* If the function returns %FALSE, it usually means that the value is

* not a valid choice in current situation. In this case, you might want
|
|
* to toggle instead another value automatically. Set @new_value to the
|

* value to toggle. If you leave this untouched, the radio button will

* stay toggled despite being insensitive. This is up to you to decide
