ExtJS

1. Introduction

Ext comes from YUI-ext. YUI stands for Yahoo User Interface, 
which is a library that groups several functions with .js extension,
to run under Javascript, the style of Script.aculo.us .
Like Javascript and script.aculo.us, Ext is a client-side framework 
for building dynamic web applications. Currently, the library is 
released by the name Ext under 2.2 version. Scripting with 
this library is called ExtJS. I have to say that "ExtJs" is 
not a real Open source in the sense that everything is just dictated.

2. Getting started ?

To dowload the related library, go to extjs.com
choose Ext JS 2.2 SDK and  dowload ext-2.2.zip.
Unzip the packet in a directory; say C:\ExtJS, to get the "ext-2.2" 
directory. This directoy contains the subdirectory "ext-2.2" which 
includes all the libraries. We can use the "examples" subdirectory to 
get started.

Make a subdirectory as "Examples" within C:\ExtJS\ext-2.2, 
as C:\ExtJS\ext-2.2\Examples and try some examples to remark that 
constraints are well set if we want to use the codes..
