This is what the entire libsigc++ library used by gtkmm solves (i.e.
sigc::mem_fun(...)).  However, I would highly recommend that you try
to get TreeView working instead of attempting to re-implement it.
I've never used gtkmm on windows, but there certainly are people here
that do.  Perhaps if you posted detailed information about your
problems using TreeView on windows somebody on the list could help you
get it working, or maybe we could uncover a bug in gtkmm in the
process.
