The gtk:root interface is the interface implemented by all widgets that can act as a toplevel widget to a hierarchy of widgets. 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 widget is the gtk:window widget.

To get the display to which a gtk:root widget belongs, use the gtk:root-display function. The gtk:root widget also maintains the location of keyboard focus inside its widget hierarchy, with the gtk:root-focus function.
