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.)
