In JavaScript you can use return false; or event.returnValue = false; (IE), event.preventDefault(); (FF, Chromium, Opera) in event handler.

With GWT you just use the NativeEvent's preventDefault() method

area.addKeyPressHandler(new KeyPressHandler() {
  @Override
  public void onKeyPress(KeyPressEvent event) {
    if (event.getCharCode() == 13) {
      event.preventDefault();
    }
  }
});
