/** A base class for box containers.
 *
 * Abstract base class for horizontal and vertical boxes, which organize a
 * variable number of widgets into a rectangular area.  This is an abstract
 * class and it defers choice of which way the widgets are packed to the screen
 * to the derived classes.  It provides a common interface for inserting
 * widgets to a box indepenently of how it is shown in the screen.
 *
 * Gtk::Box uses a notion of packing. Packing refers to adding widgets with
 * reference to a particular position in a Gtk::Container. There are two
 * reference positions: the start and the end of the box. For a VBox, the start
 * is defined as the top of the box and the end is defined as the bottom.  For
 * a HBox the start is defined as the left side and the end is defined as the
 * right side.  Use repeated calls to pack_start() to pack widgets into a
 * Gtk::Box from start to end. Use pack_end() to add widgets from end to start.
 * You may intersperse these calls and add widgets from both ends of the same
 * Gtk::Box. The last widget added with pack_start() will be placed just before
 * the last widget added with pack_end()
 *
 * Because Gtk::Box is a Gtk::Container, you may also use Gtk::Container::add()
 * to insert widgets, and they will be packed as if with pack_start(). Use
 * Gtk::Container::remove() to remove widgets.
 *
 * Use set_homogeneous() to specify whether or not all children of the Gtk::Box
 * occupy the same amount of space.  Use set_spacing() to determine the minimum
 * space placed between all children in the Gtk::Box.  Use reorder_child() to
 * move a child widget to a different place in the box.  Use
 * set_child_packing() to reset the pack options and padding attributes of any
 * Gtk::Box child. Use query_child_packing() to query these fields.
