<hr><a name="_details"></a><h2>Detailed Description</h2>
Abstract base clase for <a class="el" href="classGtk_1_1HScale.html">Gtk::HScale</a> and <a class="el" href="classGtk_1_1VScale.html">Gtk::VScale</a>.
<p>
A Gtk::Scale is a slider control used to select a numeric value. To use it, you'll probably want to investigate the methods on its base class, <a class="el" href="classGtk_1_1Range.html">Gtk::Range</a>, in addition to the methods for Gtk::Scale itself. To set the value of a scale, you would normally use <a class="el" href="classGtk_1_1Range.html#a13">set_value()</a>. To detect changes to the value, you would normally use <a class="el" href="classGtk_1_1Range.html#a15">signal_value_changed()</a>.
<p>
The Gtk::Scale widget is an abstract class, used only for deriving the subclasses <a class="el" href="classGtk_1_1HScale.html">Gtk::HScale</a> and <a class="el" href="classGtk_1_1VScale.html">Gtk::VScale</a>, so you should instantiate them instead.
