Interface SHierarchyListener

All Superinterfaces:
EventListener
public interface SHierarchyListener extends EventListener
Surrogate-side port of HierarchyListener. Single callback — fires on attach, detach, and ancestor hierarchy changes.

Under the Vaadin-first stance (SD_vaadin_first_binding), registrations wire a Vaadin attach/detach subscription on the peer; the dispatched SHierarchyEvent carries SHierarchyEvent.PARENT_CHANGED / SHierarchyEvent.DISPLAYABILITY_CHANGED / SHierarchyEvent.SHOWING_CHANGED flags computed from the attach/detach transition.
