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. * * A GtkApplicationWindow with a menubar * " * " " * " " * " " * " " * " " * " " * ""); * 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); * ]]> * * * * The XML format understood by #GtkBuilder for #GMenuModel consists * of a toplevel menu element, which contains * one or more item elements. Each * item element contains * attribute and link * elements with a mandatory name attribute. * link elements have the same content * model as menu. * * Attribute values can be translated using gettext, like other #GtkBuilder * content. attribute elements can be marked for * translation with a translatable="yes" 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. */ typedef GSimpleActionGroupClass GtkApplicationWindowActionsClass; typedef struct { GSimpleActionGroup parent_instance;
