Hey Tom,
It looks like the only backend-agnostic file save function is save_figure()
(a toolbar method), which conflates choosing a filename and doing the
actual saving. The backend-specific code to choose a filename via a dialog
isn't uniform:
Qt4:
matplotlib.backends.backend_qt4._getSaveFileName
MacOS
matplotlib.backends.backend_osx._macosx.choose_save_file
Wx:
A bunch of code in matplotlib.backends.backend_wx.save_figure
TkAgg:
Tkinter.FileDialog
GtkAgg:
get_filechooser().get_filename_from_user()
It looks like, at a minimum, you would have to write your own wrapper code
to make a backend-agnostic interface for choosing a filename. Of course, if
you did that, it would also be nice to refactor that into MPL itself... :)

Hi everyone,
I'm developing a simple GUI tool in Matplotlib that relies on the
event framework to handle buttons/sliders. I am trying to avoid using
a GUI toolkit directly to ensure maximum compatibility for users.
One thing I would like is to be able to have a 'save' button that will
open up a standard 'save file' dialog window (but not necessarily the
plot itself). Matplotlib already has 'save file' GUI dialogs for the
different backends, so I was wondering whether there is an easy and
abstract way of asking matplotlib to open a 'save file' dialog and
capturing the output? Or is this all handled separately in the
different backends?
Thanks!
Tom
