Base class for GtkHButtonBox and GtkVButtonBox.
GtkButtonBox is a base class underlying
GtkVButtonBox, that provides some methods to control
the button layout within those widgets. One of this methods is
set_layout() , that applies one of
the GtkButtonBoxStyle layouts to the button box. Another
one is set_child_secondary() , that
causes the child to appear in a secondary group of the button box.
The main purpose of GtkButtonBox is to make sure the
children have all the same size. Therefore it ignores the homogeneous
property which it inherited from GtkBox, and always behaves as if
homogeneous was true.
