Detailed Description

sigc::track_object() 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_object() 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.

track_obj() is a deprecated alternative to track_object().

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_object([&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.
