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

 1 void WriteIni::writeSettings()
 2 {
 3     QSettings settings("config.ini", QSettings::IniFormat); // 当前目录的INI文件
 4 
 5     settings.beginGroup("mountinfo");
 6     settings.setValue("mount",6);
 7     settings.endGroup();
 8 
 9     settings.beginGroup("v");
10     settings.setValue("v1",14.2);
11     settings.setValue("v2",14.3);
12     settings.setValue("v3",14.4);
13     settings.setValue("v4",14.5);
14     settings.setValue("v5",14.6);
15     settings.setValue("v6",14.8);
16     settings.endGroup();
17 
18     settings.beginGroup("a");
19     settings.setValue("a1",2.0);
20     settings.setValue("a2",2.1);
21     settings.setValue("a3",2.2);
22     settings.setValue("a4",2.3);
23     settings.setValue("a5",2.4);
24     settings.setValue("a6",2.5);
25     settings.endGroup();
26 
27     settings.beginGroup("p");
28     settings.setValue("p1",126);
29     settings.setValue("p2",138);
30     settings.setValue("p3",139);
31     settings.setValue("p4",140);
32     settings.setValue("p5",141);
33     settings.setValue("p6",142);
34     settings.endGroup();
35 
36     settings.beginGroup("j");
37     settings.setValue("j1",4.8);
38     settings.setValue("j2",4.9);
39     settings.setValue("j3",4.7);
40     settings.setValue("j4",4.6);
41     settings.setValue("j5",4.5);
42     settings.setValue("j6",4.4);
43     settings.endGroup();
44 }

读取ini文件

ReadConfig.cpp

  1 void GetConfigIni::getConfigMount()
  2 {
  3     QVariant strConfigValue;
  4     QString strConfigGroup = "";
  5     QString strConfigKey = "";
  6 
  7     QString strfile;
  8 
  9     //strfile = QDir::currentPath();//QCoreApplication::applicationDirPath();
 10 
 11 
 12     QString fileName = "config.ini";
 13 
 14     strfile += fileName;
 15     QSettings user_cfg(strfile,QSettings::IniFormat);
 16     user_cfg.setIniCodec("UTF-8");
 17     strConfigGroup = tr("mountinfo");
 18     user_cfg.beginGroup(strConfigGroup);
 19 
 20     strConfigKey = "mount";
 21     strConfigValue = user_cfg.value(strConfigKey);
 22 
 23     int Mount = strConfigValue.toInt();
 24 
 25      qDebug()<<"mount*************"<<Mount<<endl;
 26 
 27     user_cfg.endGroup();
 28
