gtkmm is signal/slot based too, but because of its closer integration
with C++ idioms, this particular issue doesn't arise too much. you
don't need a pre-processor to use libsigc++ and if you are working in
C++ for any reason, you should be aware of sigc++. its the greatest
thing for C++ since boost (and thankfully, boost includes something
closely modelled on it these days).

signals & slots are a callback mechanism too. they just hide it from
the programmer with a different kind of abstraction (when this signal
is "emitted", call the following "slot"). its all just syntactic
sugar.
