The text widget and scrollbar are packed together in a :class:`Frame`, and the
methods of the :class:`Grid` and :class:`Pack` geometry managers are acquired
from the :class:`Frame` object. This allows the :class:`ScrolledText` widget to
design your application by choosing the most appropriate widgets to match the
special needs of your application and users.
