Testing Ext JS & Ext GWT Applications With Selenium

Darrell Meyer — Mon, 03 Nov 2008 18:21:50 +0000

Selenium provides a powerful mechanism to test your Ext applications. Selenium works by executing tests against your running application within the browser of your choice. Selenium tests emulate the way a user would interact with your application by executing JavaScript to simulate user actions. Selenium tests run as a form of "integration" tests as they execute against your running application.

Extending Reader and Proxy - An Ext Flickr Image Gallery

Evan Trimboli — Fri, 17 Oct 2008 04:25:48 +0000

Retrieve data from Yahoo's Flickr service to create an engaging an Ext Image Gallery powered by Flickr's latest images. Flickr is a popular image sharing management tool that allows users to create online photo albums and tag photos. By extending Ext's native data package we can pull this data directly into Ext's data Store to drive an Ext Image Gallery component capable of searching and paging through the results.

Ext Charting and Mapping with Google Visualizations

Aaron Conran — Mon, 13 Oct 2008 07:43:43 +0000

Creating cross-browser consistent visualizations of data without Adobe's Flash plugin has always been a difficult issue to address. Google introduced a Visualization API earlier this year which enables you to present tabular data in the form of charts, maps, and other graphical representations without the need for Flash. (Some visualizations actually do use flash, but most are implemented with SVG and/or VML.) Working with different API's can present hurdles as we attempt to massage the same data in two different data structures - one for a grid and another for a pie chart. To address this specific challenge, I developed a short user extension Ext.ux.GVisualizationPanel enabling users to integrate visualizations into Ext JS applications without concern for these issues. The GVisualizationPanel adapts any Ext data Store into the google's format and enables you to embed any type of visualization into a panel.

Ext GWT Grid Performance Improvements

Darrell Meyer — Mon, 29 Sep 2008 04:17:33 +0000

The Ext GWT Grid component, which was introduced in 1.1, plays an important role in most applications. Because of this, it is important for Grid to perform as fast as possible, especially when rendering large amounts of data. For the upcoming 1.1.1 release we took a fine grained look at the code and were able to lower rendering times significantly.

Improving Application Usability with Ext JS Keyboard Handling

Rich Waters — Tue, 23 Sep 2008 23:16:11 +0000

As Enterprise applications begin moving to the web instead of the desktop many developers may forget about providing key bindings for their applications. Most web applications use the keyboard only for text entry and do not associate particular key combinations with user actions. By providing this type of key handling, particularly for applications which require a lot of data entry, we can improve the end-user experience.

Ext JS at The Ajax Experience

Aaron Conran — Mon, 15 Sep 2008 14:24:30 +0000

Come join Jack Slocum and I for two developer focused sessions, "Hands On Ext" and "Advanced CSS and Theming of Ext JS" at The Ajax Experience at the end of this month. Feel free to follow along with your laptop or watch as we build an application and demonstrate how to create a custom theme in each hour long session. The Ajax Experience is a three day conference with many interesting sessions on Ajax, Web 2.0 technologies and JavaScript frameworks targeted at developers.

Google Contacts: Creating a Google Chrome App with Ext and the Google Data API

Jamie Avins — Tue, 09 Sep 2008 17:01:10 +0000

When Google Chrome was released last week, I was interested in seeing how the Application mode feature worked. I revived an old project to interface with the Google Contacts Data API and built a small application to manage your google contacts which you can 'install'. The example extends the Ext.data.DataProxy to allow you to populate a store with your contact information to bind to any store driven components such as Grid, EditorGrid, ComboBox and DataView.
