Detailed Description

template <class T_return, class T_arg1, class T_arg2, class T_arg3, class T_arg4, class T_arg5>
class sigc::slot< T_return, T_arg1, T_arg2, T_arg3, T_arg4, T_arg5, nil, nil >

Convenience wrapper for the numbered sigc::slot5 template.

See the base class for useful methods. This is the template specialization of the unnumbered sigc::slot template for 5 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;

inline

Constructs a slot from an arbitrary functor.

Parameters

_A_func

The desired functor the new slot should be assigned to.

inline

Constructs a slot, copying an existing one.

Parameters

src	The existing slot to copy.

slot() [4/4]

template <class T_return , class T_arg1 , class T_arg2 , class T_arg3 , class T_arg4 , class T_arg5 >

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.
