GWT register key event from a text field

Question

Hey, I'm running GWT on ubuntu and trying to learn by following the tutorial guide found on Google . I have some problem with making a textfield register when user hit the enter button. It works with specificing arbitrary character, so I don't think it is any problem with the code. So it probably is that KeyCodes.KEY_ENTER isn't supported in linux? What else can I write instead to make it read when user hit enter?

    newSymbolTextBox.addKeyPressHandler(new KeyPressHandler() {
      public void onKeyPress(KeyPressEvent event) {
        if (event.getCharCode() == KeyCodes.KEY_ENTER) {
          addStock();
          System.out.println("Foo");
        }
      }
    });

Use the getKeyCode() method that you'll find on the native event.

if (event.getNativeEvent().getKeyCode() == KeyCodes.KEY_ENTER)
  System.out.println("Foo");

If you think that KeyCodes.KEY_ENTER isn't supported in linux you can just replace it by:

event.getCharCode() == 13
