>>> from Tkinter import * >>> import Pmw >>> master = Tk() >>> g = Pmw.Blt.Graph( master ) I got the following error message after I typed the last line: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "C:\Python26\lib\site-packages\Pmw\Pmw_1_3\lib\PmwBlt.py", line 260, in _ _init__ Tkinter.Widget.__init__(self, master, _graphCommand, cnf, kw) File "C:\Python26\lib\lib-tk\Tkinter.py", line 1932, in __init__ (widgetName, self._w) + extra + self._options(cnf)) _tkinter.TclError: invalid command name "::blt::graph I am a newbie in python. Does anybody know what causes this error? I am running python 2.6.3 under windows xp. Thanks for your help!!
