+ * @Short_description: A Scrollbar
+ * @Title: GtkScrollbar
+ * @See_also: #GtkAdjustment, #GtkScrolledWindow
+ *
+ * The #GtkScrollbar widget is a horizontal or vertical scrollbar,
+ * depending on the value of the #GtkOrientable:orientation property.
+ *
+ * The position of the thumb in a scrollbar is controlled by the scroll
+ * adjustments. See #GtkAdjustment for the fields in an adjustment - for
+ * #GtkScrollbar, the #GtkAdjustment.value field represents the position
+ * of the scrollbar, which must be between the #GtkAdjustment.lower field
+ * and #GtkAdjustment.upper - #GtkAdjustment.page_size. The
+ * #GtkAdjustment.page_size field represents the size of the visible
+ * scrollable area. The #GtkAdjustment.step_increment and
+ * #GtkAdjustment.page_increment fields are used when the user asks to
+ * step down (using the small stepper arrows) or page down (using for
+ * example the <keycap>PageDown</keycap> key).
