Package java.awt Description

Contains all of the classes for creating user interfaces and for painting graphics and images. A user interface object such as a button or a scrollbar is called, in AWT terminology, a component. The Component class is the root of all AWT components. See Component for a detailed description of properties that all AWT compo nents share.

Some components fire events when a user interacts with the components. The AWTEvent class and its subclasses are used to represent the events that AWT components can fire. See AWTEvent for a description of the AWT event model.

A container is a component that can contain components and other containers. A con tainer can also have a layout manager that controls the visual placement of components in the container. The AWT package contains several layout manager classes and an interface for building your own layout manager. See Container and LayoutManager for more information. ##### FILL IN ANY SPECS NEEDED BY JAVA COMPATIBILITY KIT #####
