  40  * @title: GtkApplicationWindow
  41  * @short_description: GtkWindow subclass with GtkApplication support
  42  *
  43  * GtkApplicationWindow is a #GtkWindow subclass that offers some
  44  * extra functionality for better integration with #GtkApplication
  45  * features.  Notably, it can handle both the application menu as well
  46  * as the menubar. See g_application_set_app_menu() and
  47  * g_application_set_menubar().
  48  *
  49  * This class implements the #GActionGroup and #GActionMap interfaces,
  50  * to let you add window-specific actions that will be exported by the
  51  * associated #GtkApplication, together with its application-wide
  52  * actions.  Window-specific actions are prefixed with the "win."
  53  * prefix and application-wide actions are prefixed with the "app."
  54  * prefix.  Actions must be addressed with the prefixed name when
  55  * referring to them from a #GMenuModel.
  56  *
  57  * The settings #GtkSettings:gtk-shell-shows-app-menu and
  58  * #GtkSettings:gtk-shell-shows-menubar tell GTK+ whether the
  59  * desktop environment is showing the application menu and menubar
  60  * models outside the application as part of the desktop shell.
  61  * For instance, on OS X, both menus will be displayed remotely;
  62  * on Windows neither will be. gnome-shell (starting with version 3.4)
  63  * will display the application menu, but not the menubar.
  64  *
  65  * If the desktop environment does not display the menubar, then
  66  * #GApplicationWindow will automatically show a #GtkMenubar for it.
  67  * This behaviour can be overridden with the #GtkApplicationWindow:show-menubar
  68  * property. If the desktop environment does not display the application
  69  * menu, then it will automatilly be included in the menubar.
