Visual Oberon is an object-oriented library for writing portable GUI programs in X or Win32. It contains an extensive set of widgets with configurable look-and-feel. Visual Oberon implements the Model-View concept: several visible widgets can reflect a single internal model, and are automatically updated when the state of the model changes.
Uncle Unc is a framework for working with trees of objects. Existing services such as filesystems, code libraries, networks, log files, mailboxes and directories can be mapped onto this object tree, as can some traditional desktop applications. User interfaces work directly with the object tree, offering best of breed interface design (e.g. filtering, breadcrumb bars, paging, sorting, and file-explorer-like views) across the full range of services. The framework promotes clean design, completeness of representation, and reusability of both front end and back end code.
JGraphpad Pro is a complete application framework for rapid development of JGraph tools. It is meant for developers who wish to provide a stand-alone, rich-client graph application.
