title: QVariantList append
body: <p>I tri to append a QVariant to another QVariant (which must be a QVariantList).</p>
  
  <blockquote>
  <pre><code>QList&lt;int&gt; listInt;
  listInt.append(1);    
  QVariant v;
  v.setValue(listInt);
  if(v.canConvert(QVariant::List))
  {
      QVariant v1;
      v1.setValue(5);
      qvariant_cast&lt;QVariantList&gt;(v).append(v1);
  }
  objC.setProperty("_list", v);
  </code></pre>
  </blockquote>
  
  <p>But in the <code>obC</code> my <code>_list</code> contains only the integer 1.
  What is the problem?</p>
