Boost::IntrusiveList with Shared Pointers

So I'm writing an event handling system using FastDelegate<> and the boost library. I need to setup a Queue of shared pointers to event data as well as a list of FastDelegate> for listeners. So here's the problem.

Intrusive list and queue don't allow shared_ptr or even constant references which makes my code cause compile time errors. Anyway that I can do this?

It seems safest to hand off a shared ptr to delegates that way the event stays around until everyone is truly done with it.

Q. Intrusive list and queue don't allow shared_ptr

No problem:

Live On Coliru

#include <boost/intrusive/list.hpp>
#include <boost/shared_ptr.hpp>

struct Event {};

struct Node : boost::intrusive::list_base_hook<> {
    boost::shared_ptr<Event> event { new Event };
};

typedef boost::intrusive::list<Node> event_list;

int main() {
    std::vector<Node> nodes(10);

    event_list pending;
    pending.push_back(nodes[3]);
    pending.push_back(nodes[7]);
}

From the fact that you expected (?) intrusive::list<T> to work for T = shared_ptr<...> tells me that you want a simple std::list (or just a std::vector) instead.

or even constant references

Constant references are no problem either. Did you want to use shared_ptr<const Event>? Because that's a good option if you're sharing the event with multiple parties.
