title: Extensible application using Qt
body: <p>I am working on an application which interact with a database and construct reports, I want this application to be extensible and I can in the future to integrate custom report builders to the application as plugins.</p>
  
  <p>I have some question about the plugin architecture supported by Qt:</p>
  
  <ul>
  <li><p>Can I load the plugins in there own processes ?</p></li>
  <li><p>How could I send some custom QML type from the plugin to main application and hook some event handlers on it. </p></li>
  </ul>
  
  <p>Another question: is there any framework to develop service based qt application ?</p>
