Every GNOME app has an "About <App>" item last in its primary menu, opening an
AdwAboutDialog.
menu primary_menu {
section {
item { label: _("_About My App"); action: "app.about"; }
}
}
Label is "About <full app name>", always the last item, no ….
If the app ships AppStream metainfo (it should), let libadwaita read it — release notes, developer, website all come from one place:
def _on_about(self, action, param):
about = Adw.AboutDialog.new_from_appdata(
'/org/example/MyApp/org.example.MyApp.metainfo.xml', '1.2.0')
about.set_copyright('© 2026 Developer')
about.present(self.props.active_window)
(Requires the metainfo XML in gresources.) Rust:
adw::AboutDialog::from_appdata(path, Some("1.2.0")).
about = Adw.AboutDialog(
application_name='My App',
application_icon='org.example.MyApp', # = app ID
version='1.2.0',
developer_name='Jane Developer', # person or team, not company boilerplate
developers=['Jane Developer', 'Sam Contributor'],
designers=['Alex Designer'],
translator_credits=_('translator-credits'), # translated by each locale

about.add_link(_("_Documentation"), "https://example.org/docs")
