Class KeyEvent<H extends EventHandler>

java.lang.Object
  com.google.web.bindery.event.shared.Event<H>
      com.google.gwt.event.shared.GwtEvent<H>
          com.google.gwt.event.dom.client.DomEvent<H>
              com.google.gwt.event.dom.client.KeyEvent<H>


Type Parameters:: H - The event handler type

All Implemented Interfaces:: HasNativeEvent

Direct Known Subclasses:: KeyCodeEvent, KeyPressEvent

public abstract class KeyEvent<H extends EventHandler>
extends DomEvent<H>
extends DomEvent<H>

Base class for Key events. The native keyboard events are somewhat a mess (http://www.quirksmode.org/js/keys.html), we do some trivial normalization here, but do not attempt any complex patching, so user be warned.
