EventControllerFocus

open class EventControllerFocus(pointer: <Error class: unknown class><<Error class: unknown class>>) : EventController

GtkEventControllerFocus is an event controller to keep track of keyboard focus.

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