Detailed Description
template <class T_return, class T_arg1, class T_arg2, class T_arg3, class T_arg4, class T_accumulator = ::sigc::nil>
class SigC::Signal4< T_return, T_arg1, T_arg2, T_arg3, T_arg4, T_accumulator >
Signal declaration.
Signal4 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 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_accumulator The accumulator type used for emission. The default
nil
means that no accumulator should be used. Signal emission returns the return value of the last slot invoked.
- Deprecated:
- Use the unnumbered template sigc::signal instead.
