Applet that uses processXxx methods to print detailed reports on mouse events. Illustrates low-level alternative to handling events with listeners.

import java.applet.Applet;
import java.awt.*;
import java.awt.event.*; 

/** Prints non-detailed reports of mouse events.
 *  Uses the low-level processXxxEvent methods instead
 *  of the usual event listeners.
