      Especially this is used in many places in public header files:

      #if QT_VERSION >= QT_VERSION_CHECK(6,0,0)

      but QDoc evaluates it to true, sometimes leading to APIs 'from the future' to be documented.

      Case in point:

      http://doc-snapshots.qt.io/qt5-5.6/qquickimageprovider.html
      QQuickImageProvider should have these virtual functions documented:

      QImage QQuickImageProvider::requestImage(const QString &id, QSize *size, const QSize &requestedSize)

QPixmap QQuickImageProvider::requestPixmap(const QString &id, QSize *size, const QSize &requestedSize)

QQuickTextureFactory *QQuickImageProvider::requestTexture(const QString &id, QSize *size, const QSize &requestedSize)

      But QDoc doesn't see the correct versions of the declarations because of the incorrect evaluation for the Qt version check.

        No reviews matched the request. Check your Options in the drop-down menu of this sections header.
