public abstract class KeyAdapter extends Object implements KeyListener
Extend this class to create a
KeyEvent listener and override the
methods for the events of interest. (If you implement the
KeyListener interface, you have to define all of the methods in
it. This abstract class defines
null methods for them all, so
you only have to define methods for events you care about.)
Create a listener object using the extended class and then register it
with a browser using the browser's
addKeyListener method. When a
keyboard event occurs, the relevant method in the listener object is
invoked and the KeyEvent is passed to it.
