## Detailed Description

### template<class R>
class Glib::SignalProxy0< R >

Proxy for signals with 0 arguments.

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

## Member Function Documentation

template <class R >

sigc::connection Glib::SignalProxy0< R >::connect | ( | const SlotType& | slot,
|  | bool | after = `true`
| ) |  |

inline

Connects a signal to a signal handler.

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.

template <class R >

sigc::connection Glib::SignalProxy0< R >::connect_notify | ( | const VoidSlotType& | slot,
|  | bool | after = `false`
| ) |  |

inline

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

By default, the signal handler will be called before the default signal handler, in which case any return value would be replaced anyway by that of the later signal handler.

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

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.
