Swing components
Swing is name given to the set of Java GUI components available in the
Java 1.2 API. These components can not be displayed in a bare bones
Netscape or Internet Explorer browser. To display them the user must either
have the Swing libraries installed on their PC OR the applet must be created
using the Java Plugin option and the user must have the Java Plugin installed.
Tree
This is a standard tree structure. The node images can be set to user supplied
images. The tree will open up to look like it does when it was last saved in AppletPainter.
