I went ahead an implemented the close events. These work for me on the
following backends that I was able to test: TkAgg, Wx/WxAgg, Qt4Agg,
Gtk/GtkAgg.
I can't test Cocoa or PyQt3, so I didn't implement. All that is needed
is to add a call (preferably on a FigureCanvasBase subclass) that
calls the FigureCanvasBase.close_event().

Update:
I just tried "make -f make.osx fetch deps mpl_install", which gave me the following results:

First the easy one:
When I click on the link for the archives on the matplotlib page:
http://www.nabble.com/matplotlib---users-f2906.html
I get sent to this page:
http://www.nabble.com/-td2885.html#a2906
which is in some Slavic looking language, so I can't tell what it's a forum for, but it's probably not matplotlib.
Anyway.
My _real_ question is about building from svn on OS X.
(Before anyone asks me _why_ I'm building on OS X, it's because there is a PDF bug in the current released version which I need to avoid).
There are instructions to modify make.osx to include a local directory where dependencies are downloaded, which I did. There aren't any further instructions, however, so I've building/installing using setup.py, which runs, but has a run-time error regarding free-type fonts that I have encountered before. I've also tried running make with various arguments, none of which appear to do anything useful.
What are the proper build/install commands for OS X once the make.osx file has been edited?
Thanks,
Mike

Hello.
I would like to know how to find informations about how pyplot, imshow
and contourf, contour functions are working.
I'm looking for a way to derive/improve this functions because I dont
know how to make my plot properly otherly.
Thank you very much.
Greetings,
David Kremer

First of all, thanks, klukas for the useful piece of code.

Well, I guess BrokenAxes.plot should return a list of lines instead of a
line in ll.
i.e. something like "[[x.lines[-1] for x in ax.subaxes]]"
would replace "[ax.lines[-1]]" as the return value.
Better yet, instead of a list we should have a "vector-type" proxy
container that should transfer method calls to the contained items.

Ideally this should really be one artist.
However from JDH's response I understand this would be harder to
implement (using custom transforms or something). Maybe emulating one
using the current implementation (as I suggested above) is good enough.
Meanwhile, this redundant looping for each plot call is annoying, so I
can offer the following compromise: store the subaxes in the parent
(broken)Axes (add "self._subaxes = subaxes" before returning from breakx
and breaky), then add a new plot_subs method:
def plot_subs(self,*args,**keys):
 for sub in self._subaxes:
 res = sub.plot(*args,**keys)
 return res
This is a simplified version, returning just the lines of the last
subaxes, but at least this way you can avoid the looping.
