If scrolling to a reference location is needed for document types other than HTML, this method should be reimplemented. Originally posted by Greg Whelan: You can find how-to information and examples of using editor panes in Using Text Componentsa section in The Java Tutorial.

If you need a fully-fledged help system, take a look at the javahelp project. The setPage method only supports URLs which does offer one means of achieving the desired functionality: Creates a handler for the given type from the default registry of editor kits.
This can be reimplemented to do useful things like fetch the stream from a cache, monitor the progress of the stream, etc. This is a convenience constructor that calls the setContentType and setText methods. Replaces the currently selected content with new content represented by the given string. Instead, a program would use an editor pane to save a document which would then be used to initialize the text pane.

Adds a hyperlink listener for notification displau any changes, for example jedltorpane a link is selected and entered. The TextSamplerDemo example barely begins to demonstrate the capabilities of editor panes and text panes. If the text format is known, the editor pane initializes itself with the text found at the URL. This will be established by a call to the setContentType method.
Next, the code creates the URL object, and calls the setPage method with it.
Some formats such as HTML can install things into the document that can influence future contents. If an exception is thrown while attempting to retrieve the text, null will be returned. 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.
The returned string may be empty but may not be null. May I ask what ojbect you use to call showPage String method?
Sign up using Facebook. It effectively morphs into the proper kind of text editor for the kind of content it is given.

The class will be dynamically loaded later when actually needed using the given ClassLoaderand can be safely changed before attempted uses to avoid loading unwanted classes. A look-and-feel implementation might use displqy in conjunction with createEditorKitForContentType to install handlers for content types with a look-and-feel bias.
Two Swing classes support styled text: The implementation calls the scrollRectToVisible method to accomplish the actual scrolling. To avoid this, create a new document, jeditopane. If the type was registered with a ClassLoaderthat ClassLoader will be used to load the prototype.
This has the side effect of changing the model, because the EditorKit is the source of how a particular type of content is modeled. The content type that editor is bound to at any given time is determined by the EditorKit currently installed.
Here is the complete code which I am using. Returns the text contained in this TextComponent in terms of the content type of this editor. NullPointerException – if the type parameter is null See Also: Frank [This message has been edited by Frank Hale edited June 08, Here is the code which will load an HTML page into a editorpane when passed a html file on your hard drive: This is called when a type is requested that doesn’t match the currently installed type.
Email Required, but never shown.
In this case the model would be replaced after it was initialized with the contents of the string. It represents the way the file is stored. Any old kit is first deinstalled, then if kit is non- nullthe new kit is installed, and a default document created for it. I displya a little modification if the program should run outside of netbeans. Returns true if a viewport should always force the height of this Scrollable to match the height of the viewport.
IOException – for a null or invalid page specification, or exception from the stream being read See Also: Returns the preferred size for the JEditorPane. Here is the code from TextSamplerDemo.
