A widget that can contain arbitrary HTML. This widget uses a <span> element, causing it to be displayed with inline layout.
If you only need a simple label (text, but not HTML), then the {@link com.google.gwt.user.client.ui.Label} widget is more appropriate, as itdisallows the use of HTML, which can lead to potential security issues if not used properly.
Built-in Bidi Text Support
This widget is capable of automatically adjusting its direction according to its content. This feature is controlled by {@link #setDirectionEstimator} orpassing a DirectionEstimator parameter to the constructor, and is off by default.
