# ClassViewer: API Documentation

This is a simple example that uses Doclets to generate information that is used by a custom HelpNavigator to provide a simple class navigator.

The current interface has a custom ClassViewer Navigator with two panes. The top pane is a a list of classes and interfaces, organized by package. When a class is selected its basic information is listed in the bottom pane, including a list of the constructors and methods. The HelpSet uses the standard index and search Navigators. The information used by ClassViewer for a given class is loaded when the class is selected, to improve user's feedback.

This example is just a sketch of what could be done and it was done mostly to explain the concept of a HelpNavigator and to debug the specification. There are many ideas for improving it significantly; we hope to implement some of them but, since it is not part of the standard JavaHelp functionality, we cannot promise it. As always, send us your feedback to javahelp-comments@eng.sun.com.
