Object hierarchy for EventController

Description:

[ CCode ( type_id = "gtk_event_controller_get_type ()" ) ]
public abstract class EventController : Object

`GtkEventController` is the base class for event controllers.

These are ancillary objects associated to widgets, which react to `GdkEvents`, and possibly trigger actions as a consequence.

Event controllers are added to a widget with [method@Gtk.Widget.add_controller]. It is rarely necessary to explicitly remove a controller with [method@Gtk.Widget.remove_controller].

See the chapter of [input handling](input-handling.html) for an overview of the basic concepts, such as the capture and bubble phases of even propagation.
