We can't add a base class to a C++ class without breaking ABI - that generally means causing all applications that currently use that ABI to crash. Obviously we don't want to do that. It can be done when we do a parallel install such as when we went from gtkmm-2.4 to gtkmm-3.0, which did not affect currently installed applications. You can do this in the meantime: gtk_actionable_set_action_name(theButton.gobj(), "somename"); See: https://developer.gnome.org/gtkmm-tutorial/stable/sec-basics-gobj-and-wrap.html.en -- Murray Cumming murr...@murrayc.com www.murrayc.com _______________________________________________ gtkmm-list mailing list gtkmm-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtkmm-list
