matplotlib-devel Mailing List for matplotlib

Ah ok that makes more sense, thanks!
So the change was made in c887139224<https://github.com/matplotlib/matplotlib/commit/c887139224ac30ceb2c77d249acf80da8ac9713e> "Backend factorisation for tooltip sharing".
Is there a reason backends can't provide access to the buttons from the toolbar object somehow though? The use-case is that GUIs using the Figure window can modify the buttons actions, e.g. to have the "save" button save various versions of a plot.
I don't think the means needs to be back-end agnostic, if you're mucking about with GUIs you've already accepted you are tied to a particular one.

Hi, I'm wondering if there's something wrong with the source included in the v1.2.0 win32 py2.6 exe? However I suspect I may have misunderstood something w.r.t svn.
The short version is that some code using the TkAgg backend which used self.figure.canvas.manager.toolbar.bsave stopped working when I upgraded from v1.1.
When I look in the svn browser here<http://matplotlib.svn.sourceforge.net/viewvc/matplotlib/trunk/matplotlib/lib/matplotlib/backends/backend_tkagg.py?annotate=8989> (which I assume is the current code?) I can see that in class NavigationToolbar2TkAgg, _init_toolbar() does create self.bsave etc.
However in the source I have from the download here<https://downloads.sourceforge.net/project/matplotlib/matplotlib/matplotlib-1.2.0/matplotlib-1.2.0.win32-py2.6.exe>, _init_toolbar() is a lot shorter and doesn't store the buttons as instance attributes.
Have I got confused or is something out of sync?
Thanks
Steve
