## Implemented Interfaces

GtkApplicationWindow implements AtkImplementorIface, GtkBuildable, GActionGroup and GActionMap.

## Description

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.

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 "gtk-shell-shows-app-menu" and "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 "show-menubar" property. If the desktop environment does not display the application menu, then it will automatically be included in the menubar.

## Details

### struct GtkApplicationWindow

    struct GtkApplicationWindow;

### gtk_application_window_new ()

    GtkWidget *         gtk_application_window_new          (GtkApplication *application);

Creates a new GtkApplicationWindow.

`application` : | a GtkApplication
Returns : | a newly created GtkApplicationWindow

Since 3.4

### gtk_application_window_set_show_menubar ()

    void                gtk_application_window_set_show_menubar
                                                            (GtkApplicationWindow *window,
                                                             gboolean show_menubar);

Sets whether the window will display a menubar for the app menu and menubar as needed.

`window` : | a GtkApplicationWindow
`show_menubar` : | whether to show a menubar when needed

Since 3.4

### gtk_application_window_get_show_menubar ()

    gboolean            gtk_application_window_get_show_menubar
                                                            (GtkApplicationWindow *window);

Returns whether the window will display a menubar for the app menu and menubar as needed.

`window` : | a GtkApplicationWindow
Returns : | `TRUE` if `window` will display a menubar when needed

Since 3.4

## Property Details

### The `"show-menubar"` property

      "show-menubar"             gboolean              : Read / Write / Construct

If this property is `TRUE`, the window will display a menubar that includes the app menu and menubar, unless these are shown by the desktop shell. See `gtk_application_set_app_menu()` and `gtk_application_set_menubar()`.

If `FALSE`, the window will not display a menubar, regardless of whether the desktop shell is showing the menus or not.

Default value: TRUE
