title: Why doesn't my combobox display text?
body: <p>I'am working in a GTK-sharp application. I have this code but <code>combobox1</code> doesn't display any item. Why not?</p>
  
  <pre><code>ListStore store = new ListStore(typeof(myclass));
  
  store.AppendValue(new myclass("hola",7));
  store.AppendValue(new myclass("hola2",8));
  store.AppendValue(new myclass("hola3",2));
  
  combobox1.Model = store;
  </code></pre>
  
  <p>The class <code>myclass</code> overrides <code>ToString()</code></p>
