The Diva GUI framework. This is a simple and extensible application framework that most applications should be able to build on without too much trouble. There are two kinds of class in here:

• GUI components. The GUI portion makes extensive use of Swing widgets. The set of classes of this kind ranges from simple widgets that we needed up to full-featured application frames.
• Document framework classes. These classes provide a set of classes to ease the task of constructing multi-document applications. The document framework uses the model-view-controller architecture to manage the state of the application.

In both cases, we have been careful not to make policy decisions that will impact your ability to customize and extend these classes to suit your own needs. An example: there is no default menu layout, so you are not restricted to using conventional (File, Edit etc) menu layouts if you don't want to. There is, however, a good deal of support for standard menu entries if you choose to use it!
