</h1><div class="doc"><p>The <code><a href="Graphics-UI-Gtk-Abstract-Scrollbar.html#t:Scrollbar">Scrollbar</a></code> widget is an abstract base class for
<code>Graphics.UI.Gtk.Scrolling.HScrollbar</code> and
<code>Graphics.UI.Gtk.Scrolling.VScrollbar</code>. It is not very useful in itself.
</p><p>The position of the thumb in a scrollbar is controlled by the scroll
adjustments. See <code>Graphics.UI.Gtk.Misc.Adjustment</code> for the fields in an
adjustment - for
<code><a href="Graphics-UI-Gtk-Abstract-Scrollbar.html#t:Scrollbar">Scrollbar</a></code>, the "value" field represents the position of the scrollbar,
which must be between the "lower" field and "upper - page_size." The
"page_size" field represents the size of the visible scrollable area. The
"step_increment" and "page_increment" fields are used when the user asks
to step down (using the small stepper arrows) or page down (using for
example the PageDown key).
