Maybe Francisco meant the following:
>>> l = Label(text='foo')
>>> l.pack()
>>> l.config(font='Helvetica 12')
this works, but:
>>> l.config(font='Bitstream Vera Sans 12')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.6/lib-tk/Tkinter.py", line 1205, in configure
return self._configure('configure', cnf, kw)
File "/usr/lib/python2.6/lib-tk/Tkinter.py", line 1196, in _configure
self.tk.call(_flatten((self._w, cmd)) + self._options(cnf))
_tkinter.TclError: expected integer but got "Vera"
I think the Tkinter equivalent to tcl's list command in this context is
to simply pass a sequence instead of a string to the font option:
>>> l.config(font=('Bitstream Vera Sans', '12'))
>>>
just like one would do in other cases where Tk expects a list, as e.g.
canvas coords.
Best regards
Michael
