 * GtkBoxChild:
 * @param widget: the child widget, packed into the GtkBox.
 * @param padding: the number of extra pixels to put between this child and its
 *  neighbors, set when packed, zero by default.
 * @param expand: flag indicates whether extra space should be given to this child.
 *  Any extra space given to the parent GtkBox is divided up among all children
 *  with this attribute set to %TRUE; set when packed, %TRUE by default.
 * @param fill: flag indicates whether any extra space given to this child due to its
 *  \p expand attribute being set is actually allocated to the child, rather than
 *  being used as padding around the widget; set when packed, %TRUE by default.
 * @param pack: one of #GtkPackType indicating whether the child is packed with
 *  reference to the start (top/left) or end (bottom/right) of the GtkBox.
 * @param is_secondary: %TRUE if the child is secondary
 *
 * The #GtkBoxChild holds a child widget of #GtkBox and describes how the child
 * is to be packed into the #GtkBox. All fields of this #GtkBoxChild should be
 * considered read-only and they should never be set directly by an application.
 * Use gtk_box_query_child_packing() and gtk_box_set_child_packing() to query
 * and set the #GtkBoxChild.padding, #GtkBoxChild.expand, #GtkBoxChild.fill and
 * #GtkBoxChild.pack fields.
 *
 * Deprecated: 2.22: Use gtk_container_get_children() instead.
