Re: [Boost-users] [signals2] connection blocking

I suppose I don't need the connection object at all if the widget itself is trackable. But now that I've looked at the shared_connection_block code, I'm wondering, why is it noncopyable? It looks to me like it could be. If it were copyable/assignable (and ultimately, movable), I wouldn't need t= o dynamically allocate it.

I have correct what I said here. The problem isn't copyability (they are copyable). Its that the shared_connection_block cannot be default-constructed. What would be the repercussions of allowing default construction of shared_connection_block objects? -bryan
