Frame widget (title and geometry)

[Shankar Iyer (siyer@Princeton.EDU)]

Hi,

      I am still new to Python and Tkinter, so I apologize in advance if I do not word my question optimally.  I am trying to use a frame widget as the parent for other widgets.  There is a class with the header "class classtitle(Frame):" in a script called classtitle.py.  Having imported classtitle, I create a Frame widget within my gui using the command "w = Frame(self)."  Then, I grid this widget and issue the command "classinstance = classtitle.classtitle(w)."  When I attempt to execute this code, I receive an error claiming that w lacks geometry and title attributes that the code in classtitle.py attempts to access.  Does this mean that I cannot use a Frame widget as w in this situation?  Thanks for your help.
