1 # A ScrolledText widget feels like a text widget but also has a

     2 # vertical scroll bar on its right.  (Later, options may be added to

     3 # add a horizontal bar as well, to make the bars disappear

     4 # automatically when not needed, to move them to the other side of the

     5 # window, etc.)

     6 #

     7 # Configuration options are passed to the Text widget.

     8 # A Frame widget is inserted between the master and the text, to hold

     9 # the Scrollbar widget.

    10 # Most methods calls are inherited from the Text widget; Pack methods

    11 # are redirected to the Frame widget however.
