You want to connect to Gtk::ComboDropDown::signal_select_child, ala

m_Combo.get_list()->signal_select_child().connect(sigc::mem_fun(*this,&ExampleWindow::on_child_selected));

Where &ExampleWindow::on_child_selected is prototyped:

   void on_child_selected(Gtk::Widget& child);

in your ExampleWindow class derivation.
