Description:

[ CCode ( type_id = "gtk_application_window_get_type ()" ) ]
public class ApplicationWindow : Window, ActionGroup, ActionMap, Accessible, Buildable, ConstraintTarget, Native, Root, ShortcutManager

ApplicationWindow is a Window subclass that offers some extra functionality for better integration with Application features.

Notably, it can handle an application menubar. See set_menubar.

This class implements the ActionGroup and ActionMap interfaces, to let you add window-specific actions that will be exported by the associated Application, 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 MenuModel .

Note that widgets that are placed inside a ApplicationWindow can also activate these actions, if they implement the Actionable interface.

As with Application, 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 ApplicationWindow will automatically show a menubar 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.

See PopoverMenu for information about the XML language used by Builder for menu models.
