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);
