Appending richtext to JTextPane using StyledDocument.insertString doesn't preserve fonts

Question

I don't know if what I'm trying to do is possible or not.

I have console where I want to append formatted text declared like this:

private final JTextPane statusText = new JTextPane();

I got a reference to its styled document like this:

private StyledDocument statusDocument = statusText.getStyledDocument();

I defined a few attributes :

private final SimpleAttributeSet gray;
private final SimpleAttributeSet black;
private final SimpleAttributeSet red;

and a helper method:

private void appendStatusText(String text, SimpleAttributeSet attribute) {
        final String finalText = text;
        final SimpleAttributeSet finalAttribute = attribute;
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                try {
                    statusDocument.insertString(statusDocument.getLength(), finalText, finalAttribute);
                } catch (BadLocationException e) {
                    log.error("Cannot add " + finalText, e);
                }
            }
        });
    }

I want to use appendStatusText with one of the attributes (gray, red, black) and some text, but all it's showing is in gray, I'm expecting multicolors.

Can you help please.

PS: I got the code from the question here

maybe is/are there another issue(s), please edit you post with a [SSCCE](http://sscce.org/) — mKorbel, Apr 17 '12 at 15:12
@mKorbel Ok, I'll try to prepare a SSCCE, but first, can you please confirm that it's ok to mix and match different SimpleAttributeSet instances with parts of the text added to a JTextPane? — Charbel, Apr 17 '12 at 15:16
no I think that there isn't issue, another question isn't something, somehow un_clear from (@camickr's) describtion), you can [(pretty to) use one of those two codes for your SSCCE](http://stackoverflow.com/questions/9650992/how-to-change-text-color-in-the-jtextarea/9651404#9651404) — mKorbel, Apr 17 '12 at 15:27
looks like the error is somewhere else, I used the SSCCE you suggested, and modified it, and now it behaves as i expect. I'll keep investigating, thanks — Charbel, Apr 17 '12 at 16:48
the problem was that the text panel had setEnabled to false, which had the effect of everything appearing gray... — Charbel, Apr 19 '12 at 09:51

The initDocument() method of TextComponentDemo shows one approach to constructing such a document. The example appears among the Examples That Use Text Panes and Editor Panes in the tutorial article How to Use Editor Panes and Text Panes.

You have to define your SimpleAttributeSet and then add the attributes you want, like so:

private SimpleAttributeSet red = new SimpleAttributeSet();      
red.addAttribute(StyleConstants.CharacterConstants.Foreground, Color.red);
