WYSIWYG text editor in Java [closed]

Answer 1

• Here's the link: JRichTextEditor
• It's open source (LGPL).
• You can do whatever you want with it. Just clone it from github. It is extensible.
• It comes with quite some features, but enhancements are welcome. It's a swing component, depends on iText 2.1.7 (which is still LGPL) and other libraries (e.g. xerces). One notable feature is the possibility to add mark-points/ranges of any class. Which can be used for hyperlinks or whatever. In the library there's also a Help application.

Answer 2

RSyntaxTextArea

I've used this component and it works well. It is LGPL and it is based on javax.swing.text package (javax.swing.text.EditorKit). Since it is a Swing component it can be integrated in your application in a few lines of code :

RSyntaxTextArea textArea = new RSyntaxTextArea();
textArea.setSyntaxEditingStyle(SyntaxConstants.SYNTAX_STYLE_JAVA);
RTextScrollPane sp = new RTextScrollPane(textArea);

Answer 3

I needed the same thing for our application, did a research and found two more products EKit and Metaphase Editor, based on Charles Bell's HTMLDocumentEditor, both under LGPL license and looking good.

But I did not test them. These days we shall see what we choose.

Answer 4

The Eclipse project has resurrected Vex (Visual Editor for XML)

From the wiki page:

• Vex leverages many of the mature plug-ins that make up the Eclipse Java IDE such as the CVS interface, document searching and bookmarking facilities, and searchable help system.
• The Eclipse platform implements a sophisticated plug-in architecture, allowing Vex to be extended with third-party or custom, in-house plug-ins.
• Vex is available with native look-and-feel for many platforms, including Windows, Linux/GTK, and Macintosh OS-X/Carbon.
• Java developers using the Eclipse IDE can instal Vex into their IDE as a plug-in, making it easy to maintain software documentation or other XML files with Vex.
• Vex is reusable: The Vex editor widget is available as a pure Java, cross-platform component with bindings SWT. Developers can re-use this widget, for example as an RCP application.

Version 1.0 has been released in 2012, an 1.1 is planned for 2013.

Answer 5

JWebEngine

I recommend JWebEngine. It is the only one that I know that passes the ACID1 browser test and the mail-acid test. Most other Java HTML editors are based on the javax.swing.text.html.HTMLDocument and have all the same bugs. The support of CSS is very poor with HTMLDocument. JWebEngine has very good support for viewing HTML with CSS.

• Link to the website. There are also online samples.
• Commercial license
• It is very simple to extend. The vendor is using it for many different things like editor, HTML printing engine, showing custom placeholders, etc. There is no problem with the visibility of classes like with the Sun HTMDocument.
• It based on javax.swing.text.JEditorPane or javax.swing.text.JTextPane and you can use it together with third party tools like the spell checker JOrtho.
• It is pure Java and runs on all platform with Java SE 5 or higher. It also run in non-signed applets.
