8.1 version

on-range-change

Arguments: dialog-item

Returns the value of the on-range-change event property of dialog-item. The value of the on-range-change property should be a function object or a function name (a symbol naming a function). This function is called when the range of dialog-item is changed. This function should accept three arguments, the dialog-item, the new range, and the old range. The value may be nil if no function need be called. (The function is not responsible for changing the range. It just provides a way for the application to do whatever it wishes when the range is changed.)

See cg-events.htm for information about event handling in Common Graphics.
