Qt对ini文件的读写

研究了以下Qt下ini文件的读写，不废话，上干货。

写入ini文件

WriteIni.cpp

 void WriteIni::writeSettings()

 {

     QSettings settings("config.ini", QSettings::IniFormat); // 当前目录的INI文件

     settings.beginGroup("mountinfo");

     settings.setValue("mount",);

     settings.endGroup();

     settings.beginGroup("v");

     settings.setValue("v1",14.2);

     settings.setValue("v2",14.3);

     settings.setValue("v3",14.4);

     settings.setValue("v4",14.5);

     settings.setValue("v5",14.6);

     settings.setValue("v6",14.8);

     settings.endGroup();

     settings.beginGroup("a");

     settings.setValue("a1",2.0);

     settings.setValue("a2",2.1);

     settings.setValue("a3",2.2);

     settings.setValue("a4",2.3);

     settings.setValue("a5",2.4);

     settings.setValue("a6",2.5);

     settings.endGroup();

     settings.beginGroup("p");

     settings.setValue("p1",);

     settings.setValue("p2",);

     settings.setValue("p3",);

     settings.setValue("p4",);

     settings.setValue("p5",);

     settings.setValue("p6",);

     settings.endGroup();

     settings.beginGroup("j");

     settings.setValue("j1",4.8);

     settings.setValue("j2",4.9);

     settings.setValue("j3",4.7);

     settings.setValue("j4",4.6);

     settings.setValue("j5",4.5);

     settings.setValue("j6",4.4);

     settings.endGroup();

 }

读取ini文件

ReadConfig.cpp

 void GetConfigIni::getConfigMount()

 {

     QVariant strConfigValue;

     QString strConfigGroup = "";

     QString strConfigKey = "";

     QString strfile;

     //strfile = QDir::currentPath();//QCoreApplication::applicationDirPath();

     QString fileName = "config.ini";

     strfile += fileName;

     QSettings user_cfg(strfile,QSettings::IniFormat);

     user_cfg.setIniCodec("UTF-8");

     strConfigGroup = tr("mountinfo");

     user_cfg.beginGroup(strConfigGroup);

     strConfigKey = "mount";

     strConfigValue = user_cfg.value(strConfigKey);

     int Mount = strConfigValue.toInt();

      qDebug()<<"mount*************"<<Mount<<endl;

     user_cfg.endGroup();

     strConfigGroup = tr("v");

     user_cfg.beginGroup(strConfigGroup);

     strConfigKey = "v1";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "v1=*********"<<strConfigValue;

     strConfigKey = "v2";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "v2=*********"<<strConfigValue;

     strConfigKey = "v3";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "v3=*********"<<strConfigValue;

     strConfigKey = "v4";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "v4=*********"<<strConfigValue;

     strConfigKey = "v5";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "v5=*********"<<strConfigValue;

     strConfigKey = "v6";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "v6=*********"<<strConfigValue;

     user_cfg.endGroup();

     strConfigGroup = tr("a");

     user_cfg.beginGroup(strConfigGroup);

     strConfigKey = "a1";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "a1=*********"<<strConfigValue;

     strConfigKey = "a2";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "a2=*********"<<strConfigValue;

     strConfigKey = "a3";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "a3=*********"<<strConfigValue;

     strConfigKey = "a4";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "a4=*********"<<strConfigValue;

     strConfigKey = "a5";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "a5=*********"<<strConfigValue;

     strConfigKey = "a6";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "a6=*********"<<strConfigValue;

     user_cfg.endGroup();

     strConfigGroup = tr("p");

     user_cfg.beginGroup(strConfigGroup);

     strConfigKey = "p1";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "p1=*********"<<strConfigValue;

     strConfigKey = "p2";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "p2=*********"<<strConfigValue;

     strConfigKey = "p3";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "p3=*********"<<strConfigValue;

     strConfigKey = "p4";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "p4=*********"<<strConfigValue;

     strConfigKey = "p5";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "p5=*********"<<strConfigValue;

     strConfigKey = "p6";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "p6=*********"<<strConfigValue;

     user_cfg.endGroup();

     strConfigGroup = tr("j");

     user_cfg.beginGroup(strConfigGroup);

     strConfigKey = "j1";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "j1=*********"<<strConfigValue;

     strConfigKey = "j2";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "j2=*********"<<strConfigValue;

     strConfigKey = "j3";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "j3=*********"<<strConfigValue;

     strConfigKey = "j4";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "j4=*********"<<strConfigValue;

     strConfigKey = "j5";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "j5=*********"<<strConfigValue;

     strConfigKey = "j6";

     strConfigValue = user_cfg.value(strConfigKey);

     qDebug() << "j6=*********"<<strConfigValue;

     user_cfg.endGroup();

 }
