## Detailed Description

### template<typename R, typename P1, typename P2>
class Inti::G::Signal2< R, P1, P2 >

A template for a signal passing two arguments of type P1 and P2, and returning a value of type R.

## Constructor & Destructor Documentation

template<typename R, typename P1, typename P2>
Inti::G::Signal2< R, P1, P2 >::Signal2 | ( | const char * | name | ) | `[inline]`

Constructor.

Parameters:

  name | The GTK+ name for the signal.

## Member Function Documentation

template<typename R, typename P1, typename P2>
Connection Inti::G::Signal2< R, P1, P2 >::connect | ( | TypeInstance * | instance,
|  | const SlotType * | slot,
|  | bool | after = false
| ) | const`[inline]`

Connect a slot to the signal.

Parameters:

  instance | An object derived from G::TypeInstance.
  slot | A slot of type Slot2<R, P1, P2>.
  after | Set true to call the user-defined slot after the signal, or false to let the signal's default behavior preside.

Returns:
  A connection object.

The connection object can be used to control the signal connection, either by calling block(), unblock() or disconnect(). You don't need to call discconnect() unless you have good reason to. GTK+ signals are automatically disconnected when an object gets destroyed.
