/**
* SECTION:gtkapplicationwindow
* @title: GtkApplicationWindow
* @short_description: GtkWindow subclass with GtkApplication support
*
* GtkApplicationWindow is a #GtkWindow subclass that offers some
* extra functionality for better integration with #GtkApplication
* features. Notably, it can handle both the application menu as well
* as the menubar. See gtk_application_set_app_menu() and
* gtk_application_set_menubar().
*
* This class implements the #GActionGroup and #GActionMap interfaces,
* to let you add window-specific actions that will be exported by the
* associated #GtkApplication, together with its application-wide
* actions. Window-specific actions are prefixed with the "win."
* prefix and application-wide actions are prefixed with the "app."
* prefix. Actions must be addressed with the prefixed name when
* referring to them from a #GMenuModel.
*
* Note that widgets that are placed inside a GtkApplicationWindow
* can also activate these actions, if they implement the
* GtkActionable interface.
*
* As with #GtkApplication, the GDK lock will be acquired when
* processing actions arriving from other processes and should therefore
* be held when activating actions locally (if GDK threads are enabled).
*
* The settings #GtkSettings:gtk-shell-shows-app-menu and
* #GtkSettings:gtk-shell-shows-menubar tell GTK+ whether the
* desktop environment is showing the application menu and menubar
* models outside the application as part of the desktop shell.
* For instance, on OS X, both menus will be displayed remotely;
* on Windows neither will be. gnome-shell (starting with version 3.4)
* will display the application menu, but not the menubar.
*
* If the desktop environment does not display the menubar, then
* #GApplicationWindow will automatically show a #GtkMenubar for it.
* (see the #GtkApplication docs for some screenshots of how this
* looks on different platforms).
* This behaviour can be overridden with the #GtkApplicationWindow:show-menubar
* property. If the desktop environment does not display the application
* menu, then it will automatically be included in the menubar.
*
* <example><title>A GtkApplicationWindow with a menubar</title>
* <programlisting><![CDATA[
* app = gtk_application_new ();
*
* builder = gtk_builder_new ();
* gtk_builder_add_from_string (builder,
* "<interface>"
* " <menu id='menubar'>"
* " <submenu label='_Edit'>"
* " <item label='_Copy' action='win.copy'/>"
* " <item label='_Paste' action='win.paste'/>"
* " </submenu>"
* " </menu>"
* "</interface>");
* gtk_application_set_menubar (G_APPLICATION (app),
* G_MENU_MODEL (gtk_builder_get_object (builder, "menubar")));
* g_object_unref (builder);
*
* ...
*
* window = gtk_application_window_new (app);
* ]]>
* </programlisting>
* </example>
*
* The XML format understood by #GtkBuilder for #GMenuModel consists
* of a toplevel <tag class="starttag">menu</tag> element, which contains
* one or more <tag class="starttag">item</tag> elements. Each
* <tag class="starttag">item</tag> element contains
* <tag class="starttag">attribute</tag> and <tag class="starttag">link</tag>
* elements with a mandatory name attribute.
* <tag class="starttag">link</tag> elements have the same content
* model as <tag class="starttag">menu</tag>.
*
* Attribute values can be translated using gettext, like other #GtkBuilder
* content. <tag class="starttag">attribute</tag> elements can be marked for
* translation with a <literal>translatable="yes"</literal> attribute.
* It is also possible to specify message context and translator comments,
* using the context and comments attributes. To make use of this, the
* #GtkBuilder must have been given the gettext domain to use.
