 * @GTK_BUTTONBOX_EXPAND: Buttons expand to fill the box. This entails giving
 *   buttons a "linked" appearance, making button sizes homogeneous, and
 *   setting spacing to 0 (same as calling gtk_box_set_homogeneous() and
 *   gtk_box_set_spacing() manually)
 *
 * Used to dictate the style that a #GtkButtonBox uses to layout the buttons it
