Depends.
If you need the event object (i.e. the data it contains, like
event.widget, etc.) then you need to pass it in as you wrote.
However, it is not mandatory. If CommonHandler looks like:
def Commonhandler(arg):
print arg
# or popup a modal dialog asking wheter the user wants to quit
# i.e. doing something for which event data is not needed
then its not needed.
(I assumed you didnt want to change CommonHandler : ) )
