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.
