Bongo is the new Java-based graphical interface design and development product from Marimba, Inc. - the hot Silicon Valley startup founded by four original members of the Sun Java team. Just as Marimba's Castanet technology is changing the way Java applications are distributed, Bongo is changing the way Java applications are developed, enabling programmers and application designers of all skill levels to quickly create a user interface to a Java application using a variety of predesigned widgets, images, audio, and animation. With this book you'll learn how Bongo fits into Marimba's Castanet product strategy, and how to use it to create your own presentations and Castanet channels. It covers all aspects of Bongo use, from building simple interfaces with existing components, to blending Java programs with your presentations, to extending Bongo by programming your own widgets. Whether you're a casual Java programmer, an experienced Java developer, or an application interface designer, the Official Marimba Guide to Bongo provides all you need to quickly learn how to use Bongo.
