Panwa is a framework based on the Qt toolkit for writing platform independent applications with high quality graphical user interfaces. Panwa applications are meant as a complementary approach to Web applications, and the framework makes it possible to create applications that combine the flexibility of Web applications with the usability advantages of native applications. Therefore, you can see it as an implementation of a "rich thin client".
naarani Personal Access is a Java library to run programs that need to create, design, and access a MySQL database. It features automated managment of user rights, SQL code, table updates/track, data input/user masks, and a plugin to quickly add menu/custom fields management. Table and modules (masks) can be created or updated while debugging (even inside Eclipse) without reloading the program.
The zen Platform is a Java development environment for J2SE/J2EE. It eases and accelerates the Java application development by visual methods (RAD). Complete applications can be modelled in an intuitive fashion without the need for technical expertise. The complexity of Java and J2EE programming is tremendously hidden - reducing the learning curve for Java novices. Java experts are by no means restricted - they may apply their knowledge without limitations. Application flexibility is a core feature of the platform, which is delivered as an Eclipse plugin.
The mission of the Apache Portable Runtime (APR) project is to create and maintain software libraries that provide a predictable and consistent interface to underlying platform- specific implementations. The primary goal is to provide an API to which software developers may code and be assured of predictable if not identical behaviour regardless of the platform on which their software is built, relieving them of the need to code special-case conditions to work around or take advantage of platform-specific deficiencies or features.
libGlass is a scalable set of components that can be used by applications to perform distributed computing. Applications are built by reusing the available components as needed. One of the major goals of Glass is to be a user-friendly framework, not only suitable for new applications, but also for legacy code. This is an important feature, as most available solutions for distributed computing require a substantial amount of rewrite of legacy code.
JUCE is an all-encompassing C++ class library for developing cross-platform applications. It's particularly good for creating highly-specialised user interfaces and for handling graphics and sound. The intended users are developers who are building large, complex applications in C++ and who would like to use just one clean, high-level API rather than a bunch of different libraries for different purposes or platforms. Its features include fully lightweight components with transparency and effects, classes for strings, containers, XML, streams, file handling, messaging, and event queues, vector graphics, a custom font engine, image manipulation, OpenGL support, low-latency audio I/O using CoreAudio, DSound and ASIO, audio buffers and nodes, MIDI file and event manipulation, Internet streams, undo/redo support, and more.
The IberAgents platform is a framework for component development in Java. It has facilities for Web service communication (SOAP), persistence to database or files, and interaction via the Web; thus providing an end-to-end solution for data management. It uses its own SOAP library, so it does not depend on Axis or Apache Soap.
Cymbeline is an Python application server framework that includes functionality such as database and arbitrary object pooling, Web servers (including SSL), a persistent object repository, and a text console. It was originally designed as an administrative shell for an embedded system, but has since morphed into a more general purpose, run anywhere toolkit.
