Root

interface Root : Native

GtkRoot is the interface implemented by all widgets that can act as a toplevel widget.

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.
