CtkApplicationWindow implements AtkImplementorIface, CtkBuildable, GActionGroup and GActionMap.
CtkApplicationWindow is a CtkWindow subclass that offers some
extra functionality for better integration with CtkApplication
features. Notably, it can handle both the application menu as well
as the menubar. See ctk_application_set_app_menu() and
ctk_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 CtkApplication, 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 CtkApplicationWindow can also activate these actions, if they implement the CtkActionable interface.
As with CtkApplication, the CDK lock will be acquired when processing actions arriving from other processes and should therefore be held when activating actions locally (if CDK threads are enabled).
The settings “ctk-shell-shows-app-menu” and “ctk-shell-shows-menubar” tell CTK+ 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 CtkApplicationWindow will automatically show a CtkMenuBar for it. 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 or in the windows client-side decorations.

The XML format understood by CtkBuilder 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>. Instead of <link name="submenu> or
<link name="section">, you can use <submenu> or <section>
elements.
Attribute values can be translated using gettext, like other CtkBuilder
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 CtkBuilder must have been given the gettext
domain to use.
The following attributes are used when constructing menu items:
"label": a user-visible string to display
"action": the prefixed name of the action to trigger
"target": the parameter to use when activating the action
"icon" and "verb-icon": names of icons that may be displayed
"submenu-action": name of an action that may be used to determine if a submenu can be opened
"hidden-when": a string used to determine when the item will be hidden. Possible values include "action-disabled", "action-missing", "macos-menubar".
The following attributes are used when constructing sections:
"label": a user-visible string to use as section heading
"display-hint": a string used to determine special formatting for the section. Possible values include "horizontal-buttons".
"text-direction": a string used to determine the CtkTextDirection to use when "display-hint" is set to "horizontal-buttons". Possible values include "rtl", "ltr", and "none".
The following attributes are used when constructing submenus:
"label": a user-visible string to display
"icon": icon name to display

ctk_application_window_new (CtkApplication *application);
Creates a new CtkApplicationWindow.

void ctk_application_window_set_show_menubar (CtkApplicationWindow *window,gboolean show_menubar);
Sets whether the window will display a menubar for the app menu and menubar as needed.
Since: 3.4
gboolean
ctk_application_window_get_show_menubar
(CtkApplicationWindow *window);
Returns whether the window will display a menubar for the app menu and menubar as needed.
Since: 3.4
guint
ctk_application_window_get_id (CtkApplicationWindow *window);
Returns the unique ID of the window. If the window has not yet been added to
a CtkApplication, returns 0.
Since: 3.6
void ctk_application_window_set_help_overlay (CtkApplicationWindow *window,CtkShortcutsWindow *help_overlay);
Associates a shortcuts window with the application window, and sets up an action with the name win.show-help-overlay to present it.
window
takes resposibility for destroying help_overlay
.
Since: 3.20
CtkShortcutsWindow *
ctk_application_window_get_help_overlay
(CtkApplicationWindow *window);
Gets the CtkShortcutsWindow that has been set up with
a prior call to ctk_application_window_set_help_overlay().
Since: 3.20
“show-menubar” property “show-menubar” gboolean
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 ctk_application_set_app_menu()
and ctk_application_set_menubar().
If FALSE, the window will not display a menubar, regardless
of whether the desktop shell is showing the menus or not.
