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
