The value is an arbitrary integer which can be used as a
convenient way to determine which action in the group is
currently active in an ::activate or ::changed signal handler.

The ::changed signal is emitted on every member of a radio group when the
active member is changed. The signal gets emitted after the ::activate signals
for the previous and current active members.
