[Boost-users] Boost MPL Subclass list

Hello,

I have the following problem:

I want to add signals to an emitting class in a generic fashion. To add 
a signal data member for every signal type, I inherit privately from a 
list of signal types. I therefore use the mpl::inherit template.

class Emitter:
                private boost::mpl::inherit<
                        boost::signal<void (const Emitter&, int, int)>, // emitted when size 
changes
                           boost::signal<void (const Emitter&, const char*)> // emitted when 
name changes
		> {
public:

};

Since I want some signals to be connected automatically, I need to 
iterate the list of signal types. Is it possible to get a mpl::list 
with all the types I used within mpl::inherit?

Best regards and thanks in advance,

Thomas Immich
