I think you can do it by providing a custom widget via
TreeViewColumn::set_widget():
http://www.gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGtk_1_1TreeViewColumn.html#3b8c4e3b7e8b579090440c50843efd26

Of course, you then have to reimplement other functionality, which is
annoying, so I filed a bug about it.
http://bugzilla.gnome.org/show_bug.cgi?id=141937

That bug mentions a hacky way to do it, using gobj()->button on the
Gtk::TreeViewColumn, but I don't like it much:
