Using Something Like the Composite Pattern

It would be better if there were a JMenuComponent interface that both the JMenuItem and the JMenu implemented (realizations of which could be added to a JMenu).

• Standard Types:
  • Message Dialog
  • Option Dialog
  • Input Dialog
  • File Dialog
  • Color Dialog
• Custom:
  • Use a modal window
  • Sometimes return information and sometimes require a callback
