QT中enum和QString的互相转换。

#include <QObject>
class Cenum: public QObject
{
    Q_OBJECT
public:
    Cenum() {}
    
    enum Priority
    { 
        High, 
        Low,
        VeryHigh, 
        VeryLow 
    };
    Q_ENUM(Priority)
};

1      qDebug()<<Cenum::High<<"\t"<<Cenum::Low;                     //！qDebug可以直接打印出枚举类值的字符串名称
2      QMetaEnum metaEnum = QMetaEnum::fromType<Cenum::Priority>();
3      qDebug()<<  metaEnum.valueToKey(Cenum::VeryHigh);            //! enum转string
4      qDebug()<<  metaEnum.keysToValue("VeryHigh");                //！string转enum
