Qt 自定义配置文件configfile

1、定义configfile函数为外部静态函数，方便其他直接文件引用。

2、配置文件初始化，先判断路径，没有创建，然后新建配置信息。

3、配置文件读取，写入采取QSetting分组，键值对的方式。

configfile.h

#ifndef CONFIGFILE_H
#define CONFIGFILE_H

#include "globe_data.h"
#include "system_config.h"
class ConfigFile
{
public:
    ConfigFile();
    ~ConfigFile();
    //----------配置文件----------//
    static int  ConfigFile_Init();
    static void ConfigFile_Read_SetUp(Globe_Data *g);//返回读取的个数
    static void ConfigFile_Write(Globe_Data *g);
};

#endif // CONFIGFILE_H

configfile.cpp

#include "configfile.h"

#include <QDir>
#include <QSettings>
#include <QDebug>
