  42 /**
  43     @class wxRibbonBar
  44
  45     Top-level control in a ribbon user interface. Serves as a tabbed container
  46     for wxRibbonPage - a ribbon user interface typically has a ribbon bar,
  47     which contains one or more wxRibbonPages, which in turn each contain one
  48     or more wxRibbonPanels, which in turn contain controls.
  49
  50     While a wxRibbonBar has tabs similar to a wxNotebook, it does not follow
  51     the same API for adding pages. Containers like wxNotebook can contain any
  52     type of window as a page, hence the normal procedure is to create the
  53     sub-window and then call wxBookCtrlBase::AddPage(). As wxRibbonBar can only
  54     have wxRibbonPage as children (and a wxRibbonPage can only have a
  55     wxRibbonBar as parent), when a page is created, it is automatically added
  56     to the bar - there is no AddPage equivalent to call.
  57
  58     After all pages have been created, and all controls and panels placed on
  59     those pages, Realize() must be called.
