Growl Python 与点击反馈绑定？

Question

我正在尝试使用 Growl Python 绑定（来自 Growl 存储库的 Growl.py v0.7）来编写一个小型应用程序。当前缺少的功能之一是发送到 Python 的点击通知。

我知道在 Objective-C 中，当用户单击通知时，它会向正在运行的应用程序发送触发器。我想对 Python 绑定做类似的事情。当用户单击通知时，我想让 Python 程序在浏览器中打开 URL（或以其他方式处理事件）。

关于我如何实现它有什么想法吗？

更新：感谢synthesizerpatel提供了一个有前途的解决方案，我相信他的话，它在Lion上有效。不幸的是，我开始淡出 Mac，所以我不再做太多 Mac 编程了。不过，我做了一些调试，因为它仍然无法在 Snow Leopard 上运行，原因如下：

# 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
