title: Translate Qt QML application on the fly
body: <p>I'm trying to translate a qt QML application that is filled with </p>
  
  <pre><code>tr("string");
  </code></pre>

The only solution seems to be the <a href="https://wiki.qt.io/How_to_do_dynamic_translation_in_QML" rel="nofollow noreferrer" title="empty string hack">empty string hack</a> but I dont want to search for every "tr" and add the empty string </p>
