I've been over the documentation several times and I keep getting the feeling that I'm just missing something. I'd like to have some member functions (methods) as slots for some signals (a la QT). I suspect that there is some form of bind that I could use, but it's certainly not obvious to me.

Yep, bind can do it: struct X { int foo(float, char); }; signal<int (X*, float, char)> sig; sig.connect(bind(&X::foo, _1, _2, _3)); // or sig.connect(mem_fn(&X::foo)); The _1 is the implicit object parameter ("this") that the member function pointer is invoked with. Doug
