JClass BWT is a GUI toolkit which extends and enhances the standard Java GUI toolkit (AWT) included with the Java Developer Kit (JDK). As experienced Java developers already know, developing GUI applications with Java is a time consuming and often frustrating task. There are any number of problems associated with AWT, from the lack of an effective API to problems running applications across platforms. BWT solves the problems associated with AWT by providing a collection of controls that is a superset of the components and the functionality provided in the standard toolkit. To address the problem of creating high quality cross platform applications, BWT implements a “peerless” user interface, meaning that BWT components look and feel the same way on any platform – from Windows to Macintosh to Motif. BWT solves the developer productivity problem by providing a rich API with dynamically controllable properties.
