It's easy enough, using Menubutton and Menu, to make a menu pop up in
response to the user clicking a button. I want to make a menu pop up
when the user right-clicks on a canvas. This seems like a kind of common
thing to want to do but nothing in Tkinter or PMW is popping off the
page at me as a way to do this.
Am I just being really dense or is there no simple way to accomplish this?
