说明：  Eclipse中使用SWT进行界面设计 SWT是一个IBM开发的跨平台GUI开发工具包。至于为什么IBM要费劲自己另起炉灶开发一个GUI工具包，而不是使用Sun现有的由AWT, Swing, Java 2D, Java 3D等构成的Java GUI框架，那就说来话长了。
(Eclipse SWT used for interface design IBM SWT is a cross-platform development of the GU I development kit. As to why IBM to the grueling out with its own GUI development of a tool kit, rather than using the existing Sun from AWT, Swing, Java 2D, Java 3D components of the Java GUI framework, it had a long history.)
