A template for a signal passing three arguments of type P1, P2 and P3, and returning a value of type R.
Member Typedef Documentation
◆ SlotType
| typedef Slot3<R, P1, P2, P3> scim::Signal3< R, P1, P2, P3, Marshal >::SlotType |
Function signature for handlers connecting to the signal.
Member Function Documentation
◆ connect()
|
inline |
Connect a slot to the signal.
- Parameters
-
slot - a slot of type Slot3<R, P1, P2, P3>.
- Returns
- a connection object.
The returned connection object can be used alter or change the connection.
References scim::Signal::connect(), and scim::Signal3< R, P1, P2, P3, Marshal >::slot().
◆ slot()
|
inline |
Returns a slot for this signal.
- Returns
- a new slot of type Slot3<R, P1, P2, P3>.
The returned slot can be passed to another signal allowing the other signal to call this signal when it gets emitted.

◆ emit()
|
inline |
Emit the signal.
- Parameters
-
p1 - passes p1 to the signal handler. p2 - passes p2 to the signal handler. p3 - passes p3 to the signal handler.
- Returns
- the value returned by the signal handler.
Calls every slot connected to this signal, in order of connection.
