+ * SECTION:gtkspinbutton
+ * @Title: GtkSpinButton
+ * @Short_description: Retrieve an integer or floating-point number from
+ * the user
+ * @See_also: #GtkEntry
+ *
+ * A #GtkSpinButton is an ideal way to allow the user to set the value of
+ * some attribute. Rather than having to directly type a number into a
+ * #GtkEntry, GtkSpinButton allows the user to click on one of two arrows
+ * to increment or decrement the displayed value. A value can still be
+ * typed in, with the bonus that it can be checked to ensure it is in a
+ * given range.
+ *
+ * The main properties of a GtkSpinButton are through an adjustment.
+ * See the #GtkAdjustment section for more details about an adjustment's
+ * properties.
+ *
+ * <example>
+ * <title>Using a GtkSpinButton to get an integer</title>
