Class Overview

A widget that can contain arbitrary HTML. This widget uses a <div> element, causing it to be displayed with block layout.

If you only need a simple label (text, but not HTML), then the Label widget is more appropriate, as it disallows 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 setDirectionEstimator(boolean) or passing a DirectionEstimator parameter to the constructor, and is off by default.

CSS Style Rules

.gwt-HTML { }
