Need explanation about DefaultFramework Layout

Question

hai friends,
i downloaded the PAR file of the default frame work layout provided by SAP in EP7.the coding is given below
<%@ taglib uri="prt:taglib:com.sap.portal.reserved.layout.TagLibHtmlb" prefix="hbj" %>
<%@ taglib uri="prt:taglib:com.sap.portal.reserved.layout.TagLibLayout" prefix="lyt" %>
<%@ page import="com.sapportals.portal.pb.layout.taglib.variabledef.RunMode" %>
<%
  RunMode pageRunMode = null;
%>
<lyt:template>
<%
pageRunMode = epPageVariables.getRunMode();
if(pageRunMode == RunMode.RUN_TIME){
%>
    <script>
        document.body.style.margin=0;
        document.body.scroll = "no";
    </script>
<%}%>
    <hbj:content id="myContext" >
        <hbj:page title="Portal Page">
            <lyt:container id="frameworkColumn" />
        </hbj:page>
    </hbj:content>
</lyt:template>
<%
if(pageRunMode == RunMode.RUN_TIME){
%>
    <script>
        // Set the Top Level Navigation iView size and position.
        EPCM.raiseEvent("urn:com.sapportals:toplevelnavigation", "Onload", null);
    </script>
<%}%>
in this i understood everything except the EPCM part.they have given the purpose as to set the Top Level Navigation iView size and position.but i want to know how it sets,where is the subscribe event for that.
if anybody knows please help me....
if u have more details about it please send that also...

hai Mr.Venkat,
Tahnks for your reply.
yes i downloaded the "com.sap.portal..layouts.framework.par.bak" only.but i am not using all the jsps available in that.
i am using only "framework.jsp".that also i changed according to my need.i changed only the layout part not the whole thing.And also i dont find any "subscribeevent" relevant to the "raiseevent" presents in tha jsp file.
as u said i searched with the WAandNAVpanel.jsp also but i couldnt find. the subscribe events present in the specified file is not relevant to my raise event i think so.....

Tamil K
