qt按字节读取txt文件 遇到空格就设为一个变量

[sheery_coding]

txt文件里每个数据的类型不同，不能按行读取，想按字节读取，遇到空格就设为一个变量，如何实现？文件类似这样

#include <QCoreApplication>
#include <QDebug>
#include <QFile>
#include <QDateTime>
#include <QRegularExpression>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QRegularExpression re("^(\\d\\d\\d\\d)/(\\d\\d)/(\\d\\d)/(\\d\\d):(\\d\\d):(\\d\\d)$");
    QVariantList dataList;
    QFile file("D:/data.txt");
    file.open(QFile::ReadOnly | QFile::Text);

    QTextStream in(&file);
    while (!in.atEnd()) {
        QStringList list = in.readLine().split(' ');
        QVariant var;
        for(const QString &data : list) {
            bool ok = false;
            var = data.toInt(&ok);
            if(ok) {
                dataList <<var;
                continue;
            }
            var = data.toFloat(&ok);
            if(ok) {
                dataList <<var;
                continue;
            }
            if(re.match(data).hasMatch()) {
                var = QDateTime::fromString(data, "yyyy/MM/dd/HH:mm:ss");
                dataList << var;
                continue;
            }
        }
    }

    for(const QVariant &data : dataList) {
        qDebug() << data;
    }

    file.close();

    return a.exec();
}
