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.

<BLOCKQUOTE>
<DL>
<P>
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 <code>scrollToReference</code> 
 method.  If the desired URL is not the one currently being
 displayed, the <code>getStream</code> method is called to
 give subclasses control over the stream provided.
 <p>
 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 
 <code>AbstractDocument.getAsynchronousLoadPriority</code>
 that is greater than or equal to zero, the page will be
 loaded on a seperate thread using that priority.
 <p>
 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 <code>setDocument</code>, 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.
 <p>
 If the document is loaded asynchronously, the document
 will be installed into the editor immediately using a
 call to <code>setDocument</code> 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.
 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.

<P>
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.

<P>
Fetch a stream for the given url, which is about to 
 be loaded by the <code>setPage</code> 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.
 <p>
 This method is expected to have the the side effect of
 establising the content type, and therefore setting the
 appropriate EditorKit to use for loading the stream.

<P>
Scroll the view to the given reference location
 (i.e. the value returned by the <code>UL.getRef</code>
 method for the url being displayed).  By default, this
 method only knows how to locate a reference in an
 HTMLDocument.  The implementation calls the
 <code>scrollRectToVisible</code> 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.
