module Gtk::Root

Overview

Gtk::Root 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 Gtk::Root is Gtk::Window.

To get the display to which a Gtk::Root belongs, use Gtk::Root#display.

Gtk::Root also maintains the location of keyboard focus inside its widget hierarchy, with Gtk::Root#focus= and Gtk::Root#focus.
