Hi,
whenever I clicked the "save"-button in a plot in my TkAgg and pressed
"cancel" in the file dialog, I got the error message
Exception in Tkinter callback
Traceback (most recent call last):
File "lib-tk/Tkinter.py", line 1406, in __call__
return self.func(*args)
File
"/usr/lib/python2.5/site-packages/matplotlib/backends/backend_tkagg.py",
line 641, in save_figure
bname, fext = os.path.splitext(fname)
File "posixpath.py", line 92, in splitext
i = p.rfind('.')
AttributeError: 'tuple' object has no attribute 'rfind'
This obviously happened because tkFileDialog.asksaveasfilename returned
an empty tupel rather than an empty string, when the user cancels the
file dialog. I fixed it by replacing the line
if fname == "":
by
if fname == "" or fname == ():
in the file backend_tkagg.py.
Thank you,
Michael Zell
