Changing the list of values of an option menu at runtime

[Giulio Mastrosanti]

I'm looking at the list of properties of a button that has 'option' as
style, but i can't find the list of values it can have (the list i write on
the property stack on the field "Create button menu with contents:")

So i can't figure how can I read the values or change them on the fly, for
example using values from a database table

Any idea?

Regards,
