 * The VScrollbar displays a vertical scrollbar with a slider and a pair of
 * arrow buttons. To create a scrollbar, you must specify the beginning and
 * ending values, the size of the slider, an initial slider position, and how
 * far the slider should move when the mouse clicks the slot.

 * @deprecated This class is part of the java-gnome 2.x family of libraries,
 *             which, due to their inefficiency and complexity, are no longer
 *             being maintained and have been abandoned by the java-gnome
 *             project. This class may in the future have an equivalent in
 *             java-gnome 4.0, try looking for
 *             <code>org.gnome.gtk.VScrollBar</code>.
 *             You should be aware that there is a considerably different API
 *             in the new library: the architecture is completely different
 *             and most notably internals are no longer exposed to public view.
