Trying to extend a Panel

[inhib]

Hi,

Still beginner with Extjs, I'm trying to extend a Panel :

I want to open multiple times the same panel in tabs. So I think I need to create my class wich extends a panel with my items, grids, combos, datasources inside.

Maybe I'm wrong, but I think I should have that :

MyDesktop.Article.MyArticle= Ext.extend(Ext.Panel,{
title:'mytitle',
layout:'column',
items:[columnOne,columnTwo]
})

The problem is that I don't know how to declare my Datasources, my combos, grids, and even my columnOne and columnTwo.
Inside a initComponent:function() ?

Thanks for any help

MyDesktop.Article.MyArticle= Ext.extend(Ext.Panel,
{
   title:'mytitle',
   layout:'column',

   initComponent: function()
   {
      Ext.apply(this,
      {
         items: [item1, item2]
      }
      );
      MyDesktop.Article.MyArticle.superclass.initComponent.call(this);
   }
}
);
