I can add things like a GtkButton to GtkPopoverMenu in Glade, but how to add menu items? Is it possible in Glade, or do I have to do it programmatically?

More info: I am trying to make a mockup of a Miller Column file browser.
I am pretty happy with my creation, except for the problem that the scrolled window gets priority. I want the panes to have priority, so that the user can increase the width of a pane, which will in turn increase the overall width of the scrolled window.
I thought of implementing something like 'ScrolledWindow property set width', but I am not finding any information like that. Or how to detect the paned bar being maxed out.
I am trying to make an example of a proper Gtk.HeaderBar with Gtk.PopoverMenus that shows how the different widgets are used. I looked at a lot of examples and code, but can't figure out, how to work the Gtk.ModelButton.
Especially this sentence makes no sense to me:
When the action is specified via the “action-name” and “action-target” properties, the role of the button (i.e. whether it is a plain, check or radio button) is determined by the type of the action and doesn't have to be explicitly specified with the “role” property.
In any case, here is my attempt to just use normal widgets in the PopoverMenu, leading to inconsistent highlighting (the whole row should be highlighted):
So my question is: How are ModelButtons subclassed, so they appear as proper PopoverMenu-widgets?
Here is the Python code:
from gi.repository import Gtk, Gio
class HeaderBarWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="HeaderBar & PopoverMenu")
self.set_border_width(10)
self.set_default_size(400, 400)
builder = Gtk.Builder()
objects = builder.add_objects_from_file("popovermenu_layout.xml", ("pom_options", ""))
pom_opt = builder.get_object("pom_options")
builder.connect_signals(self)
hb = Gtk.HeaderBar()
hb.set_show_close_button(True)
hb.props.title = "HeaderBar & PopoverMenu"
self.set_titlebar(hb)
def on_click(button, popovermenu):
"""
Toggles the respective popovermenu.
"""
if popovermenu.get_visible():
popovermenu.hide()
else:
popovermenu.show_all()
button_opt = Gtk.Button()
icon = Gio.ThemedIcon(name="format-justify-fill-symbolic")
image = Gtk.Image.new_from_gicon(icon, Gtk.IconSize.BUTTON)
button_opt.add(image)
hb.pack_end(button_opt)
pom_opt.set_relative_to(button_opt)
button_opt.connect("clicked", on_click, pom_opt)
self.add(Gtk.TextView())
def print_something(self, modelbutton, event):
print("you pressed a button")
def night_mode_switcher(self, switch, state):
Gtk.Settings.get_default().set_property("gtk-application-prefer-dark-theme", state)
win = HeaderBarWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()
And here is the model for the PopoverMenu:
<interface>
<object class="GtkPopoverMenu" id ="pom_options">

I managed to solve most of what my question was. Most importantly it seems that one has to use Gtk.Application and Gtk.ApplicationWindow. I can't say that I fully understand why, but that makes it possible to add Actions in the form of Gio.SimpleActions to the application. Gtk.Builder parses the XML of the menu, and one can simply add it tot the menu using the set_popover-method. Then for each action defined in the XML (don't forget the app.-prefix in the XML) a Gio.SimpleAction is created (without the app.-prefix as name) in the Python-code and added to the application. I got a normal button, and a checkbutton to work. Still struggling with the radiobutton, but that might be another question.
Here is the Python-code:
from gi.repository import Gio, Gtk, GLib
import sys
class MainApplication(Gtk.Application):
def __init__(self):
Gtk.Application.__init__(self,
application_id="needs.dot",
flags=Gio.ApplicationFlags.FLAGS_NONE)
#https://developer.gnome.org/gio/unstable/GApplication.html#g-application-id-is-valid
self.connect("activate", self.activate_window)
def activate_window(self, app):
"""
The activate signal of Gtk.Application passes the MainApplication class
to the window. The window is then set as a window of that class.
"""
self.window = Gtk.ApplicationWindow()
self.window.set_default_size(500, 400)
self.hb = Gtk.HeaderBar()
self.hb.set_show_close_button(True)
self.hb.props.title = "HeaderBar & PopOverMenu"
self.window.set_titlebar(self.hb)
button_settings = Gtk.MenuButton()
icon = Gio.ThemedIcon(name="format-justify-fill-symbolic")
image = Gtk.Image.new_from_gicon(icon, Gtk.IconSize.BUTTON)
button_settings.add(image)
self.hb.pack_end(button_settings)
self.builder = Gtk.Builder()
self.builder.add_from_file("popovermenu_layout.xml")
pom_options = self.builder.get_object("pom_options")
button_settings.set_popover(pom_options)
#self.builder.connect_signals(self) #Not needed because of using actions?
app.add_window(self.window)
#Connects to the action. The first part of the XML name is left away:
#<property name="action-name">app.print</property>
#becomes simply "print".
action_print = Gio.SimpleAction.new("print", None)
action_print.connect("activate", self.print_something)
app.add_action(action_print)
#app.toggle becomes -> toggle
action_toggle = Gio.SimpleAction.new_stateful("toggle", None, GLib.Variant.new_boolean(False))
action_toggle.connect("change-state", self.toggle_toggled)
app.add_action(action_toggle)
btn = Gtk.Button("Button")
self.window.add(btn)
self.window.show_all()
def print_something(self, action, variable):
print("something")
def toggle_toggled(self, action, state):
action.set_state(state)
Gtk.Settings.get_default().set_property("gtk-application-prefer-dark-theme", state)
def on_action_quit_activated(self, action):
self.app.quit()
if __name__ == "__main__":

I've written a very simple program with Glade 3.16.1 and GTK+ 3.0 (version 3.10.8) but almost nothing works.
Signal handler gtk_main_quit is not found and the menu is not displayed.
I build the program with
gcc gtktest.c -o gtktest -Wall $(pkg-config --cflags --libs gtk+-3.0 gmodule-2.0)
Source code (gtktest.c):
#include <gtk/gtk.h>
#include <string.h>
void kleine_callback (GtkWidget *w, gpointer d)
{
GtkWidget *dialog;
dialog = gtk_message_dialog_new (NULL,
GTK_DIALOG_DESTROY_WITH_PARENT, GTK_MESSAGE_INFO, GTK_BUTTONS_CLOSE, "Hallo, Welt!");
gtk_dialog_run (GTK_DIALOG (dialog));
gtk_widget_destroy (dialog);
}
void quit (GtkWidget * w, gpointer d)
{
gtk_main_quit ();
}
int main (int argc, char *argv[])
{
GtkBuilder *builder;
GError *error = NULL;
GtkWidget *window;
gtk_init (&argc, &argv);
builder = gtk_builder_new ();
if (!gtk_builder_add_from_file (builder, "kaixN.glade", &error)) {
g_warning ("%s", error->message);
g_free (error);
return 1;
}
gtk_builder_connect_signals (builder, NULL);
window = GTK_WIDGET(gtk_builder_get_object (builder, "main_window"));
gtk_widget_show_all (window);
gtk_main ();
return 0;
}

Everything is so simple, I can't see what I'm doing wrong...
Thx
Kai
Fixed it. The problem was:
1: Signals weren't connected correctly to events.
2: The menu is there but I looked simply at the wrong place. I'm using Ubuntu with Unity so the menu is showing up at the top of the monitor and not at the top of the application window. This post brought my attention to the issue: https://askubuntu.com/questions/460819/ubuntu-gtk-3-10-8-not-able-to-visualize-a-menubar-made-by-glade
I am trying to make sustom modal dialog with glade.
For this I use "dialog box" from "toplevels", set transient_for_window and modal variables properly. Then I put widgets to table all packed into dialog-vbox.
And this works OK, as expected.
But, when I need more complex GUI, like I need now, and pack into dialog-vbox scrolledwindow> viewport> aspectframe> table> and then place widgets in table this dialog becomes no more modal! After some playing I conclude that it is obvious that problems with modality starts with scrolledwindow.
Is it allowed to put such complex GUI in dialog? If yes - why my dialog lost modality with gtkscrollwindow, if no, how people do such tasks? In my case I'm trying to make modal dialog which can be connected to different projects (say reusable).

$window->show_all();
# Dealloc builder

But it falsely connects "on_radiobutton1_group_changed" with "destroy" signal from "top_window". I know this because it executes "print Dumper..." statement only when closing window. Does anyone has idea what I'm doing wrong?
The "group-changed" signal
Emitted when the group of radio buttons that a radio button belongs to changes. This is emitted when a radio button switches from being alone to being part of a group of 2 or more buttons, or vice-versa, and when a button is moved from one group of 2 or more buttons to a different one, but not when the composition of the group that a button belongs to changes.
It really doesn't sound like what you want. I'm guessing it is called on destruction of the window.
I added the following sub
sub on_radiobutton_toggled {
my $self = shift;
if ($self->get_active) {
print Dumper($self, $self->get_label);
}
}
and set the each radiobutton's toggled signal (under GtkToggleButton) to on_radiobutton_toggled, which now does what you want.
