from KoStyleManager.h:


    /**
     * Return a paragraphStyle by its id.
     * From documents you can retrieve the id out of each QTextBlockFormat
     * by requesting the KoParagraphStyle::StyleId property.
     * @param id the unique Id to search for.
     * @see KoParagraphStyle::styleId()
     */
    KoParagraphStyle *paragraphStyle(int id) const;
