Re: [Matplotlib-users] Trouble embedding toolbar in Tk using grid

[Jonno <jon...@gm...>]

Well I realized my error with the extra window being caused by the
TopLevel() command. I switched this to Tk.Tk() and it works nicely.
However I still have to pack the frame instead of using grid. I can
work around this but I wonder if there isn't something else I'm
missing.
