| 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 List widget. |
| 8 | # A Frame widget is inserted between the master and the list, to hold |
| 9 | # the Scrollbar widget. |
| 10 | # Most methods calls are inherited from the List widget; Pack methods |
| 11 | # are redirected to the Frame widget however. |
