Class AttributeChangeEvent

java.lang.Object
java.util.EventObject
javax.faces.event.FacesEvent
org.apache.myfaces.trinidad.event.AttributeChangeEvent

All Implemented Interfaces:

Serializable

public class AttributeChangeEvent

extends javax.faces.event.FacesEvent

Event delivered when a renderer-specific attribute has been changed as a result of user interaction. This event gives advanced Renderers a chance to inform a generic UIXComponent that some portion of it's appearance has been manipulated. For example, a "splitter" panel renderer could indicate that the proportions of the splitter have changed.

AttributeChangeEvents are not delivered in response to programmatic manipulation of a renderer-specific attribute. They must be explicitly queued by a Renderer when it detects that the user had manipulated the component. Developers should not abuse this event as a one-size-fits-all generic component event. When a generic component event changes - like "value" or "disclosed", deliver a strongly-typed component event such as ValueChangeEvent or DisclosureEvent.
