Key Press event is captured by the Window, not just the plot area.

At creation time of the canvas:

self.canvas.set_can_focus(True)

And in "on_click" handler (or wherever/whenever desired):

self.canvas.grab_focus()

Then the key event will be handled appropriately with either connect() or mpl_connect(). This was simpler than what is described for C.

Could be desirable to also handle the focus_in/focus_out to show in the GUI that the drawing area has the focus:

 self.canvas.connect('focus_in_event', on_focus_in)
 self.canvas.connect('focus_out_event', on_focus_out)
