Signal ID
Connect to Leave signal.
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 propertyGtk.EventControllerFocus:is-focus property for changes.
