This article explores the creation of a simulated web browser desktop using the ExtJS framework. A screenshot showcases the resulting interface.

The project demonstrates several key ExtJS features, including a desktop UI, integration with the Google Maps API, and examples of grids, tabs, accordions, and border layouts. These are accessible as desktop items, launched via a double-click. Future enhancements planned include a custom layout manager, AJAX-powered tabs, web forms, window messaging, advanced charting capabilities, and custom theme support.

Getting Started with Your Own ExtJS Desktop

Building a similar application requires downloading the Ext JS Open Source framework from Sencha's website. (Detailed instructions will be added later.)

ExtJS Framework Overview

ExtJS offers a rich set of modern UI widgets, boasting high-performance, scalable grids, trees, menus, and more. Its HTML5 and CSS3 foundation ensures cross-platform compatibility across major browsers (IE 6 , Firefox 1.5 , Safari 3 , Chrome 3 , Opera 9 ). The clean component model simplifies extension and customization. Comprehensive documentation, training, and support resources are available from Sencha. Numerous demos can be found at Sencha's example page. The open-source license is suitable for non-commercial projects; commercial use requires a license. More information can be found on the ExtJS product page and the license page.
