【qt】分组保存参数到ini配置里

    // 创建一个QSettings对象，用于读写INI文件
    QSettings settings(QApplication::applicationDirPath() + "/config.ini", QSettings::IniFormat);
    settings.beginGroup("Time");
    QDateTime lastRecordedTime = settings.value("lastRecordedTime").toDateTime();
    qDebug() << u8"History Xray OFF Time:" << lastRecordedTime.toString(Qt::ISODate);
    settings.endGroup();

    QDateTime currentTime = QDateTime::currentDateTime();

    if (lastRecordedTime.isValid()) {
        qint64 timeDifference = lastRecordedTime.secsTo(currentTime) / 3600; // 转换为小时
        if (timeDifference > 8) {
            fun1();
        }
    } else {
        fun1();
    }

    settings.beginGroup("Time");
    settings.setValue("lastRecordedTime", currentTime.toString(Qt::ISODate));
    settings.endGroup();
    settings.sync();

分组保存参数到ini配置里使用QSettings 即可

    QString appDir = QApplication::applicationDirPath();
    QString m_paraIniFileName = "para.ini";
    QString paraFilePath = QString("%1/%2").arg(appDir, m_paraIniFileName);
    QSettings *settings = new QSettings(paraFilePath, QSettings::IniFormat);

    settings->beginGroup("group1");//组1
    settings->setValue("count", count);
    settings->endGroup();

    settings->beginGroup("group2");//组2
    settings->setValue("min", min);
    settings->setValue("max", max);
    settings->endGroup();

    settings->beginGroup("StackNumber");//组3
    settings->setValue("number", number);
    settings->endGroup();
    settings->deleteLater();//释放
