我正在尝试使用Growl Python绑定（来自Growl存储库的Growl.py v0.7）来编写一个小应用程序。目前缺少的一个功能是发送给Python的点击通知。
我知道在Objective-C中，当用户点击通知时，它会向正在运行的应用程序发送一个触发器。我想用Python绑定做类似的事情。当用户点击通知时，我想让Python程序在浏览器中打开一个URL（或以另一种方式处理事件）。
关于如何实现它的任何想法？
更新：感谢合成器配件提供了一个很有前途的解决方案，我认为它适用于Lion。不幸的是，我开始从Mac淡出，所以我不再做很多Mac编程了。虽然，我做了一些调试，因为它仍然没有在Snow Leopard上工作，这就是为什么：

# This code was originally found @
# http://www.cocoaforge.com/viewtopic.php?f=6&t=13359&p=91992&hilit=pyobjc+growl
# It is (to the best of our knowledge) the work of user 'tooru' on the same
# website.
#
# I make no claim to this code, all I did was get it working with PyObjC on Lion
# reformatted it a bit and added some more verbose explanations of what the script
# does. To be honest, I haven't touched pyobjc in a couple years and I was amazed
# that it still works! Even more amazed that I was able to get this example working
# in about 20 minutes.
#
# Great job tooru!
#
# I have verified this code works with the following combination of
# packages / versions
#
# * OSX Lion 10.7.3
# * Python 2.7
# * Growl 1.3
# * Growl SDK 1.3.1
