How to show shortcuts in ShortcutsWindow? - gtk

Question

I would need a simple working example (using Gtkmm 3) of a ShortcutsWindow with just one ShortcutsShortcut that does not use a Gtk::Builder.
I have not been able to find such an example online. I am able to show window however shortcuts do not show.

Here is a very simple example. You can build from it:
#include <gtkmm.h>
#include <iostream>
class MyShortcutsWindow : public Gtk::ShortcutsWindow
{
public:
MyShortcutsWindow();
private:
Gtk::ShortcutsShortcut m_shortcut;
Gtk::ShortcutsGroup m_group;
Gtk::ShortcutsSection m_section;
};
MyShortcutsWindow::MyShortcutsWindow()
{
// Prints Gtkmm version:
std::cout << "Gtkmm version : "
<< gtk_get_major_version() << "."
<< gtk_get_minor_version() << "."
<< gtk_get_micro_version()
<< std::endl;
// 1. Create shorcut:
// -------------------------------------------------------------
// Set title:
auto shortcutTitle = m_shortcut.property_title();
shortcutTitle.set_value("Hit that to search");
// Set type:
auto shortcutType = m_shortcut.property_shortcut_type();
shortcutType.set_value(Gtk::SHORTCUT_ACCELERATOR);
// Set accelerator:
auto shortcutAccelerator = m_shortcut.property_accelerator();
shortcutAccelerator.set_value("<Ctrl>f");
// 2. Create shortcut group:
// -------------------------------------------------------------
m_group.add(m_shortcut);
// 3. Create shortcut section:
// -------------------------------------------------------------
m_section.add(m_group);
// Make sure your section is visible. I have found if this is
// not called, your section won't show until you have tried a
// search first (weird):
auto sectionVisibility = m_section.property_visible();
sectionVisibility.set_value(true);
// 4. Add the section to the window:
// -------------------------------------------------------------
add(m_section);
}
int main(int argc, char *argv[])
{
auto app = Gtk::Application::create(argc, argv, "so.question.q66123196");
MyShortcutsWindow window;
window.show_all();
return app->run(window);
}
It works with Gtkmm version 3.22.30 in my case. You need at most version 3.20 according to the docs.

Following up on BobMorane's answer: Calling show_all() on your Gtk::ShortcutsSection object will provide the same result as setting property_visible to true.
In the example provided:
m_section.add(m_group);
m_section.show_all();
// 4. Add the section to the window:
// -------------------------------------------------------------
add(m_section);
