title: Serialization QList<MyObject> to JSON
body: <p>I've problem, I tried searched online like convert <code>QList</code> to JSON, and send it to URL, but first, I don't found nothing about serialise <code>QList&lt;Myobject&gt;</code> to json with Qt and C++.</p>
  
  <p>My not empty <code>QList</code>: </p>
  
  <pre><code>QList&lt;User&gt; lista;
  </code></pre>
  
  <p>my target is lista to JSON.</p>
  
  <p>How to serialize it? I've saw online that <code>QJson</code> exists, but is an external compenent... there is a internal component within Qt 5.9?</p>
