Class ClientInfoEvent

java.lang.Object

org.zkoss.zk.ui.event.Event

org.zkoss.zk.ui.event.ClientInfoEvent

All Implemented Interfaces:

java.io.Serializable

public class ClientInfoEvent
extends Event

The onClientInfo event is used to notify the client's information, such as time zone and screen resolutions.

This event is sent if and only if it is registered to a root component.

Note: the information returned by this event is not stored in the server. Thus, you might want to store in the session's attribute (Session.setAttribute(java.lang.String, java.lang.Object)).

dtwd - the desktop's width

dthgh - the desktop's height

dtx - the desktop's the left offset

dty - the desktop's the top offset

dpr - the device's devicePixelRatio

orient - the device's orientation

zoneId - the client's zone id
