     *
     * The QStringList can be used to pass additional arguments to the part.
     * If the part needs additional arguments, it should take them as
     * name="value" pairs. This is the way additional arguments will get passed
     * to the part from eg. khtml. You can for example emebed the part into HTML
     * by using the following code:
     * <pre>
     *    <object type="my_mimetype" data="url_to_my_data">
     *        <param name="name1" value="value1">
     *        <param name="name2" value="value2">
     *    </object>
     * </pre>
     * This could result in a call to
     * <pre>
     *     createPart( parentWidget, name, parentObject, parentName, "Kparts::Part",
     *                 QStringList("name1="value1"", "name2="value2") );
     * </pre>
     *
     * @returns the newly created part.
     *
     * After creating thte part, you should emit objectCreated( part ),
     * so that KLibFactory can do proper reference counting, and so
     * that KParts::Factory can insert the part's message calatogue for i18n.
