How to add a <h2> element to a panel?

How ca开发者_Python百科n I add a HTML Element to a GWT Panel?

Just do it this way

HTML html = new HTML("<h2>Headline</h2>");

yourpannel.add(html);

OR

RootPanel.get().add(html);

(Supposing your GWT Panel is a HTMLpanel....)

I'd suggest to take a look at UiBinder.
