title: Is there a way to add a QWidget to a QMenu in QtCreator
body: <p>I'm creating a text editor and I'd like to put the <code>QComboBox</code> in the <code>QMenu</code>. I didn't find any method inside the <code>QMenu</code> that handled such a thing. The closest is <code>QMenu::addAction()</code>. I was wondering of getting around this hurdle. </p>
  
  <p>Thanks!</p>
