 *   (on the left for a HBox, or the top for a VBox).
 * @GTK_BUTTONBOX_END: Buttons are grouped towards the end of the box,
 *   (on the right for a HBox, or the bottom for a VBox).
 * @GTK_BUTTONBOX_CENTER: Buttons are centered in the box. Since 2.12.
 * @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). Since 3.12.
 *
 * Used to dictate the style that a #GtkButtonBox uses to layout the buttons it
 * contains.
