Description:

[ CCode ( type_cname = "GtkRootInterface" , type_id = "gtk_root_get_type ()" ) ]
public interface Root : Widget, Native

An interface for widgets that can act as the root of a widget hierarchy.

The root widget takes care of providing the connection to the windowing system and manages layout, drawing and event delivery for its widget hierarchy.

The obvious example of a `GtkRoot` is `GtkWindow`.

To get the display to which a `GtkRoot` belongs, use [method@Gtk.Root.get_display].

`GtkRoot` also maintains the location of keyboard focus inside its widget hierarchy, with [method@Gtk.Root.set_focus] and [ method@Gtk.Root.get_focus].
