Summary of Chapter 6

• An application level main menu, and its associated pull-down menus have the major advantage of user familiarity.
  
  
• The MenuComponet hierarchy is a sibling of the Component hierarchy and supplies the facilities to implement menus.
  
  
• Only a Frame instance can contain a MenuBar which means that only independent top-level Windows, and so not Applets, can use a standard pull-down menu interface.
  
  
• Dialogs cannot exist independently of a top level Window and can be posted in a modal or non-modal manner.
  
  
• WindowEvents can be intercepted by a registered WindowListener object and responded to as appropriate.
  
  
• The CardLayout manager allows one of a number of Panels to be shown at any one time, and provides facilities to navigate between them.
  
  
• Menu accelerators allow the menus to be operated from the keyboard without having to navigate the menus with the mouse.
