Changing font to a custom font - styleddocument

Question

hello
i've been trying to change the font in a styleddocument to a custom one that is not registered on the pc
(i'm trying to make an application that holds the fonts in a folder, so that they can be dynamically loaded when needed)
until now nothing worked
i've tried 2 ways atm:
        JTextPane background = new JTextPane();
        StyledDocument styledDoc = background.getStyledDocument();
        if (styledDoc instanceof AbstractDocument) {
            doc = (AbstractDocument)styledDoc;
        } else {
            System.err.println("Text pane's document isn't an AbstractDocument!");
        initAttributes();
        background.setBackground(Color.BLACK);
        background.setEditable(false);
        File file = new File("fonts/mCode15.ttf");
     FileInputStream fis = null;
        Font font = null;
        try {
            fis = new FileInputStream(file);
            font = Font.createFont(Font.TRUETYPE_FONT, fis);
        } catch (FileNotFoundException ex) {
            Logger.getLogger(MatrixWindow.class.getName()).log(Level.SEVERE, null, ex);
        } catch (FontFormatException ex) {
            Logger.getLogger(MatrixWindow.class.getName()).log(Level.SEVERE, null, ex);
        } catch (IOException ex) {
            Logger.getLogger(MatrixWindow.class.getName()).log(Level.SEVERE, null, ex);
        background.setFont(font);    // FAILS
        SimpleAttributeSet attrs = new SimpleAttributeSet();
        StyleConstants.setFontSize(attrs, 12);
        StyleConstants.setBold(attrs, true);
        StyleConstants.setForeground(attrs, Color.WHITE);
        StyleConstants.setFontFamily(font.getFontFamily);      // FAILSdoes anybody know any working solution for CUSTOM fonts?

Answer 1

You should override public Font getFont(AttributeSet attr) method to return proper font with attributes.
See how it works in src of DefaultStyledDocument class.
