The more complex text " + "components use a more sophisticated model that implements the " + "StyledDocument interface. StyledDocument is a sub-interface of " + "Document that contains methods for manipulating attributes that " + "control the way in which the text in the document is displayed. " + "The Swing text package contains a concrete implementation of " + "StyledDocument called DefaultStyledDocument that is used as the " + "default model for JTextPane and is also the base class from which " + "more specific models, such as the HTMLDocument class that handles " + "input in HTML format, can be created. In order to make use of " + "DefaultStyledDocument and JTextPane, you need to understand how " + "Swing represents and uses attributes.\n"; }
