    \title All Modules
    \brief A list of all modules in Qt 5.

    \ingroup classlists

    \brief Qt 5 consists of essential modules, add-on modules, and tools.

    \section1 Qt Essentials

    Qt essentials define the foundation of Qt on all platforms. They are
    available on all supported development platforms and on the tested target
    platforms. They will remain source and binary compatible during Qt 5.

    Essential modules are general and useful for a majority of Qt applications.
    A module that is used for a special purpose is considered an add-on module
    even if it is available on all supported platforms.

    The following table lists the Qt essentials:

    \table 80%
    \header
        \li Module
        \li Description
    \row
        \li \l[QtCore]{Qt Core}
        \li Core non-graphical classes used by other modules.
    \row
        \li \l[QtGui]{Qt GUI}
        \li Base classes for graphical user interface (GUI) components.
            Includes OpenGL.
    \row
        \li \l[QtMultimedia]{Qt Multimedia}
        \li Classes for audio, video, radio and camera functionality.
    \row
        \li \l[QtMultimediaWidgets]{Qt Multimedia Widgets}
        \li Widget-based classes for implementing multimedia functionality.
    \row
        \li \l[QtNetwork]{Qt Network}
        \li Classes to make network programming easier and more portable.
    \row
        \li \l[QtQml]{Qt QML}
        \li Classes for QML and JavaScript languages.
    \row
        \li \l[QtQuick]{Qt Quick}
        \li A declarative framework for building highly dynamic applications
            with custom user interfaces.
    \row
        \li \l[QtQuickControls]{Qt Quick Controls}
        \li Reusable Qt Quick based UI controls to create classic desktop-style
            user interfaces.
    \row
        \li \l[QtQuickDialogs]{Qt Quick Dialogs}
        \li Types for creating and interacting with system dialogs from a
            Qt Quick application.
    \row
        \li \l[QtQuickLayouts]{Qt Quick Layouts}
        \li Layouts are items that are used to arrange Qt Quick 2 based items in
            the user interface.
    \row
        \li \l[QtSql]{Qt SQL}
        \li Classes for database integration using SQL.
    \row
        \li \l[QtTestLib]{Qt Test}
        \li Classes for unit testing Qt applications and libraries.
    \row
        \li \l[QtWebKit]{Qt WebKit}
        \li Classes for a WebKit2 based implementation and a new QML API.
            See also Qt WebKit Widgets in the add-on modules.
    \row
        \li \l[QtWebKit]{Qt WebKit Widgets}
        \li WebKit1 and QWidget-based classes from Qt 4.
    \row
        \li \l[QtWidgets]{Qt Widgets}
        \li Classes to extend Qt GUI with C++ widgets.
    \endtable

    If you use \l qmake to build your projects, the \l{Qt Core} and \l{Qt GUI}
    modules are included by default. To link only against Qt Core, add
    the following line to your \c .pro file:

    \code
    QT -= gui
    \endcode

    On Windows, if you do not use \l qmake
    or other build tools such as \l{CMake Manual}{CMake}, you also need to link against
    the \c qtmain library.

    \section1 Qt Add-Ons

    \e{Qt Add-On} modules bring additional value for specific purposes. These
    modules may only be available on some development platform. Many add-on
    modules are either feature-complete and exist for backwards compatibility,
    or are only applicable to certain platforms. Each add-on module specifies
    its compatibility promise separately.

    The Qt installers include the option of downloading the add-ons. For more
    information, visit the \l{Getting Started with Qt} page.

    The following table lists the Qt add-ons:
