## Detailed Description

### template<class T_return, class T_arg1>
class sigc::slot< T_return, T_arg1, nil, nil, nil, nil, nil, nil >

Convenience wrapper for the numbered sigc::slot1 template.

See the base class for useful methods. This is the template specialization of the unnumbered sigc::slot template for 1 argument(s), specialized for different numbers of arguments This is possible because the template has default (nil) template types.

Deprecated:
  Please use the syntax similar to that used by std::function<>:

sigc::slot<void(bool, int)> some_slot;

## Member Typedef Documentation

template <class T_return , class T_arg1 >

typedef slot1<T_return, T_arg1> sigc::slot< T_return, T_arg1, nil, nil, nil, nil, nil, nil >::parent_type

## Constructor & Destructor Documentation

template <class T_return , class T_arg1 >

sigc::slot< T_return, T_arg1, nil, nil, nil, nil, nil, nil >::slot | ( |  | ) |
| inline

template <class T_return , class T_arg1 >
template <class T_functor >

sigc::slot< T_return, T_arg1, nil, nil, nil, nil, nil, nil >::slot | ( | const T_functor & | _A_func | ) |
| inline

Constructs a slot from an arbitrary functor.

Parameters

  _A_func | The desired functor the new slot should be assigned to.

template <class T_return , class T_arg1 >

sigc::slot< T_return, T_arg1, nil, nil, nil, nil, nil, nil >::slot | ( | const slot< T_return, T_arg1, nil, nil, nil, nil, nil, nil >& | src | ) |
| inline

Constructs a slot, copying an existing one.

Parameters

  src | The existing slot to copy.

template <class T_return , class T_arg1 >

sigc::slot< T_return, T_arg1, nil, nil, nil, nil, nil, nil >::slot | ( | slot< T_return, T_arg1, nil, nil, nil, nil, nil, nil >&& | src | ) |
| inline

Constructs a slot, moving an existing one.

If `src` is connected to a parent (e.g. a signal), it is copied, not moved.

Parameters

  src | The existing slot to move or copy.

## Member Function Documentation

template <class T_return , class T_arg1 >

slot& sigc::slot< T_return, T_arg1, nil, nil, nil, nil, nil, nil >::operator= | ( | const slot< T_return, T_arg1, nil, nil, nil, nil, nil, nil >& | src | ) |
| inline

Overrides this slot, making a copy from another slot.

Parameters

  src | The slot from which to make a copy.

Returns
  `this`.

template <class T_return , class T_arg1 >

slot& sigc::slot< T_return, T_arg1, nil, nil, nil, nil, nil, nil >::operator= | ( | slot< T_return, T_arg1, nil, nil, nil, nil, nil, nil >&& | src | ) |
| inline

Overrides this slot, making a move from another slot.

If `src` is connected to a parent (e.g. a signal), it is copied, not moved.

Parameters

  src | The slot from which to move or copy.

Returns
  `this`.
