A text component to edit various kinds of content.
This component uses implementations of the
EditorKit to accomplish its behavior. It effectively
morphs into the proper kind of text editor for the kind
of content it is given. The content type that editor is bound
to at any given time is determined by the EditorKit currently
installed. If the content is set to a new URL, its type is used
to determine the EditorKit that should be used to load the content.
<p>
By default, the following types of content are known:
<dl>
<dt><b>text/plain</b>
<dd>Plain text, which is the default the type given isn't
recognized. The kit used in this case is an extension of
DefaultEditorKit that produces a wrapped plain text view.
<dt><b>text/html</b>
<dd>HTML text. The kit used in this case is the class
<code>javax.swing.text.html.HTMLEditorKit</code>
which provides html 3.2 support.
<dt><b>text/rtf</b>
<dd>RTF text. The kit used in this case is the class
<code>javax.swing.text.rtf.RTFEditorKit</code>
which provides a limited support of the Rich Text Format.
</dl>
<p>
There are several ways to load content into this component.
<ol>
<li>
The <a href="#setText">setText</a> method can be used to initialize
the component from a string. In this case the current EditorKit
will be used, and the content type will be expected to be of this
type.
<li>
The <a href="#read">read</a> method can be used to initialize the
component from a Reader. Note that if the content type is html,
relative references (e.g. for things like images) can't be resolved
unless the <base> tag is used or the <em>Base</em> property
on HTMLDocument is set. In this case the current EditorKit
will be used, and the content type will be expected to be of this
type.
<li>
The <a href="#setPage">setPage</a> method can be used to initialize
the component from a URL. In this case, the content type will be
determined from the URL, and the registered EditorKit for that content
type will be set.
</ol>
<p>
For the keyboard keys used by this component in the standard Look and
Feel (L&F) renditions, see the
<a href="doc-files/Key-Index.html#JEditorPane">JEditorPane</a> key assignments.
<p>
Some kinds of content may provide hyperlink support by generating
hyperlink events. The html EditorKit will generate hyperlink events
if the JEditorPane is <em>not editable</em>
(i.e. <code>JEditorPane.setEditable(false);</code> has been called).
If html frames are embedded in the document, the typical response would be
to change a portion of the current document. The following code
fragment is a possible hyperlink listener implementation, that treats
html frame events specially, and simply displays any other activated
hyperlinks.
<code><pre>
class Hyperactive implements HyperlinkListener {
public void hyperlinkUpdate(HyperlinkEvent e) {
if (e.getEventType() == HyperlinkEvent.EventType.ACTIVATED) {
JEditorPane pane = (JEditorPane) e.getSource();
if (e instanceof HTMLFrameHyperlinkEvent) {
HTMLFrameHyperlinkEvent evt = (HTMLFrameHyperlinkEvent)e;
HTMLDocument doc = (HTMLDocument)pane.getDocument();
doc.processHTMLFrameHyperlinkEvent(evt);
} else {
try {
pane.setPage(e.getURL());
} catch (Throwable t) {
t.printStackTrace();
}
}
}
}
}
</pre></code>
<p>
Culturally dependent information in some documents is handled through
a mechanism called character encoding. Character encoding is an
unambiguous mapping of the members of a character set (letters, ideographs,
digits, symbols, or control functions) to specific numeric code values. It
represents the way the file is stored. Example character encodings are
ISO-8859-1, ISO-8859-5, Shift-jis, Euc-jp, and UTF-8. When the file is
passed to an user agent (JEditorPane) it is converted to the document
character set (ISO-10646 aka Unicode).
<p>
There are multiple ways to get a character set mapping to happen
with JEditorPane.
<ol>
<li>
One way is to specify the character set as a parameter of the MIME
type. This will be established by a call to the
<a href="#setContentType">setContentType</a> method. If the content
is loaded by the <a href="#setPage">setPage</a> method the content
type will have been set according to the specification of the URL.
It the file is loaded directly, the content type would be expected to
have been set prior to loading.
<li>
Another way the character set can be specified is in the document itself.
This requires reading the document prior to determining the character set
that is desired. To handle this, it is expected that the
EditorKit.read operation throw a ChangedCharSetException which will
be caught. The read is then restarted with a new Reader that uses
the character set specified in the ChangedCharSetException (which is an
IOException).
</ol>
<p>
<strong>Warning:</strong>
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is appropriate
for short term storage or RMI between applications running the same
version of Swing. A future release of Swing will provide support for
long term persistence.
