Detailed Description

sigc::track_obj() tracks trackable objects, referenced from a functor.

It can be useful when you assign a C++11 lambda expression or a std::function<> to a slot, or connect it to a signal, and the lambda expression or std::function<> contains references to sigc::trackable derived objects.

The functor returned by sigc::track_obj() is formally an adaptor, but it does not alter the signature, return type or behaviour of the supplied functor. Up to 7 objects can be tracked. operator()() can have up to 7 arguments.

Example:: struct bar : public sigc::trackable {};

sigc::signal<void> some_signal;

void foo(bar&);

{

bar some_bar;

some_signal.connect([&some_bar](){ foo(some_bar); });

// NOT disconnected automatically when some_bar goes out of scope

some_signal.connect(sigc::track_obj([&some_bar](){ foo(some_bar); }, some_bar);

// disconnected automatically when some_bar goes out of scope

}

sigc::signal7::connect
iterator connect(const slot_type &slot_)
Add a slot to the list of slots.
Definition signal.h:3871

sigc::signal
Convenience wrapper for the numbered sigc::signal# templates.
Definition signal.h:4015

sigc::track_obj
track_obj_functor1< T_functor, T_obj1 > track_obj(const T_functor &_A_func, const T_obj1 &_A_obj1)
Creates an adaptor of type sigc::track_obj_functor1 which wraps a functor.

sigc::trackable
Base class for objects with auto-disconnection.
