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

 

 

void tcp_client::WriteSettings()
{
    QSettings settings("Option.ini", QSettings::IniFormat); // 当前目录的INI文件
    settings.beginGroup("DevOption");
    settings.setValue("mainFun", 25);
    settings.setValue("subFun", 40);
    settings.setValue("service", 1);
    settings.endGroup();
}

void tcp_client::ReadSettings()
{
    QSettings settings("Option.ini", QSettings::IniFormat);

    int mainFun = settings.value("DevOption/mainFun").toInt();
    int subFun = settings.value("DevOption/subFun").toInt();
    QString service = settings.value("DevOption/service").toString();

    qDebug() << "service" << service;
    qDebug() << "mainFun" << mainFun;
    qDebug() << "subFun" << subFun;
}


void tcp_client::on_pushButton_read_clicked()
{
    ReadSettings();
}

void tcp_client::on_pushButton_write_clicked()
{
    WriteSettings();
}
