Class SAncestorEvent

java.lang.Object

java.util.EventObject

java.awt.AWTEvent

com.vaadin.swingbridge.surrogates.awt.event.SAncestorEvent

All Implemented Interfaces:

Serializable

public class SAncestorEvent
extends AWTEvent

Surrogate-side port of AncestorEvent. Source type retyped from JComponent to Vaadin Component; ancestor / ancestorParent retyped from Container to Component for the same reason (SD_event_port_stance).

Constants (ANCESTOR_ADDED / ANCESTOR_REMOVED / ANCESTOR_MOVED) preserved verbatim from JDK so id-arithmetic carries across.

SAncestorEvent

public SAncestorEvent(com.vaadin.flow.component.Component source,
 int id,
 com.vaadin.flow.component.Component ancestor,
 com.vaadin.flow.component.Component ancestorParent)

Parameters:

source - the component whose ancestor relationship changed

id - one of ANCESTOR_ADDED / ANCESTOR_REMOVED / ANCESTOR_MOVED

ancestor - the ancestor component that was added / removed / moved (typically the source itself for direct attach/detach events)

ancestorParent - the ancestor's parent at the moment of the event (null when the source has no parent)

Method Details

getAncestor

public com.vaadin.flow.component.Component getAncestor()

The ancestor whose state changed.

getAncestorParent

public com.vaadin.flow.component.Component getAncestorParent()

Parent of getAncestor() at the time of the event.

getComponent

public com.vaadin.flow.component.Component getComponent()

Convenience — same as (Component) getSource().
