JEditorPane Class
The
JEditorPane
class provides the ability to display and edit multiple-attributed text. While
the
JTextField
and
JTextArea
support only single-color, single-font content, the
JEditorPane
allows you to tag your content with various styles (such as bold, italics, 14-point Helvetica,
right-justified paragraphs) or with the appearance of an HTML viewer, as shown in Figure 15-19.

Note
The HTML support for
JEditorPane
is only at the HTML 3.2 level with some extensions, whereas
HTML 4.0x is the current version as of this writing. Cascading Style Sheets (CSS) are partially supported.
The
JEditorPane
supports the display and editing of multiple-attributed text through the
help of an
EditorKit
specific to the text-markup mechanism. Predefined kits exist to support
raw text, HTML documents, and Rich Text Format (RTF) documents. Because the content is
multiple-attributed, the
PlainDocument
model is no longer sufficient. Instead, Swing provides a
StyledDocument
in the form of the
DefaultStyledDocument
class for maintaining the document
model. The remaining part of the mix is the new
HyperlinkListener
/
HyperlinkEvent
event-
handling pair for monitoring hyperlink operations within the document.
