title: How to display a QDate-month with a different locale than system?
body: <p>The function <a href="http://doc.qt.io/qt-5/qdate.html#toString" rel="nofollow noreferrer"><code>QDate::toString(const QString &amp;format)</code></a> allows to display the month name with <code>MMM</code> (e.g. 'Jan' to 'Dec') or <code>MMMM</code> (e.g. 'January' to 'December').</p>
  
  <p>But this function uses the system locale from <code>QLocale::system()</code> (<a href="https://code.woboq.org/qt5/qtbase/src/corelib/tools/qdatetime.cpp.html#_ZNK5QDate8toStringE11QStringView" rel="nofollow noreferrer">source code</a>).</p>
  
  <p>What is the easiest way to display a <code>QDate</code> with a month name, for a specific QLocale ?</p>
