title: Setting Mac OSX Application Menu menu bar item to other than "Python" in my python Qt application
body: <p>I am writing a GUI application using python and Qt.  When I launch my application on Mac, the first menu item in the Mac menu bar at the top of the screen is "Python".  I would prefer the application name there to be the name of my application.  How can I get my program name up there?</p>
  
  <p>The following demo program creates a window with two menus: "Python", and "Foo".  I don't like that, because it makes no difference to my users whether I wrote the app in python or COBOL.  Instead I want menus "MyApp" and "Foo".</p>
  
  <pre><code>#!/usr/bin/python
  
  # This example demonstrates unwanted "Python"
  # application menu name on Mac.
  
  # Makes no difference whether we use PySide or PyQt4
  from PySide.QtGui import *
  # from PyQt4.QtGui import *
  
  import sys
  
  app = QApplication(sys.argv)
  # Mac menubar application menu is always "Python".
  # I want "DesiredAppTitle" instead.
  # setApplicationName() does not affect Mac menu bar.
  app.setApplicationName("DesiredAppTitle")
  win = QMainWindow()
  # need None parent for menubar on Mac to get custom menus at all
  mbar = QMenuBar()
  # Add a custom menu to menubar.
  fooMenu = QMenu(mbar)
  fooMenu.setTitle("Foo")
  mbar.addAction(fooMenu.menuAction())
  win.setMenuBar(mbar)
  win.show()
  sys.exit(app.exec_())
  </code></pre>
  
  <p>How can I change that application menu name on Mac?  EDIT: I would prefer to continue to use the system python (or whatever python is on the user PATH) if possible.</p>
