You need to know the function signature. This is not different from a call through any other function pointer. What sigc::mem_fun() does to make this generic is just a bit of template magic, which has nothing to do with the pointer-to-member-function call itself. In a nutshell, templates allow you to defer the compilation of a piece of code to the point where the template is actually used. Just like macros, really. At that point, the class and the method signature *are* known. That's the trick. --Daniel _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
