- The background task can provide intermediate results by invoking
SwingWorker.publish(),
causing SwingWorker.process() to be invoked from the event
dispatch thread.
- The background task can define bound properties. Changes to these
properties trigger events, causing event-handling methods to be invoked on
the event dispatch thread.
