Why pSerialPortQPlainTextEdit showed slow I think QT is bug ????



  • QElapsedTimer timer;
    timer.start();
    pSerialPortQPlainTextEdit.insertPlainText(DatatFormRead);
    pSerialPortQPlainTextEdit.moveCursor(QTextCursor::End, QTextCursor::KeepAnchor);
    qDebug() << "The slow operation took" << timer.nsecsElapsed() <<"nanoseconds";
    test result:
    The slow operation took 1017500 nanoseconds
    The slow operation took 1018310 nanoseconds
    The slow operation took 1421502 nanoseconds
    The slow operation took 1186476 nanoseconds
