Hi again,
In the next examples i'll explain how to add an icon factory for your custom stock icons and how to add the toolbar to the project. They'll be uploaded to the following link: https://www.gnuinos.org/Gtkmm%20Examples/ Hope this helps,

Quote.- The SeparatorToolItem at the left of the last item is missing in Gtkmm3:

This separator only appears in Gtkmm-2.4 ...
Cheers,
