Hi, i'm also new in ExtJS but i'm Reading 'learning ExtJS' book it's awesome you should read it if u like have control with ExtJS library.
In order to let your project use ExtJS, you shout add these files and folder to your lib directory :
- adapter and resources folders
- ext-all-debug.js at production step (when writing your code it's help you have some error codes and give you some informations about errors on your code)
- ext-all.js when your code is ready to be published, change the ext-all-debug.js file by this one after your code is clear and your app running
now you should insert some links into your index file like :
IE: in this code i add resources, adapter folder and ext-all-debug.js file in a folder named "extjs" under lib folder.
<link rel="stylesheet" type="text/css" href="lib/extjs/resources/css/ext-all.css" />
i hope give you some help
