## 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.)
