WYSIWYG text editor in Java [closed]

Answer 1

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);
