Are you sure that you do? The equivalent of

    b1->clicked_signal = my_callback_1;

    b2->clicked_signal = my_callback_2;

    b3->clicked_signal = my_callback_3;

would require three new 'button' subclasses. Even if the above requires
three brand new functions to be written (which is rarely the case, I usually
boost::bind existing functions), it's still less code.
