boost::bind & boost::function pointers to overloaded or templated member functions

Question

I have a callback mechanism, the classes involved are:

class App
{
    void onEvent(const MyEvent& event);
    void onEvent(const MyOtherEvent& event         


        

Answer 1

I think you need to disambiguate the address of the overloaded function. You can do this by explicitly casting the function pointer to the one with the correct parameters.

boost::bind( static_cast<void (App::*)( MyEvent& )>(&App::OnEvent) , this, _1);

Answer 2

You are going to want to do

boost::function<void (const MyEvent&)> g = boost::bind(&App::OnEvent, this, _1);

You should be able to do g(event); with that

I am not quite sure what you are trying to accomplish here, but that should solve one of your problems for now.
