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.
SupplyChain is a C++ library that simulates a supply chain. It takes full advantage of concurrent programming and multi-core CPUs without the programmer having to know anything about it. A supply chain consists of two mandatory components: initial producers and final consumers. Apart from these components, a supply chain can include any number of manufacturer nodes. Each node can contain any number of elements of its own type. These elements allow very powerful supply chains to be modeled and constructed.
coastal-qt is a small collection of Qt 4/5 desktop applications built around a small Qt extension library. The library mostly focuses on missing features and services like OSD desktop notifications (with DBUS bindings) and offers some convenience classes for Qt. The current applications include a GUI man page viewer, a search tool, and a desktop user notification service daemon with multicast chat.
The libQtCassandra library is an advanced C++ library used to access Cassandra servers. Unlike the basic Cassadra server interface, this C++ library provides separate objects that handle each level of the server data, i.e. the cluster, contexts, table, rows, and cells. It uses Qt and the Qt style for all the classes, which makes it very easy to use if you already know Qt.
The libQtSerialization library is a Qt extension that makes it easy to serialize your data in a forward and backward compatible way. The library is composed of QWriter and QReader. The writer is straightforward - all you have to do is call a writeTag() function and the data is serialized. The reader is a little more complex as it supports special cases, such as sub-classes (so you can save a tree of classes) and arrays of classes (your tree may be composed of multiple instances of a given object).
