Java Swing Tutorial – Java Swing JEditorPane. A JEditorPane is a text component that can handle different text with style. By default, it can handle plain text. Did you know that you can use CSS styles when displaying HTML in a Java Swing application? It’s pretty cool, and it can help spice up any. You can use either of them, but if it is a rich text editor then I would suggest using the JTextPane. You may also find this topic useful.

Illustrates many text component features, such as undo and redo, document filters, document listeners, caret change listeners, and how to associate editing actions with menus and key strokes.
Newlines For a discussion on how newlines are handled, see DefaultEditorKit. The setPage method can be used to initialize the component from a URL. EditorKit getEditorKit Fetches the currently installed kit for handling content. Replaces the currently selected content with new content represented by the given string. This is a convenience constructor that calls the setContentType and setText methods. Fetches the editor kit to use for the given type of content.
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: Jeditoroane the document is loaded synchronously, it will be filled in with the stream prior to being installed into the editor with a call to setDocumentwhich is bound and will fire a property change jvaa. This jeditorrpane will cause setDocument to be called on behalf of the caller to ensure integrity of the javw state.
You can use either of them, but if it is a rich text editor then I would suggest using the JTextPane. Several facts about editor panes and text panes are scattered throughout that section. The preferred size for JEditorPane is slightly altered from the preferred size of the superclass. This can be reimplemented to use the Java Activation Framework, for example. By default, this simply opens the URL and returns the stream.
Returns true if a viewport should always force the width of this Scrollable to match the width of the viewport. The content type that editor jeditorpanr bound to at any given time is determined by the EditorKit currently installed. The assumption is that the previous content is relatively small, and that the previous content doesn’t have side effects. Notifies all listeners that have registered interest for notification on this event type.
This will be established by a call to the setContentType method. Gets the current URL being displayed. Also see the documentation redistribution policy. If there is no replacement text i.
Returns the text contained in this TextComponent in terms of the content type of this editor. One way is to specify the character set as a parameter of the MIME type.
If your program uses the setPage method, make sure you adjust your code for possible changes to the pane’s document and editor kit instances re-register document listeners on the new document, and so on. Serialized objects of this class will not be compatible with future Swing releases. Swing is not thread safe.
Email Required, but never shown. If scrolling to a reference location is needed for document types other than HTML, this method should be reimplemented. To handle this, it is expected that the EditorKit. The read method can be used to initialize the component from a Reader. You can see an editor pane and a text pane in use by running TextSamplerDemo.
For more information see Swing’s Threading Policy. Any old kit is first deinstalled, then if kit is non- nullthe new kit is installed, and a default document created for it. To avoid this, create a new document, getEditorKit. This is mostly convenience method that can be used as an alternative to calling setEditorKit directly. 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.
The default varies based on the look and feel; to enable it set the client property with this name to Boolean. If there was no registered ClassLoaderClass. Examples and practices described in this page don’t take advantage of improvements introduced in later releases. The prototype EditorKit will be loaded with Class.
Here is the code from the TextSamplerDemo example that creates and initializes a text pane. The code uses the default constructor to create the editor pane, then calls setEditable false so the user cannot edit the text. Creates a JEditorPane that has been initialized to the given text. Sets the type of content that this editor handles. It will also be fired on the event-dispatch thread.
Scrolls the view to the given reference location that is, the value returned by the UL. The registry is created if necessary. This component uses implementations of the EditorKit to accomplish its behavior. Fetches a stream for jeditorrpane given URL, which is about to be loaded by the setPage method. If HTML frames are embedded in the document, the typical response would be to change a portion of the current document.
