Description
If enabled, this event is generated when the user clicks one of the spin buttons in a Spinner object. The event is reported after the value of the Thumb property has been updated but before the Text property has been changed. You may use this event to set the text in the Spinner dynamically instead of relying on it being updated automatically.
The event message reported as the result of ⎕DQ, or supplied as the right argument to your callback function, is a 4-element vector as follows :
| [1] | Object | ref or character vector |
| [2] | Event | 'SetSpinnerText' or 421 |
| [3] | Thumb value | Integer. The new value of the Thumb property resulting from the user pressing one of the spin buttons. |
| [4] | Text | The text that is about to be put into the edit field. |
The SetSpinnerText event is designed to allow you to dynamically set the text in the Spinner in response to a spin button. It might be used in circumstances where the set of items you wish to present to your user is not predictable in advance.
