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.

Java Swing Tutorial – Java Swing JEditorPane
If this the stream was an http connection, redirects will be followed and the resulting URL will be set as the Document. Returns the text contained in this TextComponent in terms of the content type of this editor. However, the top right editor pane illustrates a handy, easy-to-use feature: If you want unstyled text, use a text area instead. 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.
That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples.
The kit used in this case is an extension of DefaultEditorKit that produces a wrapped plain text view. IOException – as thrown by the stream being used to initialize See Also: In this case the model would be replaced after it was initialized with the contents of the string. To avoid this, create a new document, getEditorKit. This is defined to be the type associated with the currently installed EditorKit.
It effectively morphs into the proper kind of text editor for the kind of content it is given. Sign up using Email and Password. To force a document reload it is necessary to clear the stream description property of the document.
How to add stylesheet information to a JEditorPane |
A look-and-feel implementation might use this in conjunction with createEditorKitForContentType to install handlers for content types with a look-and-feel bias. If an exception is thrown while attempting to retrieve the text, null will be returned.
To handle this, it is expected that the EditorKit. This is called when a type is requested that doesn’t match the currently installed type. 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. 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.
If there was no registered ClassLoaderClass. Once a prototype EditorKit instance is successfully located, it is cloned and the clone is returned. Returns true if a viewport should always force the height of this Scrollable to match the height of the viewport. This is implemented to call JTextComponent. 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.
The following code shows how this can be done: Sets the currently installed kit for handling content. If the URL contains and reference location, the location will be scrolled to by calling the scrollToReference method.
Creates a handler for the given type from the default registry of editor kits. In this case, the content type will be determined from the URL, and the registered EditorKit for that content type will be set.
Gets the current URL being displayed. In order to use editor panes and text panes, you need to understand the text system, which is described in Text Component Features. Otherwise it calls the superclass method which loads the model as plain text.

Here we list the facts again and provide a bit more detail. Be aware that the document and editor kit might change when using the setPage method. Any old kit is first deinstalled, then if kit is non- nullthe new kit is installed, and a default document created for it. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. IOException – for a null or invalid page specification, or exception from the stream being read See Also: This component uses implementations of the EditorKit to accomplish its behavior.
The listener list is processed last to first. If the text format is known, the editor pane initializes itself with the text found at the URL. This’s a very technical answer, much better than the accepted one. Fetches the currently installed kit for handling content.
This may load either synchronously or asynchronously depending upon the document returned by the EditorKit. Returns true if a viewport should always force the width of this Scrollable to match the width of the viewport.
jeditogpane 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. Next, the code loops over the arrays, inserts the text into the text pane, and specifies the style to use for the inserted text. It the file is loaded directly, the content type would be expected to have been set prior to loading.
