Class JProgressWindow

  • All Implemented Interfaces:

    public class JProgressWindow
    extends Object
    implements ProgressListener
    Reports progress of a lengthly operation in a window. This implementation can also format warnings. Its method can be invoked from any thread (it doesn't need to be the Swing thread), which make it easier to use it from some background thread. Such background thread should have a low priority in order to avoid delaying Swing repaint events.
