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. The user interface is configurable with XML, and it uses a plugin architecture for extra functionality. It features a wide range of application components like palette, overview, the ability to export to many image and XML formats, copy and paste, drag and drop, rich text labels, database or backend connectivity, and visual complexity management. You can use it to create workflow editors, call graphs, CAD tools, network diagrams, database visualization tools, and more.
Zaval Light-Weight Visual Components Library (LwVCL) is a pure Java alternative to humble AWT-based GUI interfaces for a wide range of platforms, including J2SE, PersonalJava, and others. It can be used on wide range of PersonalJava compatible devices, including Sharp Zaurus, Compaq iPAQ, and top models of mobile phones with the same API, as it is used in J2SE applications.
SpeedDemon is an Open Source Java tool to accelerate your Internet downloads. It works by downloading different parts of a file simultaneously and then recombines them to a location you specify. It also allows you to resume disconnected downloads. If you specify mirror links, SpeedDemon will download the file such that the load on the servers are evenly distributed. It has been designed to support different protocols; support for any protocol can be developed by just implementing an Interface, packing it into a JAR file, and then copying the JAR file into a specific directory.
