Class

GtkEventController

Description [src] 

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

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 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.
