Is it possible to use a shared_ptr object in a signal?

I want something like

struct A{ ... void operator()(){ ... } ... }; typedef boost::signal Signal; Signal mySignal;

boost::shared_ptr a( new A() ); mySignal.connect(a);

Wrap the shared_ptr in a function object

struct deref_call { void operator()() const { (*f)(); } boost::shared_ptr f; };

bind can also be used to do this, since shared_ptr can be passed as the "this" argument when binding member functions: boost::shared_ptr a( new A() ); mySignal.connect(boost::bind(&A::operator(), a));
