QT写配置参数到程序注册表和ini文件

admin

1. #include "mainwindow.h"
   
2. #include <QSettings>
   
3. #include <QApplication>
   
4. int main(int argc, char *argv[])
   
5. {
   
6.     QApplication a(argc, argv);
   
7.     //配置参数，在注册表中会创建相关的项
   
8.     QCoreApplication::setOrganizationName("QQQQQ");
   
9.     QCoreApplication::setOrganizationDomain("qqqqq.com");
   
10.     QCoreApplication::setApplicationName("WWWWW");
    
11.     QCoreApplication::setApplicationVersion("1.0.0");
    
12.     //写设置值，注册表中会写入相关的值
    
13.     QSettings setting;
    
14.     setting.setValue("ip","127.0.0.1");
    
15.     setting.setValue("port","3306");
    
16.     setting.setValue("name","cch");
    
17.     setting.setValue("password","cch");
    
18. 
    
19.     MainWindow w;
    
20.     w.show();
    
21.     return a.exec();
    
22. }

1. 把参数写入到ini文件

复制代码

#include "mainwindow.h"
#include <QSettings>
#include <QApplication>
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    //配置参数
//    QCoreApplication::setOrganizationName("QQQQQ");
//    QCoreApplication::setOrganizationDomain("qqqqq.com");
//    QCoreApplication::setApplicationName("WWWWW");
//    QCoreApplication::setApplicationVersion("1.0.0");
    //写设置值
    QSettings *setting = new QSettings("QWSet.ini", QSettings::IniFormat);
    setting->setValue("/MySql/ip","127.0.0.1");
    setting->setValue("/MySql/port","3306");
    setting->setValue("/MySql/name","cch");
    setting->setValue("/MySql/password","cch");
    delete setting;

    MainWindow w;
    w.show();
    return a.exec();
}
从注册表中读取写入的值
QSettings setting;
QString ip = setting.value("ip").toString();
QString port = setting.value("port").toString();
QString name = setting.value("name").toString();
QString password = setting.value("password").toString();
