深入观察Rich Clients, Java与Eclipse

Milinkovich: With rich-client platforms you can build user interfaces in Swing, with roots. So, rich-client platform is not about SWT. I mean it does support SWT out of the box, obviously, and the Swing support is only currently working on Windows and Linux, so we still have some work to do. That's why I said in terms of being able to provide a plug-in application, plug-in architecture for developers who are building rich-client applications, being able to have an update manager so you can find other plug-ins and new functionality, to have a generic workbench so you have an abstraction you can plug your other applications into and you can brand for your corporation. Those, to my mind, are all interesting features.

Q: Can you expand on your comments and update us on what Eclipse is doing in the rich client area?

Milinkovich: The main benefits of RCP [Rich Client Platform] include:

• RCP provides a pre-built, extensible, well-designed architecture that allows developers to immediately begin working on adding application functionality rather than on building infrastructure. When building desktop applications on the Eclipse RCP, a development team can quickly begin designing end-user functionality, and delivering it. Without the RCP, they need to talk about window management, toolbar management, menu management, and get solutions for these and other basic infrastructure issues in place before they can really build an application.
• The ability to create rich user interfaces for client-side applications using SWT and JFace. Developers can deliver rich client applications written in Java, which are essentially indistinguishable from native applications written in languages such as C/C /C#. But at the same time, these applications are portable across all supported platforms.
• The ability to provide a managed code environment that is not browser-based. With RCP, developers can provide a desktop environment that is packaged to link to a server-based update manager. This provides the ability for end users to discover new and updated functionality and apply it to their desktop environments. At the same time, system administrators can be confident that they can control what is deployed on the managed desktops.
• The ability to create, manage, and brand desktop applications using the GenericWorkbench allows entERPrise developers to create a well-defined end-user environment to which they can deploy new applications.
