GtkApplicationWindow implements AtkImplementorIface, GtkBuildable, GActionGroup and GActionMap.
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 "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.
Example 111. A GtkApplicationWindow with a menubar
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);
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.
GtkWidget * gtk_application_window_new (GtkApplication *application
);
Creates a new GtkApplicationWindow.

a GtkApplication |
Returns : |
a newly created GtkApplicationWindow |
Since 3.4
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.
|
a GtkApplicationWindow |
|
whether to show a menubar when needed |
Since 3.4
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.
|
a GtkApplicationWindow |
Returns : |
TRUE if window will display a menubar when needed |
Since 3.4
guint gtk_application_window_get_id (GtkApplicationWindow *window
);
Returns the unique ID of the window. If the window has not yet been added to
a GtkApplication, returns 0
.
|
a GtkApplicationWindow |
Returns : |
the unique ID for window , or 0 if the window
has not yet been added to a GtkApplication
|
Since 3.6
"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
