The Frozen Canuck is at it again.  This time with I think the first public explanation of how to build a custom view with the new SC.View class. Notice that SproutCore 1.0 views are built using a simple render() method where you generate HTML.  It’s a really easy API and it just so happens to be extremely fast, especially in IE where DOM manipulation is very expensive.

Aspect-Oriented Programming and You

One of the coolest parts of the new SproutCore View layer is its ability to use aspect-based programming to add behaviors to views. Aspect-based programming is built on the premise that often objects that don’t follow from the same class hierarchy may in fact need similar behaviors. This is especially true in GUI programming when designers come to you and say something like “I came up with this new widget - it looks kind of like a progress bar but it acts like a button when you click on it”. In SproutCore, you capture these common behaviors in a “mixin”.  A mixin is just a colle... (more)

“From where we sit now, the code is shaping up quite nicely. Soon enough, if you have a SproutCore app, you’ll be able to just drop an editor right into your app. As of today, anyone with a website can grab a copy of Bespin and include the editor component very simply in their pages. We figure that we’ve got another month of work to do before we’re ready to update bespin.mozilla.com. We have a whole bunch of features to port over from the old code and we need to make good on another big part of the Reboot promise: opening Bespin up for plugins. It’s been hard even for Bespin core... (more)

The Next Revolution

Every so often a few technology trends converge that yield results much greater than their individual parts.  I think we have reached one of those moments with mobile devices (like the iPad) and HTML5. In many ways, the iPad is the perfect web device.  It’s a lean-back experience optimized around consuming content. With HTML5 (which mobile Safari does better than just about anything else), the kind of experience you can create on these devices is just really spectacular. You only need to use the NPR demo we wrote earlier this year for a few minutes to realize this is obviously t... (more)

Get Time Tracker Source Code in SproutCore

SOA & WOA Magazine Bruz Marzolf is writing a series of blog posts implementing a simple time tracking app in various client-side rich web app frameworks. He just finished his example in SproutCore and including some source code. Here’s what he had to say: SproutCore provides a higher level abstraction that manages when objects are changed and need to be updated, and when they’re busy and shouldn’t be modified, for instance. Bruz’ code is a good example of a basic starter app that’s a little more complex than our todos demo. I’m looking forward to his additional entries in this s... (more)
