In Ext GWT 2, component styles were defined in a single large CSS file. Developers could extend or redefine the styles in this file to control the appearance of a component or define a custom theme. Although this made it easy to give components a new look, it was hard to determine the relationship between the styles in the CSS file and the components in the library. Furthermore, there was no assurance that all of the styles in the CSS file were needed, or that the styles needed for a particular component were actually defined in the CSS file.
Extensions provide developers with valuable features beyond those that ship in Sencha’s frameworks, and are a very important part of the Sencha platform. At Sencha, we are investing to improve the ecosystem of extensions on our platform and I wanted to share an early look at our progress.
In a previous article, we discussed the charting library as a whole. However, there is far more to the Sencha GXT 3 charting library than was covered in that introduction. This article discusses a number of the more intermediate and advanced features that you can use — including tweaking the data store backing your chart. With some simple changes to the basic chart setup, you can make your visualizations even more explanatory and expressive.
We’re excited to announce the general availability of Sencha GXT 3.0! Sencha GXT, previously known as Ext GWT, is our Java based web application framework that leverages the Google Web Toolkit compiler. With the Sencha GXT 3.0 framework, developers can build high performance web applications with cross-browser compatibility across all desktop browsers.
The Ext GWT 3.0 State API provides the ability to persist state information. The API supports saving state data to different persistence providers. These include providers based on cookies and HTML5 local storage. The data are saved and retrieved as a map from string keys to string values. State data are serialized to strings and deserialized to objects via the bean-like interfaces of GWT AutoBeans. This data is retrieved asynchronously, and this allows for asynchronous providers such as those that communicate via RPC.

As a result, we are closing in on being feature complete.
It has always been a challenge to draw objects in GWT because SVG and VML are not supported out of the box. In Ext GWT 3.0, we solve this problem by providing a draw framework that runs everywhere, from IE6 to the latest Chrome that is developed as a pure GWT library.
Today we are excited to announce Ext GWT 3 Developer Preview 2. This release features the long awaited UiBinder support, new container and layout architecture, and a raft of bug fixes and general improvements.
