title: Qt5 with MacOS : How to add entries in the application menu?
body: <p>I'm writing an app using Qt5. That app runs on Window, Linux and now on MacOS.</p>
  
  <p>In order to make sure my app meets the apple's requirements, I would like to add entries in the application menu (preferences, about...).</p>

  <p>Does anyone know how to do so ?</p>
  
  <p>An <a href="http://qt-project.org/doc/qt-4.8/mac-differences.html" rel="nofollow noreferrer">old doc about Qt4.8</a> describes that the menu is handle by Qt but it doesn't describe what to do.</p>
