## Detailed Description

### template<class R, class... T>
class Glib::SignalProxyDetailedAnyType< R, T >

Proxy for signals with any number of arguments and possibly a detailed name.

Use the connect() or connect_notify() method, with sigc::mem_fun() or sigc::ptr_fun() to connect signal handlers to signals.

## Member Function Documentation

## connect() [1/2]

template <class R , class... T>

sigc::connection Glib::SignalProxyDetailedAnyType< R, T >::connect | ( | const SlotType& | slot,
|  | bool | after = `true`
| ) |  |

inline

Connects a signal handler to a signal.

For instance, connect( sigc::mem_fun(*this, &TheClass::on_something) );

Parameters

  slot | The signal handler, usually created with sigc::mem_fun() or sigc::ptr_fun().
  after | Whether this signal handler should be called before or after the default signal handler.

## connect() [2/2]

template <class R , class... T>

sigc::connection Glib::SignalProxyDetailedAnyType< R, T >::connect | ( | SlotType&& | slot,
|  | bool | after = `true`
| ) |  |

inline

Connects a signal handler to a signal.

See also
  connect(const SlotType& slot, bool after).

Since glibmm 2.48:

## connect_notify() [1/2]

template <class R , class... T>

sigc::connection Glib::SignalProxyDetailedAnyType< R, T >::connect_notify | ( | const VoidSlotType& | slot,
|  | bool | after = `false`
| ) |  |

inline

Connects a signal handler without a return value to a signal.

By default, the signal handler will be called before the default signal handler.

For instance, connect_notify( sigc::mem_fun(*this, &TheClass::on_something) );

If the signal requires signal handlers with a `void` return type, the only difference between connect() and connect_notify() is the default value of after.

If the signal requires signal handlers with a return value of type T, connect_notify() binds `return T()` to the connected signal handler. For instance, if the return type is `bool`, the following two calls are equivalent.

connect_notify( sigc::mem_fun(*this,& TheClass::on_something) );
connect( sigc::bind_return<bool>(sigc::mem_fun(*this,& TheClass::on_something), false), false
);

Parameters

  slot | The signal handler, which should have a `void` return type, usually created with sigc::mem_fun() or sigc::ptr_fun().
  after | Whether this signal handler should be called before or after the default signal handler.

## connect_notify() [2/2]

template <class R , class... T>

sigc::connection Glib::SignalProxyDetailedAnyType< R, T >::connect_notify | ( | VoidSlotType&& | slot,
|  | bool | after = `false`
| ) |  |

inline

Connects a signal handler without a return value to a signal.

See also
  connect_notify(const VoidSlotType& slot, bool after).
