// Swing Demo - A simple applet using Swing components and simple
// graphics (no Java2D).  Compare this program with AwtDemo.
// This JApplet uses JButtons, a JLabel, and a JPanel instead of
// a Canvas for the static inner class.  (Note using a JComponent
// instead would have no background, which always appears transparent.)
//
// This program adapted from Figure 5.3, p. 199, from Art Gittleman's
// book "Internet Applications With the Java 2 Platform", (C) 2001
// Scott/Jones Inc.
//
// Written by Wayne Pollock, Tampa Florida USA, 2/2001.
