Inqlude provides a comprehensive listing of all existing libraries for developers of applications using the Qt toolkit. Inqlude is run by the community and open for contributions.
Framework for embedding Lua in Qt applications
The QtLua library aims to make Qt4/Qt5 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 advantages of the Qt meta object system to expose QObject members to lua scripts.
QtLua is not designed to develop an application in pure Lua but rather to extend a Qt C++ application using Lua as scripting language.
