Foil 109 Structure of the java.awt GUI Components - I

From CRPC Lectures on Java Language Applets Graphics CRPC Annual Meeting Tutorial -- May 14,1996. by Geoffrey C. Fox
1 In Java, the GUI (Graphical User Interface) is built hierarchically in terms of Components -- one Component nested inside another starting with the smallest Buttons, including Menus, TextFields etc. and ending with full Window divided into Frames, MenuBars etc.
2 Not all useful Classes are inherited from Component. For instance Menu inherits from MenuComponent (interface) --> MenuItem --> Menu
3 One also needs a set of methods and classes to define the layout of the Components in a particular Panel
4 LayoutManager is a java.awt interface with several particular layout strategies implemented as classes under this interface
5 The Container class has methods to interact with LayoutManager classes
