Qt配置文件读写

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

1void tcp_client::WriteSettings()

2 {读取配置文件失败

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);

15int mainFun = settings.value("DevOption/mainFun").toInt();

16int subFun = settings.value("DevOption/subFun").toInt();

17 QString service = settings.value("DevOption/service").toString();

19 qDebug() << "service" << service;

20 qDebug() << "mainFun" << mainFun;
