Re: [Matplotlib-users] 'save file' GUI dialog

[Chris B. <bea...@ha...>]

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... :)
