How to correctly construct a main menu in PyObjC?

Question

I am programmatically creating a menu in PyObjC with this hierarchy.

NSMenu (setMainMenu on NSApplication)
- NSMenuItem(1)
  - NSMenu: "App Name"
    - NSMenuItem(1)
    - NSMenuItem(2)
    ...
- NSMenuItem(2)
  - NSMenu: "File"
    - NSMenuItem(1)
    - NSMenuItem(2)
    ...
- NSMenuItem(3)
  - NSMenu: "Edit"
    - NSMenuItem(1)
    - NSMenuItem(2)
    ...
...

However, all PyObjC app shows is a single "Python" menu, that contains items that ought to be under "App Name".

How do I make it behave?

Answer 1

The "Python" menu is likely the menu from the MainMenu.nib in the Python.app application hidden in Python.framework. That application makes it possible to use GUI APIs in a command-line script without having to resort to private APIs.

The best way to get the proper behavior is to create an application bundle, either through py2app or manually.
