Description
   
    GtkButtonBox is a base class providing a series
    of layout options for buttons packed into 
    GtkHButtonBox and
    GtkVButtonBox container widgets.
   
   
     Please note that in GTK+ 2.0 all reference to spacing 
     will be completely removed; this is because these values are always
     relative in GtkButtonBox classes, and should be
     adjusted internally.
