Re: bouncing (AND quick netscape java tip)

Although I didn't see anything wrong, I know it didn't work. I wrote a
little test program to see what the deal was:

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

public class HApplet extends Applet
{
    public void init()
    {
        addMouseListener(
            new MouseAdapter()
            {
                public void mouseClicked(MouseEvent e)
                {
                    System.out.println("hello fool!");
                }
            });
    }
    
}


It uses the mouse listener correctly. and it works.

Quick Tip: You can see what's going on Java-wise in Netscape
communicator! Click the "communicator" menu item, then "tools", then
"Java console". If you've used System.out.printlns in your applets,
they'll print out in the java console.

cheers folks
