While keeping Flex 3 classes intact in the same mx.* packages, the Flex 4 beta introduces the spark.* packages for components, core classes, effects, filters, layouts, primitives, skins, and utils.

The Flex 4 beta provides a new set of components and effects that share many of the same class names as Flex 3 components. To avoid name collisions in MXML, the Flex 4 beta comes with four distinct namespaces: MXML 2006, MXML 2009, Spark, and Halo.

MXML 2006: The legacy MXML language namespace used in previous versions of Flex. Flex 3 applications compiled using Flex 4 beta can continue using this namespace.

URI: http://www.adobe.com/2006/mxml

Default Prefix: mx

MXML 2009: The new MXML language namespace. This is purely a language namespace, and does not contain component tags.

URI: http://ns.adobe.com/mxml/2009
Default Prefix: fx

Spark: This namespace includes all of the new Spark components. It should be used in conjunction with the MXML 2009 language namespace.

URI: library://ns.adobe.com/flex/spark
Default Prefix: s

Halo: This namespace includes all of the Halo components. It should be used in conjunction with the MXML 2009 language namespace.

URI: library://ns.adobe.com/flex/halo
Default Prefix: mx

Here is a small example that uses the MXML 2009, Spark, and Halo namespaces to create a simple Flex 4 beta application. This sample uses a Halo DateChooser and a Spark Button.

<s:Application
  xmlns:fx="http://ns.adobe.com/mxml/2009"
  xmlns:s="library://ns.adobe.com/flex/spark"
  xmlns:mx="library://ns.adobe.com/flex/halo">

    <mx:DateChooser id="main_calendar" x="20" y="20"/>
    <s:Button label="submit" x="220" y="20"/>
 
</s:Application>

Flex 4 beta has also added multiple namespace support in CSS. If you are using the MXML 2009, Spark, and Halo namespaces along with Type selectors, you will need to define a set of namespaces in your CSS definitions to avoid name collisions.

Here is an example of CSS that uses type selectors for both Halo and Spark components:

<fx:Style>

    @namespace s "library://ns.adobe.com/flex/spark";
    @namespace mx "library://ns.adobe.com/flex/halo";

    s|Button {
        color: #FF0000;
    }

    mx|DateChooser {
        color: #FF0000;
    }

</fx:Style>

下面是一些关于Flex 4 和Flash Builder 4的一些文档：

What’s new in Flex 4 SDK beta

Public beta of Flex 4 and Flash Builder 4 on Adobe Labs.

You should probably start by reading the introductions from Flex Product Managers:

• Matt Chotin’s intro to Flex 4
• Tim Buntel’s intro to Flash Builder 4

There is a fairly rich set of beta documentation.

• Using Adobe Flex 4 (PDF) – Flex SDK and Framework usage content. This book combines the Flex Developer’s Guide, Creating and Extending Flex Components, and Building and Deploying Flex Applications. Needless to say, the PDF of this content is huge (36Mb)!
• Using Adobe Flash Builder 4 ((PDF)) – Flash Builder usage content
• Adobe Flex 4 Tutorials (PDF) – Tutorials to help you get started with new Flex 4 and Flash Builder 4 features.
• Creating Data-Driven Applications with Adobe Flex 4 (PDF)- Usage content for data access in Flex. Includes information on new Flash Builder data service features.
• Adobe Flex 4 Feature and Migration (PDF-only)
• Flex 4 ActionScript Language Reference

Also, some of the developers created videos and they really turned out well. You can check these out, too. They live under http://labs.adobe.com/technologies/flashbuilder4/tutorials

And finally, if you really want background information, there are updated specs on opensource.adobe.com:

• IGraphicElement spec
• Horizontal & Vertical Layout
• Basic Layout
• DataGroup
• Group
• SkinnableDataContainer
• SkinnableContainer
• VideoPlayer

网上的十本关于Python的免费的完整的在线阅读书籍。

Dive into Python

几乎涵盖了所有的方面，包括从Python安装，到Web Services再到单元测试等等。还有简体中文版本在线阅读。

This is a fantastic book that is also available in print. It covers everything, from installing Python and the language’s syntax, right up to web services and unit testing. This is a good book to learn from, but it’s also excellent to use a reference. I frequently find myself visiting the site! If you only read one book on this list make it this one.

在arnotify  发表了一篇 Writing well-behaved, efficient, AIR applications 的文章，阐述了一些关于在开发AIR程序中遇到的资源占用过高情况的解决方案。总体来看，作者解决的出发点是在对程序的FrameRate的控制上。在AIR程序中经常会遇到资源占用严重的问题，也许你可以从这篇文章中寻找到一些解决灵感。

怎样解决你的应用资源占用过高，怎样优化你的程序？你可以从下面几个方面尝试一下：

1. Use the lowest framerate possible –>尽量降低你程序的帧频，当然前提是在不影响你程序的流畅表现的情况下，一般的程序设置是24fps，但是在很多的AIR应用中，根本不需要这么多，你可以设置你的mx:WindowedApplication中的frameRate属性，或者在你的ActionScript中的stage.frameRate (Read more…)
