We are very proud to announce the final release of Ext Core under the MIT license. Your feedback was invaluable. Thank you for all the bugs reported and test cases created. For those of you who are new to Ext Core, we suggest you read the previous blog post about the all the features and examples that we released as part of the beta.
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.
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.
