     * or implicitly via their xtypes, and can be {@link #add}ed dynamically.
     * Some items have shortcut strings for creation:
     *
    Shortcut  xtype          Class                  Description
    '->'      'tbfill'       {@link Ext.Toolbar.Fill}       begin using the right-justified button container

    ' '       'tbspacer'     {@link Ext.Toolbar.Spacer}     add horiztonal space between elements
     *
