/**
    @class wxRibbonBar

    Top-level control in a ribbon user interface. Serves as a tabbed container
    for wxRibbonPage - a ribbon user interface typically has a ribbon bar,
    which contains one or more wxRibbonPages, which in turn each contain one
    or more wxRibbonPanels, which in turn contain controls.
    
    While a wxRibbonBar has tabs similar to a wxNotebook, it does not follow
    the same API for adding pages. Containers like wxNotebook can contain any
    type of window as a page, hence the normal procedure is to create the
    sub-window and then call wxBookCtrlBase::AddPage(). As wxRibbonBar can only
    have wxRibbonPage as children (and a wxRibbonPage can only have a
    wxRibbonBar as parent), when a page is created, it is automatically added
    to the bar - there is no AddPage equivalent to call.
    
    After all pages have been created, and all controls and panels placed on
    those pages, Realize() must be called.
