[PyQt] accessing and modifying a menubar

[lloyd konneker]

Your question is more generally about Qt and not specific to PyQt so you 
might get more answers on Qt Forums.

Is QtDesigner automatically creating the menubar or are you  doing it?  
(I am not that familiar with QtDesigner.)  In general, Qt strives hard 
to make the menubar in a mainwindow conform to OSX, so I would think it 
rare for you or QtDesigner to mock it up yourself.

If nothing else, you could use QObject.findChild() called on the 
mainwindow if you know the objectName property of the menubar.
