Class HierarchyEvent

java.lang.Object

java.util.EventObject

java.awt.AWTEvent

vaadinx.awt.event.HierarchyEvent

All Implemented Interfaces:

Serializable

public class HierarchyEvent
extends AWTEvent

Port of HierarchyEvent. In AWT this extends AWTEvent directly (not ComponentEvent), and we do the same — the source is typed as Object on AWTEvent, so our Component fits.

Carries the "changed" component (the one whose parent moved), the "changedParent" (its new parent at event time), and a bitmask of what changed. Component.fireHierarchyEvent dispatches it with all three.
