    Description

      For QTBUG-111051, we'd like to (optionally) make QTextStream final. This clashes with the QtChart's example's inheriting from QTextStream. This code seems to be the only in-tree user that inherits QTextStream.

      ~/Qt/qt5$ git grep --recurse-submodules  -E ' : *(public|private|protected)? +QTextStream'
qtbase/src/corelib/serialization/qtextstream.cpp:        setStatus(atEnd() ? QTextStream::ReadPastEnd : QTextStream::ReadCorruptData); \
qtbase/src/corelib/serialization/qtextstream.cpp:        setStatus(atEnd() ? QTextStream::ReadPastEnd : QTextStream::ReadCorruptData); \
qtcharts/examples/charts/boxplotchart/boxdatareader.h:class BoxDataReader : public QTextStream
qtcharts/examples/charts/candlestickchart/candlestickdatareader.cpp:    : QTextStream(device)
qtcharts/examples/charts/candlestickchart/candlestickdatareader.h:class CandlestickDataReader : public QTextStream
