Qt读写ini文件的C++类

一、头文件

#ifndef PRJINI_H
#define PRJINI_H

class QPrjIni
{
private://禁止实例化
QPrjIni();

public:
static bool write(QString section, QString key, QString value, QString path);
static bool read(QString section, QString key, QString &value, QString path);
};


#endif // PRJINI_H\

\

二、源文件

#include "prjini.h"

#include <qsettings.h>


QPrjIni::QPrjIni()
{
}


bool QPrjIni::write(QString section, QString key, QString value, QString path)
{
if (path.isEmpty() || key.isEmpty())
{
return false;
}
else
{
//创建配置文件操作对象
QSettings *config = new QSettings(path, QSettings::IniFormat);


//将信息写入配置文件
config->beginGroup(section);
config->setValue(key, value);
config->endGroup();


//内存释放
delete config;


return true;
}
}


bool QPrjIni::read(QString section, QString key, QString &value, QString path)
{
value = QString("");
if (path.isEmpty() || key.isEmpty())
{
return false;
}
else
{
//创建配置文件操作对象
QSettings *config = new QSettings(path, QSettings::IniFormat);


//读取用户配置信息
value = config->value(section + "/" + key).toString();


//内存释放
delete config;


return true;
}\

}

\

三、应用案例

//软件名称与版本
QString softname;
QString softver;
QString path = qApp->applicationDirPath() + "/config.ini";
QPrjIni::read("setting", "softname", softname, path);
QPrjIni::read("setting", "softver", softver, path);\
