Spark Component Architecture
This section describes the Spark component architecture introduced in Flex 4 to replace the MX component architecture in previous Flex versions.
The biggest change to Flex 4 is the introduction of
a new skinning and component architecture called Spark.
According to Adobe document, Spark is introduced to meet these goals:
- Define a clean separation between the functional logic of the component and its appearance.
- Create a small set of basic components that are easily customized by developers.
- Implement the Spark components on the same base classes as the components in the previous versions of Flex.
The Spark component architecture is represented as:
- spark.* class packages in the ActionScript API.
- library://ns.adobe.com/flex/spark namespace in the MXML API.
Flex 4 offers a default component container called "Application" in the Spark component architecture.
The "Application" container has a default size of 375x500 pixels and a default frameRate of 24 fps.
To use "Application" container in ActionScript API, you can extend a sub class
from spark.components.Application class.
To use "Application" container in MXML API, you can use the Spark Application element:
