Interrupt is fixed

OK, my mistake. I'm using 1.1.1rc2.

I was using a new installation without any matplotlibrc, and was defaulted to
gtk.

If I set:
backend : Qt4Agg

then the problem has returned.

Presumably you mean on the qt4 backend? If so, glad to be of some help! :slight_smile:

The change came in in PR #851
(https://github.com/matplotlib/matplotlib/pull/851/files#diff-7) and
also allows you to close a figure with ctrl+w and make a qt4 figure
fullscreen with "ctrl+f" (actually, just "f" will do, but I have an
ambition to nuke the non-controled versions by default).

UPDATE: I've just noticed that your traceback is showing your backend
as gtk, for which I cannot take any credit (nor do I know the change
which caused this improvement).

One annoyance with mpl in the past is that when running a script, SIGINT
would not kill it (needed to use C-c C-\ instead).

It seems this is now fixed:

Interrupt now gives me:

  File "/home/nbecker/.local/lib/python2.7/site-
packages/matplotlib/backends/backend_gtk.py", line 77, in mainloop
    gtk.main()
KeyboardInterrupt

Usually, the source of such problems is someone using a bare try…except. KeyboardInterrupt subclasses BaseException. There is a subtle difference between

try:
foo()
except:
pass

and

try:
foo()
except Exception:
pass

The first will capture Ctrl-C and throw it away, while the latter will not. PEP8 recommends against blind usage of bare except clauses.

Happy hunting!

Ben, actually the PyQt4 backend is responsible for this (a hello world
pyqt4 application doesn't accept sigint). However, I have fixed master
(in the aforementioned PR) so that ctrl+c from the command line
actually closes the figure.

HTH,
