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 171 of file signal.hxx.

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)

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)
