## Detailed Description

### template <class T_return, class T_arg1, class T_arg2, class T_arg3, class T_arg4, class T_arg5, class T_arg6, class T_accumulator = nil>
class sigc::signal6< T_return, T_arg1, T_arg2, T_arg3, T_arg4, T_arg5, T_arg6, T_accumulator >

Signal declaration.

signal6 can be used to connect() slots that are invoked during subsequent calls to emit(). Any functor or slot can be passed into connect(). It is converted into a slot implicitely.

If you want to connect one signal to another, use make_slot() to retrieve a functor that emits the signal when invoked.

Be careful if you directly pass one signal into the connect() method of another: a shallow copy of the signal is made and the signal's slots are not disconnected until both the signal and its clone are destroyed which is probably not what you want!

An STL-style list interface for the signal's list of slots can be retrieved with slots(). This interface supports iteration, insertion and removal of slots.

The following template arguments are used:

- T_return The desired return type for the emit() function (may be overridden by the accumulator).
- T_arg1 Argument type used in the definition of emit().
- T_arg2 Argument type used in the definition of emit().
- T_arg3 Argument type used in the definition of emit().
- T_arg4 Argument type used in the definition of emit().
- T_arg5 Argument type used in the definition of emit().
- T_arg6 Argument type used in the definition of emit().
- T_accumulator The accumulator type used for emission. The default `nil` means that no accumulator should be used, i.e. signal emission returns the return value of the last slot invoked.

You should use the more convenient unnumbered sigc::signal template.

iterator sigc::signal6<T_return, T_arg1, T_arg2, T_arg3, T_arg4, T_arg5, T_arg6, T_accumulator>::connect | ( | const slot_type& | slot_ | ) | `[inline]`

Add a slot to the list of slots.

Any functor or slot may be passed into connect(). It will be converted into a slot implicitely. The returned iterator may be stored for disconnection of the slot at some later point. It stays valid until the slot is removed from the list of slots. The iterator can also be implicitely converted into a sigc::connection object that may be used safely beyond the life time of the slot.

Parameters:

  | slot_ | The slot to add to the list of slots.

Returns:
  An iterator pointing to the new slot in the list.

|  | typename type_trait<T_arg6>::take | _A_a6 |
| ) |  |  | const`[inline]`

Triggers the emission of the signal.

During signal emission all slots that have been connected to the signal are invoked unless they are manually set into a blocking state. The parameters are passed on to the slots. If T_accumulated is not `nil`, an accumulator of this type is used to process the return values of the slot invocations. Otherwise, the return value of the last slot invoked is returned.

Parameters:

  | _A_a1 | Argument to be passed on to the slots.
  | _A_a2 | Argument to be passed on to the slots.
  | _A_a3 | Argument to be passed on to the slots.
  | _A_a4 | Argument to be passed on to the slots.
  | _A_a5 | Argument to be passed on to the slots.
  | _A_a6 | Argument to be passed on to the slots.

Returns:
  The accumulated return values of the slot invocations.
