RichTextArea   Click here for complete JavaDoc
The RichTextArea component allows the user to edit rich text.  The rich text format is HTML. A RichTextRenderer compliant object is used to control what commands are available to the user, such as bold, underline or bullets.  The DefaultRichTextRenderer implements RichTextRenderer and can be used on most occasions. Since the component is derived from TextComponent, it data model is a Document.
rta = new RichTextArea(); rta.setHeight(100); rta.setHeightUnits(RichTextArea.PIXEL_UNITS); rta.setWidth(100); rta.setWidthUnits(RichTextArea.PERCENT_UNITS);
Client Browser Support : This component requires IE 5.5 or Mozilla 1.3.  This is because only these browsers have an underlying HTML document editing capability.
