title: clicked() Signal for QListView
body: <p>I have a ListView and when I click in a row I need show more information about this row.
  My problem is that the signal clicked() does not work for ListView.
  When I initialize my application I get the following output in console</p>
  <blockquote>
  <p>Object::connect: No such signal QListView::clicked(index)</p>
  <p>Object::connect:  (sender name:   'appointments_list')</p>
  </blockquote>
  <p>And when I click in a row nothing happend.</p>
  <pre><code>class GUICustomerAppointmentDetail &lt; Qt::Widget
  
      def initialize (parent = nil, customer = nil)
          super(parent)
          ...     
          @ui.appointments_list.connect(SIGNAL('clicked(index)'), self, SLOT('load_data()')) 
      end
  
  end
  </code></pre>
  <p>appointments_list is a Qt::ListView</p>
  <p>I have replaced</p>
  <blockquote>
  <p>@ui.appointments_list.connect(SIGNAL('clicked(index)'), self,
  SLOT('load_data()'))</p>
  </blockquote>
  <p>by</p>
  <blockquote>
  <p>connect(appointments_list.connect, SIGNAL('clicked(index)'), self,
  SLOT('load_data()'))</p>
  </blockquote>
  <p>and I get</p>
  <blockquote>
  <p>Object::connect: No such signal QListView::clicked(index)</p>
  <p>Object::connect:  (sender name:   'appointments_list')</p>
  <p>Object::connect:  (receiver name: 'customerAppointmentDetail')</p>
  </blockquote>
  <p>also</p>
  <blockquote>
  <p>@ui.appointments_list.connect(SIGNAL('clicked(index)')){ load_data() }</p>
  </blockquote>
  <p>and I get</p>
  <blockquote>
  <p>Object::connect: No such signal QListView::clicked(index)</p>
  <p>Object::connect:  (sender name:   'appointments_list')</p>
  </blockquote>
  <p>Please, can anyone help me?</p>
