Metalworks is a simple Swing-based simulated e-mail
application. It shows off several features of Swing, including
JInternalFrame, JTabbedPane, JFileChooser, JEditorPane, and
JRadioButtonMenuItem. Metalworks is optimized to work with the
Java look and feel (codenamed "Metal") and shows use of several
features, such as themes, that are specific to the Java look and
feel.
