How to save a StyledDocument from textPane into a .doc file?

Question

I don't know if this is even possible, but what I would like to do is to save a Styled Document (user can change text: bold, underline, italic and 3 sizes of font) in a .doc file - so he could open it later on his own with any other text editor that supports styled text.

I wrote the code below... the editor works, I can apply the styles on the text but when I save, it saves the text just black, with no styles. I can't figure out where is the problem. Maybe the actions don't save. I tried with writer and with buffered writer but it didn't work. I also tried to use HTML editor kit and it didn't work at all - it saved a blank document.

Maybe anyone has an idea how can I save the styles? Appreciate the help :)

public class EditFrame extends javax.swing.JFrame {

JFrame frameEdit = this;
File file; //A file I would like to save to -> fileName.doc
StyledDocument doc;   
HashMap<Object, Action> actions;
StyledEditorKit kit;

public EditFrame() {
    super();
    initComponents();
    JMenu editMenu = createEditMenu();
}

protected JMenu createEditMenu() {
    JMenu menu = editMenu;

    Action action = new StyledEditorKit.BoldAction();
    action.putValue(Action.NAME, "Bold");
    menu.add(action);

    action = new StyledEditorKit.ItalicAction();
    action.putValue(Action.NAME, "Italic");
    menu.add(action);

    //...

    return menu;
}

//I'm guessing this doesn't work correctly too (doesn't read styles), but this is another subject :)
public void readFile(File f) {
    try {
        BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(f), "windows-1250"));
        textPane.read(reader, null);
        textPane.requestFocus();
    } catch (IOException ex) {
        Logger.getLogger(EditFrame.class.getName()).log(Level.SEVERE, null, ex);
    }
}

//SAVE METHOD
private void save(java.awt.event.ActionEvent evt) {                      
    try {
        BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream(file));
        kit = (StyledEditorKit) textPane.getEditorKit();
        doc = (StyledDocument) textPane.getDocument();
        kit.write(out, doc, 0, doc.getLength());
    } catch (FileNotFoundException ex) {
        Logger.getLogger(EditFrame.class.getName()).log(Level.SEVERE, null, ex);
    } catch (UnsupportedEncodingException | BadLocationException ex) {
        Logger.getLogger(EditFrame.class.getName()).log(Level.SEVERE, null, ex);
    } catch (IOException ex) {
        Logger.getLogger(EditFrame.class.getName()).log(Level.SEVERE, null, ex);
    }
}                     

public static void main(String args[]) {
    java.awt.EventQueue.invokeLater(new Runnable() {
        public void run() {
            new EditFrame().setVisible(true);
        }
    });
}
}

Answer 1

You can use RTFEditorKit, which supports Rich Text Format (RTF). Lots of word processors, including MS Word, can work with this format. Stick with write() to an OutputStream, which writes "a format appropriate for this kind of content handler." The other one that uses a Writer writes "to the given stream as plain text."

Why is StyledEditorKit not working?

StyledEditorKit gets its write() implementation from DefaultEditorKit, "which treats text as plain text." StyledEditorKit stores styled text internally, but it doesn't know about any external format. You have to go to one of the subclasses, HTMLEditorKit or RTFEditorKit, to get something that override's the default write(). The overridden method knows how to transform the internal format to an external format, like RTF.
