    \brief View class for MToolBar widget when it is used in tab mode.

    \section MToolbarTabViewOverview Overview
        MToolbarTabView is used to visualize mutually exclusive latch-down type of buttons
        placed into the MToolBar.

        The outlook of toolbar can be changed using the styling attributes defined
        in MToolbarStyle and MWidgetStyle.

    \section MToolBarTabInteractions Interactions
        - The toolbar has currently no interactions by itself: the interactions are
          determined by the UI controls that are placed inside the toolbar.
        - The toolbar can be affected by possible interactions of going to and from the
          full screen mode; this would set the visibility of the toolbar on and off.
        - Setting the visibility of the toolbar on/off should be accompanied by a
          (sliding) transition, hiding and revealing the toolbar.
