class Gtk::EventControllerFocus

Overview

Gtk::EventControllerFocus is an event controller to keep track of keyboard focus.

The event controller offers Gtk::EventControllerFocus::#enter and 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.

Defined in:

lib/gi-crystal/src/auto/gtk-4.0/event_controller_focus.cr
