Class DHtmlLayoutPortlet

java.lang.Object

javax.portlet.GenericPortlet

org.zkoss.zk.ui.http.DHtmlLayoutPortlet

All Implemented Interfaces:

javax.portlet.EventPortlet, javax.portlet.HeaderPortlet, javax.portlet.Portlet, javax.portlet.PortletConfig, javax.portlet.ResourceServingPortlet

public class DHtmlLayoutPortlet
extends javax.portlet.GenericPortlet

The portlet used to process the request for a ZUML page.

Notes:

• The portlet looks for the path of the ZUML page from the following locations:
  1. From the request parameter called zk_page.
  2. From the request attribute called zk_page.
  3. From the portlet preference called zk_page.
• If not found, it looks for the portlet from the following locations:
  1. From the request parameter called zk_richlet.
  2. From the request attribute called zk_richlet.
  3. From the portlet preference called zk_richlet.
• It is based DHtmlLayoutServlet, so you have to declare DHtmlLayoutServlet even if you want every ZUML pages being processed by this portlet.

To patch the rendering result of a ZK portlet, you can implement PageRenderPatch (and specified it in Attributes.PORTLET_RENDER_PATCH_CLASS).
