My Mac is currently dead, but I developed these events while I was a
mac user and so am pretty sure they worked. It is more likely a
specific backend problem than a Mac vs non-Mac problem (eg it may be
specific to the macosx backend but not a problem for macs in general)
http://matplotlib.sourceforge.net/faq/installing_faq.html#what-is-a-backend
Could you try running the script with the "use" directive at the top
of your script (before any other mpl code) for different backends, eg
tkagg vs macosx vs wxagg
import matplotlib
matplotlib.use('tkagg') # and also try macosx and wxagg
so we can see exactly where the problem is arising. Also, run your
script with --verbose-helpful and report the debugging output.
Looking at the code, it appears the enter_notify_event and
leave_notify_event are only defined for wx, qt and gtk currently, and
so need to be implemented for tk and macosx.

I almost have a solution for this for the Mac OS X backend. I am stuck though at what I should pass to enter_notify_event and leave_notify_event for the guiEvent:
def leave_notify_event(self, guiEvent=None):
"""
Backend derived classes should call this function when leaving
canvas
*guiEvent*
the native UI event that generated the mpl event
"""
What are the requirements for guiEvent? If I call leave_notify_event without guiEvent, so guiEvent = None, then the example gives me the following error:
enter_figure Figure(640x480)
leave_figure
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/backend_bases.py", line 1416, in leave_notify_event
self.callbacks.process('figure_leave_event', LocationEvent.lastevent)
File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/cbook.py", line 169, in process
func(*args, **kwargs)
File "test.py", line 23, in leave_figure
print 'leave_figure', event.canvas.figure
AttributeError: 'NoneType' object has no attribute 'canvas'
So I guess I should pass some type of event object to enter|leave_notify_event.

we don't make any assumptions about what kind of object the gui event
is. We provide the GUI event because sometimes when using a specific
backend, the user wants to drill into the GUI native event (eg a
button press event) but we don't use it anywhere in the mpl frontend
because this would break the abstraction. So if you have some event
that is being fired at the UI level on figure enter, pass that in.
It looks like you may be having a problem because the
leave_notify_event is getting called more than once, or is called for
a figure that has not been entered. Check the logic in
backend_bases.FigureCanvasBase.leave_notify_event
def leave_notify_event(self, guiEvent=None):
"""
Backend derived classes should call this function when leaving
canvas
*guiEvent*
the native UI event that generated the mpl event
"""
self.callbacks.process('figure_leave_event', LocationEvent.lastevent)
LocationEvent.lastevent = None
It looks like your figure_leave_event is being triggered with
LocationEvent.lastevent = None (so it is not a problem with your
guiEvent). This could happen if a leave event was processed *before*
and enter event (which sets the lastevent), or if a leave event was
processed twice.
Hopefully this will help you drill down into the source of the problem
