Values
Deferred
Connects a signal in deferred mode. This way, signal emissions are stored in a queue, then set on idle time.
Persist
Persisting connections are saved when the object is serialized to file.
Oneshot
One-shot connections disconnect themselves after emission.
ReferenceCounted
Connect a signal as reference-counted. This means that a given signal can be connected several times to the same target, and will only be fully disconnected once no references are left.
