struct Gtk::EventControllerFocus::LeaveSignal

Overview

Emitted whenever the focus leaves the widget hierarchy that is rooted at the widget that the controller is attached to.

Note that this means you may not get a ::leave signal even though the focus moves away from the widget, in certain cases (such as when the focus moves from the widget to a descendent). If you are interested in these cases, you can monitor the [property@Gtk.EventControllerFocus:is-focus] property for changes.

Defined in:

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