title: ExtJS - multil language with i18n texts
body: <p>I was searching info in the itnernet , and I find some information how to change languages in ExtJS. it is <a href="http://dev.sencha.com/deploy/ext-4.0.0/examples/locale/multi-lang.html?lang=ukr&amp;charset=UTF-8" rel="nofollow">on the dev.sencha.com</a></p>
  
  <p>As I see, they use  <strong>locale/ext-lang-{0}.js files.</strong> </p>
  
  <p>Ok That's great! but I need to <strong>change my own texts too</strong>. For example I have  Ext.MessageBox.alert and I want to get text from properti files.</p>
  
  <p>Is there any way to use i18n files too? <strong>Using  langauge parameter of URL (?lang=en, ?lang=fr) use text-en.properties or text-fr.propertes.</strong></p>
  
  <p>I need a good tutorial link, how to create multi language ExtJS page.</p>
  
  <p>I see <strong>Ext.ux.Localizer</strong> add on. <a href="https://github.com/devotis/Ext.ux.Localizer" rel="nofollow">link</a> but I dont understand how to use it. how to change language :(</p>
  
  <p>thank you.</p>
