  function without annoying a user who needs to stay compatible with a specified minimum
  version and therefore can't use the new function.

/*
    QT_IF_DEPRECATED_SINCE(major, minor, whenTrue, whenFalse) expands to
    \a whenTrue if the specified (\a major, \a minor) version is less than or
    equal to the deprecation version defined by QT_DISABLE_DEPRECATED_UP_TO,
    and to \a whenFalse otherwise.
 
    Currently used for QT_INLINE_SINCE(maj, min), but can also be helpful for
    other macros of that kind.
 
    The implementation uses QT_DEPRECATED_SINCE(maj, min) to define a bunch of
    helper QT_IF_DEPRECATED_SINCE_X_Y macros, which expand to \a whenTrue or
    \a whenFalse depending on the value of QT_DEPRECATED_SINCE.
 
    If you need to use QT_IF_DEPRECATED_SINCE() for a (major, minor) version,
    that is not yet covered by the list below, you need to copy the definition
    and change the major and minor versions accordingly. For example, for
    version (X, Y), you will need to add
 
    \code
    #if QT_DEPRECATED_SINCE(X, Y)
    # define QT_IF_DEPRECATED_SINCE_X_Y(whenTrue, whenFalse) whenFalse
    #else
    # define QT_IF_DEPRECATED_SINCE_X_Y(whenTrue, whenFalse) whenTrue
    #endif
    \endcode
