title: Qt 5.4 OS X how to use a QAction in both a QMenu and a QToolBar, but show the icon only in the QToolbar
body: <p>Using Qt 5.4 on OS X (Yosemite), I have a <code>QAction</code> that has an icon.  I want the icon to show in the <code>QToolbar</code> that I add the action to.  This works fine.  However, I do NOT want the icon to show in the QMenu that I add the action to.</p>
  
  <p>How do I do that?</p>
