set_enum

Looks up the enumerated type nick for value and writes it to key, within this.

It is a programmer error to give a key that isn't contained in the schema for this or is not marked as an enumerated type, or for value not to be a valid value for the named type.

After performing the write, accessing key directly with get_string will return the 'nick' associated with value.

Parameters:

this	a Settings object
key	a key, within this
value	an enumerated value

Returns:

true, if the set succeeds
