Class

Gtk.EventControllerMotion

Description [src]

final class Gtk.EventControllerMotion : Gtk.EventController {
  /* No available fields */
}

GtkEventControllerMotion is an event controller tracking the pointer position.

The event controller offers GtkEventControllerMotion::enter and GtkEventControllerMotion::leave signals, as well as GtkEventControllerMotion:is-pointer and GtkEventControllerMotion:contains-pointer properties which are updated to reflect changes in the pointer position as it moves over the widget.
