Re: How to write a custom layout?

[Elif Guner]

Hi David,
Thanks for your quick response. One more thing I'd like to ask is that
where can I find that portlet.xml if I want to edit it myself? I built
a custom portal using maven plugin.
Thanks again...

Layouts are implemented as portlets.
There is currently one portlet application for all layouts.
I think we need to improve on this solution, because everytime we need a
new column layout, we need to define a new portlet. I checked in a
change to the portlet.xml for the layout portlets. Here it is;

<portlet id="VelocityFourColumns">
     <portlet-name>VelocityFourColumns</portlet-name>
     <display-name>Four Layout Using Velocity</display-name>
     <init-param>
       <name>ViewPage</name>
       <value>columns</value>
     </init-param>
     <init-param>
       <name>MaxPage</name>
       <value>maximized</value>
     </init-param>
     <init-param>
       <name>columns</name>
       <value>4</value>
     </init-param>
     <init-param>
       <name>sizes</name>
       <value>20%,30%,30%,20%</value>
     </init-param>
     <init-param>
       <name>layoutType</name>
       <value>FourColumns</value>
     </init-param>

<portlet-class>org.apache.jetspeed.portlets.layout.MultiColumnPortlet</portlet-class>

<resource-bundle>org.apache.jetspeed.portlets.layout.resources.LayoutResource</resource-bundle>
     <expiration-cache>-1</expiration-cache>
     <supports>
       <mime-type>text/html</mime-type>
       <portlet-mode>view</portlet-mode>
       <portlet-mode>edit</portlet-mode>
       <portlet-mode>help</portlet-mode>
     </supports>
     <portlet-info>
       <title>VelocityFourColumns</title>
       <short-title>FourColumns</short-title>
     </portlet-info>
</portlet>



Here is a sample psml file using the four column layout:

<?xml version="1.0" encoding="UTF-8"?>
<page id="/Test.psml" hidden="false">
     <title>Test</title>
     <short-title>Test</short-title>
     <defaults layout-decorator="tigris" portlet-decorator="tigris"/>
     <fragment id="P-10da7f576ef-10001" type="layout"
name="jetspeed-layouts::VelocityFourColumns">
         <fragment id="P-10da7f62ec0-10002" type="portlet"
name="demo::BookmarkPortlet">
             <property name="row" value="0"/>
             <property name="column" value="0"/>
         </fragment>
         <fragment id="P-10da7f62ec0-10003" type="portlet"
name="demo::CustomerDetail">
             <property name="row" value="1"/>
             <property name="column" value="2"/>
         </fragment>
         <fragment id="P-10da7f62ede-10004" type="portlet"
name="demo::CustomerInfo">
             <property name="row" value="1"/>
             <property name="column" value="3"/>
         </fragment>
         <fragment id="P-10da7f62ede-10005" type="portlet"
name="demo::CustomerList">
             <property name="row" value="0"/>
             <property name="column" value="1"/>
         </fragment>
     </fragment>
</page>
