mySignal.connect(a);

mySignal.connect(*a); // because connect copy the callback/functor. I guess you have to write a callable_shared_ptr or something. I d'idn't find it in Boost. -- Mickaël Wolff aka Lupus Michaelis Racine http://lupusmic.org Blog http://blog.lupusmic.org

James C. Sutherland:

I want something like

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

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

You can use mySignal.connect( boost::bind( &A::operator(), a ) ); Not pretty, but still a way to achieve what you want without a helper function (object). -- Peter Dimov http://www.pdplayer.com
