Qt 配置文件读写
在这里用了两个按钮触发配置文件读写操作当pushButton_read按下时读取配置文件内容
pushbutton_write时分别对三个配置文件关键字写入新内容。
settings.setValue("mainFun",25);
settings.setValue("subFun",40);
settings.setValue("service",1);
配置文件格式如下:
[DevOption]
mainFun=50
subFun=40
service=1
1 void tcp_client::WriteSettings() 2 { 3 QSettings settings("Option.ini", QSettings::IniFormat); // 当前目录的INI文件 4 settings.beginGroup("DevOption"); 5 settings.setValue("mainFun", 25); 6 settings.setValue("subFun", 40); 7 settings.setValue("service", 1); 8 settings.endGroup(); 9 } 10 11 void tcp_client::ReadSettings() 12 { 13 QSettings settings("Option.ini", QSettings::IniFormat); 14 15 int mainFun = settings.value("DevOption/mainFun").toInt(); 16 int subFun = settings.value("DevOption/subFun").toInt(); 17 QString service = settings.value("DevOption/service").toString(); 18 19 qDebug() << "service" << service; 20 qDebug() << "mainFun" << mainFun; 21 qDebug() << "subFun" << subFun; 22 } 23 24 25 void tcp_client::on_pushButton_read_clicked() 26 { 27 ReadSettings(); 28 } 29 30 void tcp_client::on_pushButton_write_clicked() 31 { 32 WriteSettings(); 33 }
