You might need to react to every change of selection in the ComboBox, for instance to update other widgets. To do so, you should handle the <code class="literal">changed</code> signal. For instance:
</p>
<pre class="programlisting">m_combo.signal_changed().connect( sigc::mem_fun(*this,
      &amp;ExampleWindow::on_combo_changed) );</pre>
