Connect a slot to the signal.
- Parameters
-
slot - a slot of type Slot2<R, P1, P2>.
- Returns
- a connection object.
The returned connection object can be used alter or change the connection.
Referenced by scim::Signal2< void, P1, P2, IgnoreMarshal >::connect().
|
inline |
Returns a slot for this signal.
- Returns
- a new slot of type Slot2<R, P1, P2>.
The returned slot can be passed to another signal allowing the other signal to call this signal when it gets emitted.
Referenced by scim::Signal2< R, P1, P2, Marshal >::emit(), and scim::Signal2< void, P1, P2, IgnoreMarshal >::emit().
|
inline |
Emit the signal.
- Parameters
-
p1 - passes p1 to the signal handler. p2 - passes p2 to the signal handler.
- Returns
- the value returned by the signal handler.
Calls every slot connected to this signal, in order of connection.
