title: Use signals or Q_PROPERTY to update QML objects
body: <p>I'm very frequently receiving data from a server. This data is mainly composed of numbers. Each of them is corresponding to a QML object that would need to be updated.</p>
  
  <p>What would be the best course of action between <code>Q_PROPERTY</code> and <code>signals</code> in order to update the <code>QML</code> objects from the <code>C++</code> files?</p>
