    \title All Modules
    \brief A list of all modules in Qt 6.

    \ingroup classlists

    \brief Qt 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. Except the testing modules, which will remain source compatible,
    these modules will remain source and binary compatible throughout Qt 6.

    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}

    \row
        \li \l[QtDBus]{Qt D-Bus}
        \li Classes for inter-process communication over the D-Bus protocol.
    \row
        \li \l[QtGui]{Qt GUI}
        \li Base classes for graphical user interface (GUI) components.
    \row
        \li \l[QtNetwork]{Qt Network}
        \li Classes to make network programming easier and more portable.

            with custom user interfaces.
    \row \li \l{Qt Quick Controls}
         \li Provides lightweight QML types for creating performant user
             interfaces for desktop, embedded, and mobile devices. These
             types employ a simple styling architecture and are very efficient.
    \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[QtQuickTest]{Qt Quick Test}
        \li A unit test framework for QML applications, where the test cases
            are written as JavaScript functions.
            \note The binary compatibility guarantee does not apply to Qt Quick
                  Test. However, it will remain source compatible.
    \row
        \li \l[QtTestLib]{Qt Test}
        \li Classes for unit testing Qt applications and libraries.
            \note The binary compatibility guarantee does not apply to Qt Test.
                  However, it will remain source compatible.
    \row
        \li \l[QtWidgets]{Qt Widgets}
        \li Classes to extend Qt GUI with C++ widgets.
    \endtable

    \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:
