All Implemented Interfaces:

ActionListener, ImageObserver, MenuContainer, Serializable, EventListener, Accessible, RootPaneContainer, WindowConstants

public class WizardDialog
extends JDialog
implements ActionListener

A dialog that presents the user with a sequence of steps for completing a task. The dialog contains "Next" and "Previous" buttons, allowing the user to navigate through the task.

When the user backs up by one or more steps, the dialog keeps the completed steps so that they can be reused if the user doesn't change anything - this handles the cases where the user backs up a few steps just to review what has been completed.

But if the user changes some options in an earlier step, then the dialog may have to discard the later steps and have them repeated.

THIS CLASS IS NOT WORKING CORRECTLY YET.
