Dialog A Dialog is a top-level window with a title and a border that is typically used to take some form of input from the user.
Dimension The Dimension class encapsulates the width and height of a component (in integer precision) in a single object.
Event NOTE: The Event class is obsolete and is available only for backwards compatilibility.
EventQueue EventQueue is a platform-independent class that queues events, both from the underlying peer classes and from trusted application classes.
FileDialog The FileDialog class displays a dialog window from which the user can select a file.
FlowLayout A flow layout arranges components in a left-to-right flow, much like lines of text in a paragraph.
FocusTraversalPolicy A FocusTraversalPolicy defines the order in which Components with a particular focus cycle root are traversed.
Font The Font class represents fonts, which are used to render text in a visible way.
FontMetrics The FontMetrics class defines a font metrics object, which encapsulates information about the rendering of a particular font on a particular screen.
Frame A Frame is a top-level window with a title and a border.

Error Summary
AWTError Thrown when a serious Abstract Window Toolkit error has occurred.
 

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 components 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.
