    \title Qt Deprecation Macros

    \brief The <QtDeprecationMarkers> header file contains deprecation helper macros.

    The header file declares several macros for disabling deprecated Qt APIs
    and enabling/disabling compiler warnings when they are used.
*/

/*!
    \macro QT_DISABLE_DEPRECATED_BEFORE
    \relates <QtDeprecationMarkers>
    \deprecated [6.5] Use QT_DISABLE_DEPRECATED_UP_TO instead

    \sa QT_DISABLE_DEPRECATED_UP_TO
*/

/*!
    \macro QT_DISABLE_DEPRECATED_UP_TO
    \relates <QtDeprecationMarkers>

    This macro can be defined in the project file to disable functions
    deprecated in a specified version of Qt or any earlier version. The default
    version number is 5.0, meaning that functions deprecated in or before
    Qt 5.0 will not be included.

    For instance, when preparing to upgrade to Qt 6.3, after eliminating all
    deprecation warnings, you can set \c{QT_DISABLE_DEPRECATED_UP_TO=0x060300}
    to exclude from your builds the Qt APIs you no longer use. In your own
    project's build configuration, this will ensure that anyone adding new calls
    to the deprecated APIs will know about it right away. If you also build Qt
    for yourself, including this define in your build configuration for Qt will
    make your binaries smaller by leaving out even the implementation of the
    deprecated APIs.

    \sa QT_DEPRECATED_WARNINGS, QT_DISABLE_DEPRECATED_UP_TO
*/

/*!
    \macro QT_DEPRECATED_WARNINGS
    \relates <QtDeprecationMarkers>

    Since Qt 5.13, this macro has no effect. In Qt 5.12 and before, if this macro
    is defined, the compiler will generate warnings if any API declared as
    deprecated by Qt is used.

    \sa QT_DISABLE_DEPRECATED_UP_TO, QT_NO_DEPRECATED_WARNINGS
*/

/*!
    \macro QT_NO_DEPRECATED_WARNINGS
    \relates <QtDeprecationMarkers>
    \since 5.13

    This macro can be used to suppress deprecation warnings that would otherwise
    be generated when using deprecated APIs.

    \sa QT_DISABLE_DEPRECATED_UP_TO
