That won't help... it is one single menu:
auto object = m_refBuilder->get_object("menu-linuxchess");
auto gmenu = Glib::RefPtr::cast_dynamic(object);
if (!gmenu) {
g_warning("GMenu not found");
}
else
{
set_menubar(gmenu);
}

Re: Merging UI strings into Gtk::Builder?
Both definitions specify the same string for the menu id, so the second definition updates/overwrites the first one. Try using 'menu-linuxchess-2' in the second one...

Re: Please help
Hi aitor, thank you so much for your examples! I will definitely study them in depth as soon as I get my current problem resolved of how to add a 'Mode' to my menu having a separate Gtk::Builder (aka, how to combine multiple Gtk::Builder objects into a single menu). Or, alternatively, I could have just a single Gtk::Builder object, but then I still need to be able to somehow add a Gio::SimpleActionGroup to my menu. It seems that your approach is entirely different: you have a MenuBar class that deals with everything related to the menu. From an object oriented point of view that makes a lot of sense. You're not using Gtk::Builder at all, but - instead of using an xml string - hardcode the menu into the constructor of myMenuBar. For some reason you're passing `*this` to every sigc::mem_fun - aka *all* `on_menu_*` menu callbacks are member functions of myMenuBar. I'd prefer it if I could use callbacks that are member functions of several different objects (namely those that they operate on). I suppose I can do that by passing a pointer to all those objects to the constructor of myMenuBar. Currently you pass only a WindowMain*, for the on_menu_mode_quit method. Why are you using the construct of passing this WindowMain* as an argument to myMenuBar::on_menu_mode_quit? Wouldn't it be possible, and make more sense, to do: m_QuitItem->signal_activate().connect ( sigc::mem_fun(*caller, ::on_menu_mode_quit) ); ?

Thanks, Carlo Wood Look at https://gitlab.gnome.org/GNOME/gtkmm-documentation/-/blob/gtkmm-3-24/examples/book/menus_and_toolbars/examplewindow.cc I think that's what you can do. Create a Gio::SimpleActionGroup. Add your actions to it. Insert it in your widget with Gtk::Widget's insert_action_group() method. In the call to insert_action_group() you choose what prefix to use in the ui file. ___ gtkmm-list mailing list gtkmm-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtkmm-list

I don't have to research that :p. I realized that this is possible
when Glib::ObjectBase is a virtual base class; that is why I looked
on https://developer.gnome.org/glibmm/stable/classGio_1_1ActionMap.html
and since there I saw no indication whatsoever that ObjectBase would
be a virtual base class, I concluded it wasn't :/.
I hope my other questions can be answered too, since Kjell said
that deriving from Gio::ActionMap was very unusual and apparently
not the route I should take.
Is there an example somewhere that shows how I can combine the
`void on_menu_mode_*()` member functions of a widget that is not
derived (indirectly) from Gio::ActionMap to the menu of the window
that this widgets belongs to?
Thanks,
Carlo Wood
