public interface: KeyListener [javadoc | source]

All Implemented Interfaces:
    EventListener

All Known Implementing Classes:
    ToolkitEventMulticaster, KeyHandler, AccessibilityKeyListener, KeyHandler, DnDEventMulticaster, KeyAdapter, Handler, Handler, Handler, KeyHandler, MenuKeyboardHelper, InvocationKeyHandler, AWTEventMulticaster

The listener interface for receiving keyboard events (keystrokes). The class that is interested in processing a keyboard event either implements this interface (and all the methods it contains) or extends the abstract KeyAdapter class (overriding only the methods of interest).

The listener object created from that class is then registered with a component using the component's addKeyListener method. A keyboard event is generated when a key is pressed, released, or typed. The relevant method in the listener object is then invoked, and the KeyEvent is passed to it.
