Class ServerActionEvent

java.lang.Object

java.util.EventObject

ilog.views.util.servlet.IlvServerActionEvent

ilog.views.servlet.ServerActionEvent

All Implemented Interfaces:

Serializable

public class ServerActionEvent
extends IlvServerActionEvent

An event object that is sent to listeners of actions requested from the client side. An action is generated from the client side when the ServerActionListener.actionPerformed method is called. This method queries the server for a new image, but additional parameters are sent in the image request so that an action such as adding, removing, or selecting objects can be performed before the image is generated. An action is defined by a name and a list of parameters. To implement the action on the client side, you will implement the ServerActionListener interface and check the action name and parameters in the event.

Since:

JViews 3.5
