There should be no need to use the C API. Gio::Application has a signal_open(). However, I think it's simpler to derive your own Application class, like so: https://git.gnome.org/browse/gtkmm-documentation/tree/examples/book/application/simple/exampleapplication.cc That then overrides on_open(), which is the default signal handler for the "open" signal. (These new Gtk::Application examples are not described in the gtkmm book's text yet.) > (3) Call a non-static open() function from that signal handler. > > But, given that > > virtual void Gio::Application::on_open (...) > > exists, I guess there is a different way that one is supposed to be able > to do it, without grubbing around with void*'s? Yes.
