protected voidpropertyChange(java.beans.PropertyChangeEvent evt)

            updateForeground((Color)evt.getNewValue());
        } else if (name.equals("font")) {
            updateFont((Font)evt.getNewValue());
        } else if (name.equals("document")) {
            JComponent comp = getComponent();

        }
private voidupdateFont(java.awt.Font font)

            return;
        }

        if (font == null) {

        } else {
            StyleConstants.setFontFamily(style, font.getName());
            StyleConstants.setFontSize(style, font.getSize());
            StyleConstants.setBold(style, font.isBold());
            StyleConstants.setItalic(style, font.isItalic());
