/**
    @class wxRibbonToolBar
    
    A ribbon tool bar is similar to a traditional toolbar which has no labels.
    It contains one or more tool groups, each of which contains one or more
    tools. Each tool is represented by a (generally small, i.e. 16x15) bitmap.
    
    @beginEventEmissionTable{wxRibbonToolBarEvent}
    @event{EVT_RIBBONTOOLBAR_CLICKED(id, func)}
        Triggered when the normal (non-dropdown) region of a tool on the tool
        bar is clicked.
    @event{EVT_RIBBONTOOLBAR_DROPDOWN_CLICKED(id, func)}
        Triggered when the dropdown region of a tool on the tool bar is
        clicked. wxRibbonToolBarEvent::PopupMenu() should be called by the
        event handler if it wants to display a popup menu (which is what most
        dropdown tools should be doing).
