<hr><a name="_details"></a><h2>Detailed Description</h2>
A GtkScale C++ wrapper class. 
<p>
The <a class="el" href="classGFC_1_1Gtk_1_1Scale.html">Scale</a> widget is an abstract class, used only for deriving the subclasses <a class="el" href="classGFC_1_1Gtk_1_1HScale.html">HScale</a> and <a class="el" href="classGFC_1_1Gtk_1_1VScale.html">VScale</a>.<p>
A <a class="el" href="classGFC_1_1Gtk_1_1Scale.html">Scale</a> 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="classGFC_1_1Gtk_1_1Range.html">Range</a>, in addition to the methods for <a class="el" href="classGFC_1_1Gtk_1_1Scale.html">Scale</a> itself. To set the value of a scale, you would normally use <a class="el" href="classGFC_1_1Gtk_1_1Range.html#z738_6">Gtk::Range::set_value()</a>. To detect changes to the value, you would normally connect to the <em>value_changed</em> signal.
