Hi Corrado,
I have an idea to makes a console system in Java.
Since System.out and System.in can't capture KeyEvent.
But in a Console System, it is very important. I would like to do it in this
system.
public class Console extends java.awt.Component;
It can send Key Event to Console and allow us to customize the screen
layout.
most important, if someone has written a Java application depends on it,
we can still write a implement on Linux, Win9X so that it can allows people
to run it Linux.
Regards,
Hilary
