public class JextTextArea
extends org.gjt.sp.jedit.textarea.JEditTextArea
implements javax.swing.event.UndoableEditListener, javax.swing.event.DocumentListener

Extending JEditTextArea allow us to support syntax colorization. We also implement some listeners: for the caret, for the undos and redos, for the keys (indent) and for the modifications which can occures in the text. This component provides its own methods to read and save files (even to zip them).
