| 7 | # AutoScan -- |
| 8 | # This procedure is invoked when the mouse leaves an entry window |
| 9 | # with button 1 down. It scrolls the window up, down, left, or |
| 10 | # right, depending on where the mouse left the window, and reschedules |
| 11 | # itself as an "after" command so that the window continues to scroll until |
| 12 | # the mouse moves back into the window or the mouse button is released. |
| 13 | # |
| 14 | # Arguments: |
| 15 | # w - The entry window. |
| 16 | # x - The x-coordinate of the mouse when it left the window. |
| 17 | # y - The y-coordinate of the mouse when it left the window. |
