-    \macro QT_VERSION_CHECK(major, minor, patch)
-    \relates <QtGlobal>
-
-    Turns the \a major, \a minor and \a patch numbers of a version into an
-    integer that encodes all three. When expressed in hexadecimal, this integer
-    is of form \c 0xMMNNPP wherein \c{0xMM ==} \a major, \c{0xNN ==} \a minor,
-    and \c{0xPP ==} \a patch. This can be compared with another similarly
-    processed version ID.
-
-    Example:
-
-    \snippet code/src_corelib_global_qglobal.cpp qt-version-check
-
-    \note the parameters are read as integers in the normal way, so should
-    normally be written in decimal (so a \c 0x prefix must be used if writing
-    them in hexadecimal). Thus \c{QT_VERSION_CHECK(5, 15, 0)} is equal to \c
-    0x050f00, which could equally be written \c{QT_VERSION_CHECK(5, 0xf, 0)}.

-    \macro QT_VERSION
-    \relates <QtGlobal>
-
-    This macro expands to a numeric value of the same form as \l
-    QT_VERSION_CHECK() constructs, that specifies the version of Qt with which
-    code using it is compiled. For example, if you compile your application with
-    Qt 6.1.2, the QT_VERSION macro will expand to \c 0x060102, the same as
-    \c{QT_VERSION_CHECK(6, 1, 2)}. Note that this need not agree with the
-    version the application will find itself using at \e runtime.
-
-    You can use QT_VERSION to select the latest Qt features where available
-    while falling back to older implementations otherwise. Using
-    QT_VERSION_CHECK() for the value to compare with is recommended.

-
-    \snippet code/src_corelib_global_qglobal.cpp 16
