Re: containers of boost::function objects

Dereferencing an iterator into that list should give you a reference to a boost::function2 object. If BCB6 is calling that function object, it has a Very Big Problem.

I'll look into this further next week, and see if I can produce an interesting test case. As you point out, what I am trying to do here is not valid anyway!

Granted, you wouldn't be able to search the list for a particular function object anyway, because boost::function objects can't be compared.

Yup, I spotted I had mis-read the docs right after posting. My bad.

I suggest either: (1) associate some additional data with each callback that is unique to that callback (e.g., an integer or string value) and use std::map >, or

Yes, this is what I have done <g>

(3) use Signals to do #2 for you

I tried looking at signals a while back, but hit problems with either my understanding or the compiler. However, solving this sure makes me feel like I'm re-inventing the wheel! It's high on my list of things to look into after the ACCU. -- AlisdairM
