---|
357 | ; handler routine. |

358 | ; VALUE returns the new value of the slider. |

359 | ; DRAG returns integer 1 if the slider event was generated as part of |
---|
360 | ; a drag operation, or zero if the event was generated when the user |
---|
361 | ; had finished positioning the slider. Note that the slider widget |
---|
362 | ; only generates events during the drag operation if the DRAG keyword |
---|
363 | ; is set, and if the application is running under Motif. When the |
---|
364 | ; DRAG keyword is set, the DRAG field can be used to avoid |
