We covered how to implement the base of the application we are going to implement throughout this book using the Border layout, and you learned how to implement a Logout button (on the Ext JS side and also on the server side). We also covered the Client Activity Monitor and Session Timeout capabilities.

And finally, you learned how to build a translation component using HTML5 features along with Ext JS, which is able to translate all the labels of the application and also change the preferred language at runtime. You also learned how to use the Ext JS locale support used to translate the framework's messages and labels.

We made a great advance in this chapter regarding the implementation of our application. We created new files and our application is growing. We will continue to create more files and components in the next chapters of this book.

In the next chapter, we will learn how to build a dynamic menu using Accordion panels and trees.
