- * The #GtkScrollbar widget is the base class for #GtkHScrollbar and
- * #GtkVScrollbar. It can be used in the same way as these, by setting
- * the "orientation" property appropriately.
+ * 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
