- """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, Grid and
- Place methods are redirected to the Frame widget however.
