In my last post I introduced event delegation in SproutCore and the basics of how to handle events.   In this post I’m going to build on this foundation to show you how you can add event handlers to drag a view around the window.* Introducing the Mouse Events As I noted in the first post, SproutCore recognizes several different types of mouse events.  Most of these events are essentially the same events sent by most browsers, though some differ significantly in order to give you tighter control. Remember that to listen for events, you just need to add a method to your view with the same name.  Here is a quick rundown of the different methods you can add to your view: mouseDown() - Called when the mouse button is pressed while over your view.   You must return YES (i.e. true) from this method for mouseDragged() or mouseUp() to be called. mouseDragged() - Called when t...

"From where we sit now, the code is shaping up quite nicely. Soon enough, if you have a SproutCore..."

“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)

Memory Optimization By @SproutCore | @DevOpsSummit [#DevOps]

The next release candidate for 1.11.0 will be out very shortly, but I thought it best to post a brief update on the past week’s work as this week saw a concentrated effort on core optimization. First we took another look at the use of arguments lists throughout the framework and found several more occurrences of it being accessed in an inefficient manner. Depending on the browser, accessing arguments in such a way that causes it to be allocated can be up to 80% slower and so it’s really good to have these all fixed. The other piece of optimization work undertaken has been much mo... (more)

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)

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)
