After some significant time of reading and trying I found out that it will work with boost::function instead of boost::signal (didn't know of boost::function before). boost::function is enough for me cause I'm not using multiple slots. Anyway I would be interestet in wheter it is possible to have a vector< boost::signal<...> > so long and thanks for thinkin about my former problem :-) Am Wed, 07 Sep 2005 18:42:54 +0200 schrieb kartoffelsack :

Hi!

I'd like to save any kind of functions/functors with void as parameter and as return-value in a container. I thought to use boost::bind:

Let me show you some code:

void bar( ) { }

struct Foo { void operator(); }foo;

typedef boost::signal voidFunctionSig;

std::vector< voidFunctionSig> voidFunctions;

voidFunctionSig signal1; voidFunctionSig signal2;

signal1.connect( &bar); signal2.connect( &foo);

voidFunctions.push_back( signal1); //error voidFunctions.push_back( signal2); //same error

I'm getting a Compiler-errors in the push_back-Lines:

'boost::signal<Signature>::__ctor': no nonexplicit constructor for implicit conversion: with [ Signature=void (void) ] and [ Signature=void (void) ]

well, i'm not shure if boost::bind is the right choice at all, because I do not need multiple slots. Perhaps boost::bind/boost::mem_fn was enough but i cannot think how to use it.

Can anybody help me to save my void (*)(void)-functions/functors and in a container? I could do it writing a superclass and a virtual op() but I would prefer to use ready-to-use boost-classes for this task.

PS: using VC 7.1
