+ * A dialog window that shows the progress of a long-running task.

+ * Before using this dialog, a {@code SwingWorker} task class has to be implemented

+ * Either the {@code doInBackground()} or {@code process(...)} method of the {@code Task}
+ * has to call {@code progressDialog.setValue(val)} to update the progress bar accordingly.
+ * </p>
+ * <p>
+ * Once the task and progress dialog are instantiated, it is necessary to attach listener that reacts to 
+ * the end of the task computation, e.g.,
+ * <pre>
+ * ProgressDialog progressDialog = new ProgressDialog(null);
+ * Task task = new Task(progressDialog);
+ *        
+ * task.addPropertyChangeListener((PropertyChangeEvent evt) -> {
+ *    if ("state".equals(evt.getPropertyName()) && (SwingWorker.StateValue.DONE.equals(evt.getNewValue()))) {
+ *        // code invoked when the task is done
+ *    }
+ * });
+ * </pre>
+ * Other states than the task end can be handled in similar way.
+ * </p>
