title: How to create a Gtk combobox with the interface new_with_area?
body: <p>According to the gtk documentation you can create a combobox with:</p>
  
  <pre><code>GtkWidget * gtk_combo_box_new ()
  GtkWidget * gtk_combo_box_new_with_entry ()
  GtkWidget * gtk_combo_box_new_with_model ()
  GtkWidget * gtk_combo_box_new_with_model_and_entry ()
  GtkWidget * gtk_combo_box_new_with_area ()
  GtkWidget * gtk_combo_box_new_with_area_and_entry ()
  </code></pre>
  
  <p>I have found a lot of examples for the <code>gtk_combo_box_new_with_model</code> but I can't find anything related to the use of <code>gtk_combo_box_new_with_area</code> .</p>
  
  <p>The langage used doesn't matter.</p>
