matplotlib-devel Mailing List for matplotlib

"Birds of a Feather". It is a mini-session that can be held at the SciPy
conference that is going on right now in Austin. Like-minded people can
get together and discuss a particular topic (such as matplotlib) in a
face-to-face setting.
Cheers!

Ben and other matplotlib BoF folks,
As of this afternoon, there are new signup sheets on a stand near the top
of the stairs on the third floor. The sheets have rooms that are available
and time slots that you can pencil in to reserve for your group. Briefly,
there are four small rooms (6-8 people) available on the first floor: rooms
109, 110, 111 and 112. The lecture halls (the ballroom and room 106) are
also available after the conference talks are done at 6:30, and during the
lunch time.

Thanks for the notice. I have rescheduled for 8 PM in room 109 tonight.

Also, if desired, we could also set a different time.

technically, there is supposed to be a BOF about now, but I just realized
that no location was specified. We could meet in the atrium unless anyone
has a better idea.

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.

I'm afraid it's only an annoyance, and I doubt I'll be motivate to try to hunt 
that down.

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!

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! :-)
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
