this is not my recommendation.
I adopted this technique to the sample
implementation which is described below.

I will not use any pre-processor like SWIG.
and don't know the details of SWIG well.

now I find out the nice implementation for me. it is including both of
your idea and my idea. I've put the sample implementation. download the
following archive and refer it.

http://ruby-fltk.sourceforge.net/archive/ruby-fltk-new.tar.gz

in this implementation, we create the subclass RBFLSubXxxx for each
Fl_Xxxx. and in the ruby layer, we will have the class FLXxxx and
FLSubXxxx for the C++ class Fl_Xxxx and RBFLSubXxxx.
there are sample two script in the archive. one is for Fl_Xxxx and
the other shows how to handle the event.
