咆哮Python綁定點擊反饋？

Question

我正在嘗試使用Growl Python綁定（來自Growl存儲庫的Growl.py v0.7）來編寫一個小應用程序。目前缺少的功能之一是發送給Python的點擊通知。

我知道在Objective-C中，當用戶點擊通知時，它會向正在運行的應用程序發送一個觸發器。我想用Python綁定來做類似的事情。當用戶點擊通知時，我想讓Python程序在瀏覽器中打開一個URL（或以其他方式處理事件）。

關於我如何實現它的任何想法？

更新：感謝synthesizerpatel誰提供了一個有前途的解決方案，我把他的話在獅子工作。不幸的是，我開始淡出Mac，所以我不再做Mac編程了。雖然，我做了一些調試，因爲它仍然不是雪豹工作，並在這裏就是爲什麼：

Discussion Growl PyObjC not working with PyObjC 2.2b3

這是你想要的嗎？

#!/usr/bin/env python

# pyGrr! 
# 
# 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
