Class SFocusEvent

java.lang.Object

java.util.EventObject

java.awt.AWTEvent

com.vaadin.swingbridge.surrogates.awt.event.SComponentEvent

com.vaadin.swingbridge.surrogates.awt.event.SFocusEvent

All Implemented Interfaces:

Serializable

public class SFocusEvent
extends SComponentEvent

Surrogate-side port of FocusEvent. Source type retyped from Component to Component; opposite likewise (SD_event_port_stance rationale).

The FocusEvent.Cause enum is deliberately not carried in any constructor overload here — it's a JDK-9+ refinement layered onto an API we already cover with the original two-/three-arg shape. No migration target reads getCause() today; add when one surfaces.

 com.vaadin.flow.component.Component opposite)

Method Details

isTemporary

public boolean isTemporary()

JDK's FocusEvent.isTemporary — true for cross-window focus changes the browser considers ephemeral. Our wiring passes false uniformly; the field is preserved for completeness and for migrated code that reads it through our ported listener.

getOppositeComponent

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

The component losing/gaining focus on the other end of the transition, or null when unknown (our peer subscriptions don't receive the opposite from Vaadin). Matches JDK's null contract for unknown opposite.

paramString

public String paramString()
