Class SafeProgressBarUpdaterThread

java.lang.Object
  com.pixelmed.display.SafeProgressBarUpdaterThread

All Implemented Interfaces:

Runnable

public class SafeProgressBarUpdaterThread
extends Object
implements Runnable

A class that implements Runnable so that it can be invoked by EventQueue.invokeLater().

This is needed, for example, to call from a worker thread, since the progress bar methods used MUST be invoked on the AWT Event Dispatch Thread.

So, for example, instead of directly accessing the JProgressBar methods:

        progressBar.setMaximum(maximum);
        progressBar.setValue(value);
        progressBar.repaint();
 

do the following instead:

  progressBarUpdater = new SafeProgressBarUpdaterThread(progressBar);
  ...
        progressBarUpdater.setMaximum(maximum);
        progressBarUpdater.setValue(value);
        java.awt.EventQueue.invokeLater(progressBarUpdater);
