You can iterate over the properties. The get_properties() function here does that, after instantiating an object of a particular type http://cvs.gnome.org/viewcvs/glibmm/tools/extra_defs_gen/generate_extra_defs.cc?view=markup You would just need to add some code to get the values of a specified instance. -- Murray Cumming murrayc@xxxxxxxxxxx www.murrayc.com www.openismus.com _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
