Qt遍历整个ini，读取ini，写ini

遍历整个ini

	QSettings *machine_data = new QSettings("/home/u/cnc/configs/ppmc/xxx.ini",QSettings::IniFormat);
    machine_data->setIniCodec("UTF-8");
	QStringList str = machine_data->allKeys();
    qDebug() <<"allKeys : " << str << endl;

    foreach(QString key,str)
    {
        qDebug() << machine_data->value(key).toString()<< endl;// 读取 savePath 的值
    }

读取ini

    int flag;
    QSettings *machine_data = new QSettings("/home/u/cnc/configs/ppmc/xxx.ini",QSettings::IniFormat);
    machine_data->setIniCodec("UTF-8");
    machine_data->beginGroup("BigGroup");
    gpib_kaiguan=machine_data->value("ChildKey").toInt();
    machine_data->endGroup();
    delete machine_data;

写ini

    int flag=1;
    QSettings *machine_data = new QSettings("/home/u/cnc/configs/ppmc/xxx.ini",QSettings::IniFormat);
    machine_data->setIniCodec("UTF-8");
    machine_data->beginGroup("BigGroup");
    machine_data->setValue("ChildKey",flag);
    machine_data->endGroup();
    delete machine_data;
