Class Iframe

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, org.zkoss.zk.ui.Component, org.zkoss.zk.ui.ext.Scope, org.zkoss.zk.ui.sys.ComponentCtrl
    public class Iframe
extends org.zkoss.zk.ui.HtmlBasedComponent
    Includes an inline frame.

    Unlike HTML iframe, this component doesn't have the frameborder property. Rather, use the CSS style to customize the border (like any other components).

    To handle the onload event, you have to use the client-attribute namespace. Please refer to ZK Component Reference: iframe fore more information.
