4. Implementing the User Interface

Chapter 4. Implementing the User Interface

The classes making up your user interface should encapsulate their own behavior and appearance. View Components may require data or the occasional method invocation from the outside in order to have something to display or to know they need to change to another visual state. But they should be capable of making those visual transitions themselves once given the input and impetus. When they have something to communicate to the rest of the application, they should do this solely by dispatching events or setting properties and making method invocations on their child components. In the context of a PureMVC application, a View Component should never know anything about the PureMVC framework classes or their subclasses.
