  Abstract Windowing Toolkit - Wikipedia, the free encyclopedia
When Java was released, AWT was heavily criticized as one of the weakest components of Java.
An AWT application that might look great on a Windows PC would turn out to be an unusable mess on a Macintosh system, and vice versa.
In the JDK version 2, the AWT's widgets have largely been superseded by those of the Swing toolkit.

 abstract from FOLDOC
In general an interpretation is characterised by the domains used to represent the basic types and the abstract values it assigns to constants (where the constants of a language include primitive functions such as *).
Examples are abstract data types (the representation details are hidden), abstract syntax (the details of the concrete syntax are ignored), abstract interpretation (details are ignored to analyse specific properties).
A parse tree is similar to an abstract syntax tree but it will typically also contain features such as parentheses which are syntactically significant but which are implicit in the structure of the abstract syntax tree.

 Design Patterns and the Java AWT
Toolkits for user interfaces allows the programmer to build the user interface framework in minutes, but designing the interface properly and understanding the entities at work in it requires much more time.
Java and the associated class libraries (AWT and others) are still young, and although the language and the libraries on the whole are well designed, it is more than likely that they will evolve from their present form.
Java AWT doesn't have a component that could be used to view the database hierarchy as the outline of the database browser.

AWT was designed so that each component can play its part in the overall AWT system without needing to duplicate or keep track of the behavior of other parts in the system.
In other windowing systems, UI components are often arranged using hard-coded pixel measurements—put text field tf at 10,30, for example—the same way you used the graphics operations to paint squares and ovals on the screen.
The actual appearance of the AWT components on the screen is determined by two things: the order in which they are added to the panel that holds them, and the layout manager that panel is currently using to lay out the screen.

 [Chapter 10] Understand the Abstract Windowing Toolkit   (Site not responding. Last check: 2007-11-05)
AWT is the largest and most complicated part of the standard Java distribution, so it shouldn't be any surprise that we'll take several chapters (five, to be precise) to discuss it.
While the low-level (possibly native) GUI toolkits may be complex, you won't have to work with them directly unless you want to port AWT to a new platform or provide an alternative "look and feel" for the built-in components.
AWT is very different from what many people are used to and lacks some of the advanced features other GUI environments provide (at least for now).

 AWT - Abstract Windows Toolkit
The AWT includes imaging tools, data transfer classes, GUI components, containers for GUI components, an event system for handling user and system events among parts of the AWT, and layout managers for managing the size and position of GUI components in platform-independent designs.
This is a toolkit used to implement windowing functions within the Java language.

The Remote Abstract Windowing Toolkit (RAWT) for Java is an implementation of AWT for Java which allows a Java application running on one machine to display its GUI components on a remote machine.
Therefore, prior to using Remote AWT at the client side, the user should ensure that the default value for the Remote AWT Port does not interfere with other applications on the GUI side.

 2.1 The Abstract Windows Toolkit   (Site not responding. Last check: 2007-11-05)
The AWT is named as an abstract toolkit as it provides only the essential components and functionality which are common to all major windowing systems.
Java abstracts the essential behaviour of a push button and provides an API which is presented to the developer in the AWT.
However the precise physical appearance is determined by the native windowing environment.

 Abstract Window Toolkit - a Whatis.com definition - see also: AWT   (Site not responding. Last check: 2007-11-05)
Abstract Window Toolkit (AWT) is a set of application program interfaces (APIs) used by Java programmers to create graphical user interface (GUI) objects, such as buttons, scroll bars, and windows.
AWT is part of the Java Foundation Classes (JFC) from Sun Microsystems, the company that originated Java.
A more recent set of GUI interfaces called Swing extends the AWT so that the programmer can create generalized GUI objects that are independent of a specific operating system's windowing system.

Not only is the AWT a better API for developing Windows applications, it is a better API for programming window-based applications on platforms ranging from Motif to OS/2.
Swing extends AWT by supplying many more types of GUI components, providing 100% pure Java implementations of these components, and allowing the appearance and behavior of these components to be easily tailored.
Because of this, the AWT components behave more consistently across different platforms and are capable of providing additional features not supported by their native windowing platforms.

Theoretically this should be possible, because the AWT can in theory have many different implementations (that is why it was named the Abstract Windowing Toolkit).

 JFC: An in-depth look at Sun's successor to AWT
The original method for providing GUI functions in Java was the Abstract Windowing Toolkit (AWT), which relied on native peers (Mac system buttons on a Mac, Motif buttons on Solaris, and so on) in order to achieve consistent functionality across systems.
The JDK 1.2 AWT should solve a lot of the bug issues, but in order to solve the problem of consistent appearance across platforms, another solution is needed.
The AWT continues to serve as a provider of a peer-based UI that scales across a greater diversity of devices.

The main difference between the FX classes and the AWT graphics classes is that the FX classes use extensible objects.
For instance, in standard Java AWT programming you select Color and Font objects into a graphics context (this is also the way you do it in AFC).
Unlike the AWT classes, however, the FX classes are not limited to system-defined standards.

In Java, a frame is a window that has nice borders, various buttons along the top border, and other built in things.
What you usually call a "window" Java calls a "frame." A frame is a container object, so GUI components can be placed in it.

For example, if you wished to provide an indicator bar to provide the user with feedback about how much of a file had been parsed, you would have to alter thread priorities and explicitly force certain tasks to stop and allow others to run.
The reason for this is that threads are at the core of the Java AWT system.
The thread priorities assigned to AWT components are relatively small however.

You can be notified when a key is pressed and when it is released; when the mouse enters the applet window and when it leaves the applet window; when the mouse button is pressed and when it is released; and when the mouse moves and when it is dragged (moved with the button held down).

Java's Abstract Windowing Toolkit (AWT) provides support for programs that use Graphical User Interfaces (GUIs), rather than simply communicating with the user via the keyboard or via files.
Read about the Component methods, and use the appropriate ones so that the background color of the new window is red, and the color of the text is blue.
The mechanism that the Java AWT provides to support this is the creation of Listeners, which have methods that are invoked in response to user actions.
