"""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.
