## Detailed Description

template<class... T>
class Glib::SignalProxy< void(T...)>

Proxy for signals with any number of arguments.

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

This is a specialization for signal handlers that return `void`.

## Member Function Documentation

## ◆ connect() [1/2]

template <class... T>

sigc::connection Glib::SignalProxy< void(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) );

By default, the signal handler will be called after the default signal handler. This is usually fine for signal handlers that don't return a value.

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.

Returns
  A sigc::connection.

## ◆ connect() [2/2]

template <class... T>

sigc::connection Glib::SignalProxy< void(T...)>::connect | ( | SlotType && | slot,
|  | bool | after = `true`
| ) |  |
| inline

Connects a signal handler to a signal.

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