Eric: in Shell,py, around line 1167, you'll find this code:
backends = {'gthread' : 'GTKAgg',
'wthread' : 'WXAgg',
'qthread' : 'QtAgg',
'q4thread' :'Qt4Agg',
'tkthread' :'TkAgg',
}
That is used to SET the rcParams['backend'] value. I don't know if
that can cause issues.
But more importantly, I think the problem you see comes from this code
(just a bit later in the same file):
else:
backend = matplotlib.rcParams['backend']
if backend.startswith('GTK'):
th_mode = 'gthread'
elif backend.startswith('WX'):
th_mode = 'wthread'
elif backend.startswith('Qt4'):
th_mode = 'q4thread'
elif backend.startswith('Qt'):
th_mode = 'qthread'
else:
# Any other backend, use plain Tk
th_mode = 'tkthread'
return mpl_shell[th_mode]
IPython does an explicit check on the names of the backends with that
exact capitalization. I could add a .lower() call to the line that
starts:
backend = matplotlib.rcParams['backend'].lower()
and change the .startswith() calls to do all lowercase checks. Could
you see if that helps? That would make the fix backwards compatible.
Cheers,
