public interface Enableable<S extends Enableable<S>>

Something the user can be kept from using: every Component, and the entries that controls hold, a MenuItem, CheckMenuItem, RadioMenuItem, SubmenuItem, Tab or NavigationItem. Code that takes an Enableable<?> turns any of them on and off without a branch for each.

It has no events and does not extend EventTarget, so entries, which are not event targets, can have it. Each implementation says what disabled means for it. Binding goes through Component.ENABLED, since entries do not bind.

Do not implement this interface.
