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);
