[C++知识库]Qt枚举类型获取对应数字和字符串

通过枚举类型获取对应数字和字符串, 将枚举类型封装到类中, 本文以Qt举例, 程序如下.

season.h

#ifndef SEASON_H
#define SEASON_H

#include <QStringList>

class Season
{
public:
    enum SeasonType{
        Spring, Summer, Autumn, Winter
    };

    static QString getItem(SeasonType type);
    static int getValue(SeasonType type);

private:
    static void initial();
    //
    static bool m_initFlag;
    static QStringList m_seasonList;
};

#endif // SEASON_H

season.cpp

#include "season.h"

bool Season::m_initFlag = true;
QStringList Season:: m_seasonList;
QString Season::getItem(Season::SeasonType type)
{
    initial();
    return m_seasonList.at(type);

}

int Season::getValue(Season::SeasonType type)
{
    return (int)type;
}

void Season::initial()
{
    if(m_initFlag){
        m_seasonList.append("spring");
        m_seasonList.append("summer");
        m_seasonList.append("autumn");
        m_seasonList.append("winter");

        m_initFlag = false;
    }
}

main.cpp

#include <QDebug>
#include "season.h"

int main(int argc, char *argv[])
{
    Season::SeasonType type = Season::Summer;
    qInfo()<<"aaaa11"<<Season::getItem(type)<<Season::getValue(type);

    return 0;
}
