[Pyobjc-dev] HelloWorld.py (demo code)

[Steven D. M. <sd...@mi...>]

# HelloWorld.py
#
# You have to run this script from the command line with
# the full pathname for python:
#    /usr/local/bin/python HelloWorld.py
#
# or else run from DropShell or gdb. Anything else and you will get a:
#       Error 1011 in _sendFinishLaunchingNotification
# and it wont work.
