This ProgressMonitor is normally invoked in roughly this form: <pre> InputStream in = new BufferedInputStream( new ProgressMonitorInputStream( parentComponent, "Reading " + fileName, new FileInputStream(fileName))); </pre><p> This creates a progress monitor to monitor the progress of reading the input stream. If it's taking a while, a ProgressDialog will be popped up to inform the user. If the user hits the Cancel button an InterruptedIOException will be thrown on the next read. All the right cleanup is done when the stream is closed. <p> For further documentation and examples see <a href="http://java.sun.com/docs/books/tutorial/uiswing/components/progress.html">How to
