If TextWidgetsFrame inherets from frame, you can override the destroy() 
method which gets called when the parent gets destroyed. Or 
alternatively, you can override the __del__ function, which gets called 
when the reference count goes to 0:


py> from Tkinter import *
py> tk = Tk()
py> class F(Frame):
...   def destroy(self):
...     print 'bob'
...     Frame.destroy(self)
...
py> f = F(tk)
py> f.pack()
py> tk.destroy()
bob
