public class SMILViewer

extends java.awt.event.WindowAdapter

implements Viewer, java.awt.event.ActionListener

This is a standalone application, SMIL Viewer, showing how to display SMIL presenations. This class shows a deeper approach compared to the SMILApp class, thus giving also more flexibility.

To run this viewer as a standalone application, classpath should include xerces.jar and xml-apis.jar
