[Matplotlib-users] modifying the toolbar?

[C M <cmp...@gm...>]

Hi, I have just begun including the toolbar in an embedded (in wx)
use of mpl, and am really pleased with how easily it provides very
useful functions.  Once again, mpl shines.

But I would like to try to modify the toolbar for my application, e.g.
probably remove the "configure subplots" tool (n/a in my context)
and in fact add a number of my own application-specific tools to
that same toolbar.

I  didn't see any toolbar class within the widgets.py file in the
matplotlib directory.  So, a) where can I find it, and b) is there
anything I should be aware of regarding modifying the toolbar?

Thanks,
Che
