Connecting to menubar created in designer qt4 from python

[rklein3013]

I created a menubar with an item - File / Exit. Now I would like to access them in my python code. Buttons are simple just type self.buttonB.clicked.connect(self.buttonB_clicked). How do I access the menubar File / Exit to then exit my program/gui
