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.
