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()
