我如何对JEditorPane文本更改做出反应？

Question

I'm working to build an editor. I'd like to know whether the text in JEditorPane is modified or not. How can I react to editor pane text changes?

The following code seems not work.

JEditorPane editorConfig = new JEditorPane();

editorConfig.getDocument().addDocumentListener(new DocumentListener(){

    @Override
    public void insertUpdate(DocumentEvent e) {
        System.out.println("insertUpdate called");
        Dialogc.this.refreshTitle();
    }

    @Override
    public void removeUpdate(DocumentEvent e) {
        System.out.println("removeUpdate called");
        Dialogc.this.refreshTitle();
    }

    @Override
    public void changedUpdate(DocumentEvent e) {
        System.out.println("changedUpdate");
        Dialogc.this.refreshTitle();
    }               
});

Thanks very much for your feedback; the code is right for document update. The code did not work because the document of JTextArea are changed in the coming logic.

Thanks Klaus
