QSetting的使用

QSetting用于保存程序配置和初始化参数。在windows操作系统下用于保存ini配置文件和注册表

ini文件的格式：

 

 

保存配置到注册表

QSettings settings("MySoft","setting");
//保存到network节，键为ip，值为192.168.0.100
//settings.setValue("network/ip","192.168.0.100");
//保存到network节，键为gateway，值为192.168.0.1
//settings.setValue("network/gateway","192.168.0.1");

//设置节的默认值
//settings.beginGroup("network");
//settings.setValue("ip","192.168.0.100");
//settings.setValue("gateway","192.168.0.1");
//settings.endGroup();
//及时同步修改

settings.beginWriteArray("network");
for(int i=0;i<2;++i){
      settings.setArrayIndex(i);
      settings.setValue("ip","192.168.0.100");
      settings.setValue("gateway","192.168.0.1");        
}
settings.endArray();
settings.sync();

qDebug()<<settings.value("network/ip").toString()<<settings.value("network/gateway").toString();

 

保存配置到ini文件

QSetting settings("test.ini",QSettings::IniFormat);
settings.setValue("network/ip","192.168.0.1");
settings.sync();
