public class Label
A widget that contains arbitrary text, not interpreted as HTML. This widget uses a <div> element, causing it to be displayed with block layout.
public class HTMLExample implements EntryPoint {

// Create a Label and an HTML widget.
Label lbl = new Label("This is just text. It will not be interpreted "

HTML html = new HTML(
"This is HTML. It will be interpreted as such if you specify "

// Add them to the root panel.
VerticalPanel panel = new VerticalPanel();
