Using the AGUI is similar to using the AWT, in that you organize your user interface
around containers that contain components, and you register event listeners to handle
user-interface events. Two key differences arise, however, especially when using some
of the more sophisticated components provided by Swing. First, Swing's architects
designed Swing's components around the MVC design pattern. Understanding MVC
can make interacting with the more complex Swing components easier. Second, Swing
supports a pluggable look and feel (although the AGUI support does
not
provide the
same functionality).

Note
If you need to learn the basics of programming with Java Swing, as with AWT, I suggest you pick up
a copy of

Sun's documentation on the topic available at

Using the AGUI is similar enough to Swing that with your existing Swing experi-
ence, you should feel right at home. However, there are some differences, including
the following:
