<hr><a name="_details"></a><h2>Detailed Description</h2>
A GtkScrollbar C++ wrapper class.
<p>
The <a class="el" href="classGFC_1_1Gtk_1_1Scrollbar.html">Scrollbar</a> widget is an abstract base class for <a class="el" href="classGFC_1_1Gtk_1_1HScrollbar.html">HScrollbar</a> and <a class="el" href="classGFC_1_1Gtk_1_1VScrollbar.html">VScrollbar</a>. It is not very useful in itself. The position of the thumb in a scrollbar is controlled by the scroll adjustments. See <a class="el" href="classGFC_1_1Gtk_1_1Adjustment.html">Adjustment</a> for the fields in an adjustment - for <a class="el" href="classGFC_1_1Gtk_1_1Scrollbar.html">Scrollbar</a>, the "value" field represents the position of the scrollbar, which must be between the <em>lower</em> field and <em>upper - page_size</em>. The <em>page_size</em> field represents the size of the visible scrollable area. The <em>step_increment</em> and <em>page_increment</em> fields are used when the user asks to step down (using the small stepper arrows) or page down (using for example the Page Down key).
