public class WaitingDialog
extends JDialog
implements ActionListener

This class represents a JDialog with a Generic progress bar. When the dialog appears (probably before a presumably longer task starts), a indeterminated progress bar appears. When the task is meant to be finished and the dialog is notified, the progress bar will stop at its maximum length and an "OK" button will be enabled to end the dialog.
