    @class wxRibbonButtonBar
    
    A ribbon button bar is similar to a traditional toolbar. It contains one or
    more buttons (button bar buttons, not wxButtons), each of which has a label
    and an icon. It differs from a wxRibbonToolBar in several ways:
      @li Individual buttons can grow and contract.
      @li Buttons have labels as well as bitmaps.
      @li Bitmaps are typically larger (at least 32x32 pixels) on a button bar
        compared to a tool bar (which typically has 16x15).
      @li There is no grouping of buttons on a button bar
      @li A button bar typically has a border around each individual button,
        whereas a tool bar typically has a border around each group of buttons.
    
    @beginEventEmissionTable{wxRibbonButtonBarEvent}
    @event{EVT_RIBBONBUTTONBAR_CLICKED(id, func)}
        Triggered when the normal (non-dropdown) region of a button on the
        button bar is clicked.
    @event{EVT_RIBBONBUTTONBAR_DROPDOWN_CLICKED(id, func)}
        Triggered when the dropdown region of a button on the button bar is
        clicked. wxRibbonButtonBarEvent::PopupMenu() should be called by the
        event handler if it wants to display a popup menu (which is what most
        dropdown buttons should be doing).
