Consider subclassing whatever container widget (you've been talking
about buttons) you'll wind up using to

*) associate the meta data (I think I've read "images", but have
   only skimmed the posts thus far)

*) avoid having to manage the signal handlers by overriding the
   Gtk::Widget::on_drag_data_get() and Gtk::Widget::on_drag_data_received()
   virtual functions
      - they are called just like a signal handler would have been
      - can access your subclass' meta data directly

food for thought that might save you some time ...
