public class: JEditorPane [javadoc | source]

All Implemented Interfaces:
    Scrollable, Accessible, HasGetTransferHandler, Serializable, MenuContainer, ImageObserver

Direct Known Subclasses:
    JTextPane, HelpContent, FrameEditorPane

A text component to edit various kinds of content. You can find how-to information and examples of using editor panes in Using Text Components, a section in The Java Tutorial.

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.

By default, the following types of content are known:

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.
HTML text. The kit used in this case is the class javax.swing.text.html.HTMLEditorKit which provides HTML 3.2 support.
RTF text. The kit used in this case is the class javax.swing.text.rtf.RTFEditorKit which provides a limited support of the Rich Text Format.

There are several ways to load content into this component.

  1. The setText 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.
  2. The read 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 Base 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.
  3. The setPage 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.

Some kinds of content may provide hyperlink support by generating hyperlink events. The HTML EditorKit will generate hyperlink events if the JEditorPane is not editable (JEditorPane.setEditable(false); 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.

     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();
                 } else {
                     try {
                     } catch (Throwable t) {

For information on customizing how text/html is rendered please see #W3C_LENGTH_UNITS and #HONOR_DISPLAY_PROPERTIES

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).

There are multiple ways to get a character set mapping to happen with JEditorPane.

  1. One way is to specify the character set as a parameter of the MIME type. This will be established by a call to the setContentType method. If the content is loaded by the setPage 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.
  2. 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).

For a discussion on how newlines are handled, see DefaultEditorKit.

Methods from java.lang.Object:
clone,   equals,   finalize,   getClass,   hashCode,   notify,   notifyAll,   toString,   wait,   wait,   wait
Method from javax.swing.JEditorPane Detail:
 public synchronized  void addHyperlinkListener(HyperlinkListener listener) 
    Adds a hyperlink listener for notification of any changes, for example when a link is selected and entered.
 protected EditorKit createDefaultEditorKit() 
    Creates the default editor kit (PlainEditorKit) for when the component is first created.
 public static EditorKit createEditorKitForContentType(String type) 
    Creates a handler for the given type from the default registry of editor kits. The registry is created if necessary. If the registered class has not yet been loaded, an attempt is made to dynamically load the prototype of the kit for the given type. If the type was registered with a ClassLoader, that ClassLoader will be used to load the prototype. If there was no registered ClassLoader, Class.forName will be used to load the prototype.

    Once a prototype EditorKit instance is successfully located, it is cloned and the clone is returned.

 public  void fireHyperlinkUpdate(HyperlinkEvent e) 
    Notifies all listeners that have registered interest for notification on this event type. This is normally called by the currently installed EditorKit if a content type that supports hyperlinks is currently active and there was activity with a link. The listener list is processed last to first.
 public AccessibleContext getAccessibleContext() 
    Gets the AccessibleContext associated with this JEditorPane. For editor panes, the AccessibleContext takes the form of an AccessibleJEditorPane. A new AccessibleJEditorPane instance is created if necessary.
 public final String getContentType() 
    Gets the type of content that this editor is currently set to deal with. This is defined to be the type associated with the currently installed EditorKit.
 public EditorKit getEditorKit() 
    Fetches the currently installed kit for handling content. createDefaultEditorKit is called to set up a default if necessary.
 public static String getEditorKitClassNameForContentType(String type) 
    Returns the currently registered EditorKit class name for the type type.
 public EditorKit getEditorKitForContentType(String type) 
    Fetches the editor kit to use for the given type of content. This is called when a type is requested that doesn't match the currently installed type. If the component doesn't have an EditorKit registered for the given type, it will try to create an EditorKit from the default EditorKit registry. If that fails, a PlainEditorKit is used on the assumption that all text documents can be represented as plain text.

    This method can be reimplemented to use some other kind of type registry. This can be reimplemented to use the Java Activation Framework, for example.

 public synchronized HyperlinkListener[] getHyperlinkListeners() 
    Returns an array of all the HyperLinkListeners added to this JEditorPane with addHyperlinkListener().
 public URL getPage() 
    Gets the current URL being displayed. If a URL was not specified in the creation of the document, this will return null, and relative URL's will not be resolved.
 public Dimension getPreferredSize() 
    Returns the preferred size for the JEditorPane. The preferred size for JEditorPane is slightly altered from the preferred size of the superclass. If the size of the viewport has become smaller than the minimum size of the component, the scrollable definition for tracking width or height will turn to false. The default viewport layout will give the preferred size, and that is not desired in the case where the scrollable is tracking. In that case the normal preferred size is adjusted to the minimum size. This allows things like HTML tables to shrink down to their minimum size and then be laid out at their minimum size, refusing to shrink any further.
 public boolean getScrollableTracksViewportHeight() 
    Returns true if a viewport should always force the height of this Scrollable to match the height of the viewport.
 public boolean getScrollableTracksViewportWidth() 
    Returns true if a viewport should always force the width of this Scrollable to match the width of the viewport.
 protected InputStream getStream(URL page) throws IOException 
    Fetches a stream for the given URL, which is about to be loaded by the setPage method. By default, this simply opens the URL and returns the stream. This can be reimplemented to do useful things like fetch the stream from a cache, monitor the progress of the stream, etc.

    This method is expected to have the the side effect of establishing the content type, and therefore setting the appropriate EditorKit to use for loading the stream.

    If this the stream was an http connection, redirects will be followed and the resulting URL will be set as the Document.StreamDescriptionProperty so that relative URL's can be properly resolved.

 public String getText() 
    Returns the text contained in this TextComponent in terms of the content type of this editor. If an exception is thrown while attempting to retrieve the text, null will be returned. This is implemented to call JTextComponent.write with a StringWriter.
 public String getUIClassID() 
    Gets the class ID for the UI.
 protected String paramString() 
    Returns a string representation of this JEditorPane. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.
 public  void read(InputStream in,
    Object desc) throws IOException 
    This method initializes from a stream. If the kit is set to be of type HTMLEditorKit, and the desc parameter is an HTMLDocument, then it invokes the HTMLEditorKit to initiate the read. Otherwise it calls the superclass method which loads the model as plain text.
  void read(InputStream in,
    Document doc) throws IOException 
    This method invokes the EditorKit to initiate a read. In the case where a ChangedCharSetException is thrown this exception will contain the new CharSet. Therefore the read operation is then restarted after building a new Reader with the new charset.
 public static  void registerEditorKitForContentType(String type,
    String classname) 
    Establishes the default bindings of type to classname. The class will be dynamically loaded later when actually needed, and can be safely changed before attempted uses to avoid loading unwanted classes. The prototype EditorKit will be loaded with Class.forName when registered with this method.
 public static  void registerEditorKitForContentType(String type,
    String classname,
    ClassLoader loader) 
    Establishes the default bindings of type to classname. The class will be dynamically loaded later when actually needed using the given ClassLoader, and can be safely changed before attempted uses to avoid loading unwanted classes.
 public synchronized  void removeHyperlinkListener(HyperlinkListener listener) 
    Removes a hyperlink listener.
 public  void replaceSelection(String content) 
    Replaces the currently selected content with new content represented by the given string. If there is no selection this amounts to an insert of the given text. If there is no replacement text (i.e. the content string is empty or null) this amounts to a removal of the current selection. The replacement text will have the attributes currently defined for input. If the component is not editable, beep and return.
 public  void scrollToReference(String reference) 
    Scrolls the view to the given reference location (that is, the value returned by the UL.getRef method for the URL being displayed). By default, this method only knows how to locate a reference in an HTMLDocument. The implementation calls the scrollRectToVisible method to accomplish the actual scrolling. If scrolling to a reference location is needed for document types other than HTML, this method should be reimplemented. This method will have no effect if the component is not visible.
 public final  void setContentType(String type) 
    Sets the type of content that this editor handles. This calls getEditorKitForContentType, and then setEditorKit if an editor kit can be successfully located. This is mostly convenience method that can be used as an alternative to calling setEditorKit directly.

    If there is a charset definition specified as a parameter of the content type specification, it will be used when loading input streams using the associated EditorKit. For example if the type is specified as text/html; charset=EUC-JP the content will be loaded using the EditorKit registered for text/html and the Reader provided to the EditorKit to load unicode into the document will use the EUC-JP charset for translating to unicode. If the type is not recognized, the content will be loaded using the EditorKit registered for plain text, text/plain.

 public  void setEditorKit(EditorKit kit) 
    Sets the currently installed kit for handling content. This is the bound property that establishes the content type of the editor. Any old kit is first deinstalled, then if kit is non-null, the new kit is installed, and a default document created for it. A PropertyChange event ("editorKit") is always fired when setEditorKit is called.

    NOTE: This has the side effect of changing the model, because the EditorKit is the source of how a particular type of content is modeled. This method will cause setDocument to be called on behalf of the caller to ensure integrity of the internal state.

 public  void setEditorKitForContentType(String type,
    EditorKit k) 
    Directly sets the editor kit to use for the given type. A look-and-feel implementation might use this in conjunction with createEditorKitForContentType to install handlers for content types with a look-and-feel bias.
 public  void setPage(URL page) throws IOException 
    Sets the current URL being displayed. The content type of the pane is set, and if the editor kit for the pane is non-null, then a new default document is created and the URL is read into it. If the URL contains and reference location, the location will be scrolled to by calling the scrollToReference method. If the desired URL is the one currently being displayed, the document will not be reloaded. To force a document reload it is necessary to clear the stream description property of the document. The following code shows how this can be done:
      Document doc = jEditorPane.getDocument();
      doc.putProperty(Document.StreamDescriptionProperty, null);
    If the desired URL is not the one currently being displayed, the getStream method is called to give subclasses control over the stream provided.

    This may load either synchronously or asynchronously depending upon the document returned by the EditorKit. If the Document is of type AbstractDocument and has a value returned by AbstractDocument.getAsynchronousLoadPriority that is greater than or equal to zero, the page will be loaded on a separate thread using that priority.

    If the document is loaded synchronously, it will be filled in with the stream prior to being installed into the editor with a call to setDocument, which is bound and will fire a property change event. If an IOException is thrown the partially loaded document will be discarded and neither the document or page property change events will be fired. If the document is successfully loaded and installed, a view will be built for it by the UI which will then be scrolled if necessary, and then the page property change event will be fired.

    If the document is loaded asynchronously, the document will be installed into the editor immediately using a call to setDocument which will fire a document property change event, then a thread will be created which will begin doing the actual loading. In this case, the page property change event will not be fired by the call to this method directly, but rather will be fired when the thread doing the loading has finished. It will also be fired on the event-dispatch thread. Since the calling thread can not throw an IOException in the event of failure on the other thread, the page property change event will be fired when the other thread is done whether the load was successful or not.

 public  void setPage(String url) throws IOException 
    Sets the current URL being displayed.
 public  void setText(String t) 
    Sets the text of this TextComponent to the specified content, which is expected to be in the format of the content type of this editor. For example, if the type is set to text/html the string should be specified in terms of HTML.

    This is implemented to remove the contents of the current document, and replace them by parsing the given string using the current EditorKit. This gives the semantics of the superclass by not changing out the model, while supporting the content type currently set on this component. The assumption is that the previous content is relatively small, and that the previous content doesn't have side effects. Both of those assumptions can be violated and cause undesirable results. To avoid this, create a new document, getEditorKit().createDefaultDocument(), and replace the existing Document with the new one. You are then assured the previous Document won't have any lingering state.

    1. Leaving the existing model in place means that the old view will be torn down, and a new view created, where replacing the document would avoid the tear down of the old view.
    2. Some formats (such as HTML) can install things into the document that can influence future contents. HTML can have style information embedded that would influence the next content installed unexpectedly.

    An alternative way to load this component with a string would be to create a StringReader and call the read method. In this case the model would be replaced after it was initialized with the contents of the string.
