Constructor & Destructor Documentation

template<typename T >

qi::SignalF< T >::SignalF ( OnSubscribers onSubscribers = OnSubscribers() )

Signal constructor

Parameters

onSubscribers invoked each time number of subscribers switch between 0 and 1, with argument '!subscribers.empty()' Will not be called when destructor is invoked and all subscribers are removed

Definition at line 150 of file signal.hxx.

template<typename T >

qi::SignalF< T >::SignalF	(	ExecutionContext *	execContext,
		OnSubscribers	onSubscribers
	)

Member Function Documentation

template<typename T>

SignalSubscriber qi::SignalF< T >::connect ( ... )

Connect a subscriber to this signal.

Multiple forms can be used:

connect(function, argOrPlaceholder1, argOrPlaceholder2, ...) Where function is a function or callable object (such as a boost::function). If the first argument is a weak ptr or inherits qi::Trackable, the slot will automatically disconnect if object is no longuer available.
connect(AnyObject target, unsigned int slot)
connect(AnyObject target, const std::string& slotName)
connect(AnyFunction func)
connect(const SignalSubscriber&)
connect(qi::Signal<U>& otherSignal)

Warning: This function is synchronous and may block the current thread, which may be in charge of dispatching results that could be waited for. Please prefer connectAsync to be totally safe from subtle deadlocks in your programs.

Returns: a SignalSubscriber object. This object can be implicitly converted to a SignalLink.

Exceptions

runtime_error if the connection could not be made (because of invalid callback arity or argument type)
