init(self, grammar, tokens, title=`'Chart Parser Application'`)
(Constructor)

Overrides: object.__init__: (inherited documentation)

mainloop(self, *args, **kwargs)

Enter the Tkinter mainloop. This function must be called if this demo is created from a non-interactive program (e.g. from a secript); otherwise, the demo will close as soon as the script completes.
