### Class

# Gtk EventControllerFocus

#### Description [src]

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

Tracks keyboard focus.

The event controller offers `GtkEventControllerFocus::enter` and `GtkEventControllerFocus::leave` signals, as well as `GtkEventControllerFocus:is-focus` and `GtkEventControllerFocus:contains-focus` properties which are updated to reflect focus changes inside the widget hierarchy that is rooted at the controllers widget.
