Yes, precisely. > If that accurately reflects where you're at, then you're now creating > a new Gtk:Builder instance each time you read one of those > multiple .glade files, and it's that new instance-per-tab that has > made things work.

This would apparently create potentially dozens of unneeded windows/widgets, then after selecting the widget for the new tab, the rest of them would be destroyed again. Is this correct? As I'm so new to GTK, I'm just trying to work out the pros and cons of single vs multiple .glade files. > You can also dispense with the Gtk::Window if you make your Gtk::Box > a top-level widget (in glade, right-click the Gtk::Box icon in the > widget pane and select "Add widget as toplevel").

After making the Gtk::Box a top-level widget in Glade, I am able to retrieve it and add it to the Notebook without any problem, even using the append_page() variant that lets me supply the tab's title. Many thanks for solving my problem! Cheers, Adam. _______________________________________________ gtkmm-list mailing list gtkmm-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtkmm-list
