Sencha Learn Roundup

With the preview of Sencha Touch 2 available, it is a great time to explore the APIs and prepare to upgrade your existing applications. In this article from our newsletter, “Upgrading to Sencha Touch 2 PR2”:https://www.sencha.com/learn/upgrading-to-sencha-touch-2-pr2, we take a simple existing example app–the Touch 1 CityBars guide–and explore what is required to make it compatible with the Touch 2 PR2 release.

Following up from his highest-rated SenchaCon talk, Jacky Nguyen prepared a great tutorial on “the Sencha Class System”:https://www.sencha.com/learn/sencha-class-system within Ext JS 4 and Sencha Touch 2. Both frameworks use the classes to manage dependencies, improve reuse, and provide rich features commonly found in class-based languages. Developers writing code using Ext JS 4 and Touch 2 can inherit from internal classes in the frameworks and make their own code object-oriented.

Community member Jay Garcia has posted his own take on the Sencha Touch 2 Class System, which you can find as an 11 minute screencast in this “contributed piece to Sencha Learn”:https://www.sencha.com/learn/sencha-touch-2-class-system.

Tommy Maintz continues his Ext JS 4 MVC series of articles. In the previous two articles, he explored architecting a Pandora-style application using the new features of Ext JS 4. In the third installment, he implements controller logic inside of the application’s MVC architecture. Catch up with Part 1 and Part 2 if you haven’t already. Or go straight to Part 3 of “Architecting Your App in Ext JS 4”:https://www.sencha.com/learn/architecting-your-app-in-ext-js-4-part-3.

Ext GWT 3 Beta is now available! To allow a smooth transition from Ext GWT 2 to 3, Ext GWT lets you include both v2 and v3 components in the same application.

Our newest Ext GWT team member Justin Hickman wrote an interesting article on Ext GWT 3 Declarative Markup with UiBinder. UiBinder support has been one of the major driving factors for many of the API changes in Ext GWT 3.0.

Check out this tutorial for building a Car Store with Ext Designer 1.2 and Ext JS 4. This article takes the previous “car store” sample project, upgrades it to Ext JS 4, while adding new JavaScript charts.
