All Implemented Interfaces:

PointerInterface

public class EventControllerMotion
extends EventController

`GtkEventControllerMotion` is an event controller tracking the pointer
position.

The event controller offers [signal@Gtk.EventControllerMotion::enter]
and [signal@Gtk.EventControllerMotion::leave] signals, as well as
[property@Gtk.EventControllerMotion:is-pointer] and
[property@Gtk.EventControllerMotion:contains-pointer] properties
which are updated to reflect changes in the pointer position as it
moves over the widget.
