+ * SECTION:gtkbox
+ * @Short_description: A container box
+ * @Title: GtkBox
+ * @See_also: #GtkFrame, #GtkGrid, #GtkLayout
+ *
+ * The GtkBox widget organizes child widgets into a rectangular area.
+ *
+ * The rectangular area of a GtkBox is organized into either a single row
+ * or a single column of child widgets depending upon the orientation.
+ * Thus, all children of a GtkBox are allocated one dimension in common,
+ * which is the height of a row, or the width of a column.
+ *
+ * GtkBox uses a notion of <emphasis>packing</emphasis>. Packing refers
+ * to adding widgets with reference to a particular position in a
+ * #GtkContainer. For a GtkBox, there are two reference positions: the
+ * <emphasis>start</emphasis> and the <emphasis>end</emphasis> of the box.
+ * For a vertical #GtkBox, the start is defined as the top of the box and
+ * the end is defined as the bottom. For a horizontal #GtkBox the start
+ * is defined as the left side and the end is defined as the right side.
+ *
+ * Use repeated calls to gtk_box_pack_start() to pack widgets into a
+ * GtkBox from start to end. Use gtk_box_pack_end() to add widgets from
+ * end to start. You may intersperse these calls and add widgets from
+ * both ends of the same GtkBox.
+ *
+ * Because GtkBox is a #GtkContainer, you may also use gtk_container_add()
+ * to insert widgets into the box, and they will be packed with the default
+ * values for #GtkBox:expand and #GtkBox:fill. Use gtk_container_remove()
+ * to remove widgets from the GtkBox.
+ *
+ * Use gtk_box_set_homogeneous() to specify whether or not all children
+ * of the GtkBox are forced to get the same amount of space.
+ *
+ * Use gtk_box_set_spacing() to determine how much space will be
+ * minimally placed between all children in the GtkBox. Note that
+ * spacing is added <emphasis>between</emphasis> the children, while
+ * padding added by gtk_box_pack_start() or gtk_box_pack_end() is added
+ * <emphasis>on either side</emphasis> of the widget it belongs to.
+ *
+ * Use gtk_box_reorder_child() to move a GtkBox child to a different
+ * place in the box.
+ *
+ * Use gtk_box_set_child_packing() to reset the #GtkBox:expand,
+ * #GtkBox:fill and #GtkBox:padding child properties.
+ * Use gtk_box_query_child_packing() to query these fields.
+ *
+ * <note><para>
+ * Note that a single-row or single-column #GtkGrid provides exactly
+ * the same functionality as #GtkBox.
+ * </para></note>
