- # A ScrolledText widget feels like a text widget but also has a
- # vertical scroll bar on its right. (Later, options may be added to
- # add a horizontal bar as well, to make the bars disappear
- # automatically when not needed, to move them to the other side of the
- # window, etc.)
- #
- # Configuration options are passed to the Text widget.
- # A Frame widget is inserted between the master and the text, to hold
- # the Scrollbar widget.
- # Most methods calls are inherited from the Text widget; Pack methods
- # are redirected to the Frame widget however.
