Re: [Boost-users] Boost:Bind//Boost:Function -- Need some help with a constructor trying to bind to a function

<aside> I don't think you want assign_to_me to be a reference, but just hold by value. Otherwise you're holding a reference to a temporary below. </aside>

Alpha::MethodsInHere mih; EventHandler eh(boost::bind(&Alpha::MethodsInHere::doesSomething, ????, _1))

--------My question is basically if this is possible.  I was having a ton of trouble getting this to work, and after digging through some docs it seems like the '?????' in line of code in #4 needs to be a reference to eh . . . which isn't constructed yet. If I'm wrong, please tell me how to construct this bind properly.  [snip]

Sorry, but you're wrong. You want "????" to be "mih", not "eh". "doesSomething"'s type is basically "(Alpha::MethodsInHere&, POD::POD*) -> void" hence you need and instance of Alpha::MethodsInHere. HTH, -Ryan
