/*!
 * \brief The MPSStyle class
 * \details
 * M(enu)P(anel)S(idebar)Style is an internal style shared in several
 * UKUI desktop applications, such as UKUI Menu, UKUI Panel and UKUI Sidebar, etc.
 *
 * Usually, applications use the styles which have been installed as qstyle plugin in
 * UKUI desktop environment, such as ukui-white and ukui-black. However one style may
 * be not enough for UKUI3.0 desgin. The menu, panel and sidebar desgin is Noticeably
 * different from the common style which we used in peony or other qt's applications.
 * To integrate the unique style into the theme, I came up the idea of internal styles,
 * and combine them with current platform theme's frameworks. So it will Looks like a
 * whole style.
