Includes OpenGL.Qt MultimediaClasses for audio, video, radio and camera functionality.Qt NetworkClasses to make network programming easier and more portable.Qt QMLClasses for QML and JavaScript languages.Qt Quickdeclarative framework for building highly dynamic applications with custom user interfaces.Qt SQLClasses for database integration using SQL.Qt TestClasses for unit testing Qt applications and libraries.Qt WebKitClasses for a WebKit2 based implementation and a new QML API. See also Qt WebKit Widgets in the add-on modules.Qt WebKit WidgetsWebKit1 and QWidget-based classes from Qt 4.Qt WidgetsClasses to extend Qt GUI with C++ widgets.

Qt Addon Modules

Besides the essential modules, Qt offers additional modules for software developers, which are not part of the release. Here is a short list of add-on modules available.

1.4.QT工程

qt-project wiki:

QT工程是一个社区，是一些热爱QT的人组成的精英团队。每一个热爱QT的人都可以参与到社区中来，为QT的发展做出自己的贡献。

QT工程是一个以开源为动力的组织，为用户做出贡献是工程的根本。其中DIGIA为工程做出了最大的贡献，他也掌握着QT商业版的权限。

There are many companies world-wide,

which make their living out of consultancy and product development using Qt on the various platforms.

There are many open-source projects and open-source developers,

which rely on Qt as their major development library.

It feels good to be part of this vibrant community and to work with this awesome tools and libraries.

Does it make you a better person? Maybe:-)
