QWebSockets is a pure Qt implementation of WebSockets, both client and server. It is implemented as a Qt source code module (.pri file) which can easily be embedded into existing Qt projects. It has no dependencies other than Qt. It features text and binary sockets, frame-based and message-based signals, proxy support, and strict Unicode checking.
Voreen is a rapid application development framework for the interactive visualization and analysis of multi-modal volumetric data sets. It provides GPU-based volume rendering and data analysis techniques and offers high flexibility when developing new analysis workflows in collaboration with domain experts. The Voreen framework consists of a multi-platform C++ library, which can be easily integrated into existing applications, and a Qt-based stand-alone application.
Into is a cross-platform machine intelligence application framework written in C++. Into provides a different, fast way to build high-performance applications for image analysis, machine vision, pattern recognition, and artificial intelligence. It features a layered API and more than 20 fully interoperable plug-in modules for accessing image and data sources, powerful feature extractors, classifiers, neural networks, and much more. It also provides Ydin, an innovative execution engine that makes it easy to create dynamic programs that automatically run in parallel, enabling you to create more with less hassle, less code, and less time. Into uses Qt to let you create beautiful user interfaces for your applications with ease.
Herqq UPnP (HUPnP) is a software library for building UPnP devices and control points conforming to the UPnP Device Architecture version 1.1. It is designed to be simple to use and robust in operation. It is built using the Qt framework, following many of the design principles and programming practices used in the Qt framework. It integrates into Qt-based software smoothly and enables truly rapid UPnP development.
The QtLua library aims to make Qt 4 applications scriptable using the Lua scripting language. It is an alternative to the QtScript module. QtLua does not generate or use generated binding code for Qt. Instead it provides useful C++ wrapper classes to make C++ and Lua objects accessible from both Lua and C++. It takes advantage of the Qt meta object system to expose QObject members to Lua scripts and comes with user manual and examples.
