In matplotlib using the tkagg backend, the tk mainloop is started at the end of a python script by issuing a call to a "show" function, which realizes all the created figure windows and the calls Tkinter.mainloop(). This can cause problems if the mainloop was started by another module (eg idle).
Is there a way to query tkinter to detect whether the mainloop has already been called? Thanks, JDH -- http://mail.python.org/mailman/listinfo/python-list
