NavigationToolbar2TkAgg changes in v1.2.0 win32 py2.6?

Ah ok that makes more sense, thanks!

So the change was made in
c887139224
“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.
