### Class

# Gtk EventController

#### Description [src]

    abstract class Gtk.EventController : GObject.Object
    {
      /* No available fields */
    }

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 `gtk_widget_add_controller()`. It is rarely necessary to explicitly remove a controller with `gtk_widget_remove_controller()`.

See the chapter on input handling for an overview of the basic concepts, such as the capture and bubble phases of event propagation.
