1475      1) If the window has a QMenuBar then it is used. 2) If the window
1476      is a modal then its menubar is used. If no menubar is specified
1477      then a default menubar is used (as documented below) 3) If the
1478      window has no parent then the default menubar is used (as
1479      documented below).
1480
1481      The above 3 steps are applied all the way up the parent window
1482      chain until one of the above are satisifed. If all else fails a
1483      default menubar will be created, the default menubar on Qt/Mac is
1484      an empty menubar, however you can create a different default
1485      menubar by creating a parentless QMenuBar, the first one created
1486      will thus be designated the default menubar, and will be used
1487      whenever a default menubar is needed.
1488
1489   Thus, for Qt/Mac, we add the menus to a free standing menubar, so
1490   that this menubar will be used also when one of LyX' dialogs has
1491   focus. (JMarc)
