Autopsy of a Widget

Sign up or log in to save this to your schedule and see who's attending!

With modern JavaScript frameworks like ExtJS, SproutCore or qooxdoo, it is possible to create very rich user interfaces using only open web standards. But how do they do it? How do they work internally? In this talk Fabian will open the thorax of a simple qooxdoo widget and look at the various layers and building blocks used to implement it. You will learn how the widget is represented in the DOM, how events are handled, and how the layout engine works. Often there is more than a single way to achieve something. In those cases the different options and qooxdoo's specific design decision will be presented. This talk is targeting everyone interested in building rich user interfaces with JavaScript. We would love to discuss our ideas with JavaScript experts and developers of other frameworks.
