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

Answer 1

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.
