Qt的Q_CLASSINFO简要分析

新建一个继承于QObject的空白类,如下:

class MyInfo : public QObject
{
    Q_OBJECT
public:
    explicit MyInfo(QObject *parent = nullptr);
 
signals:
 
public slots:
};

然后加上Q_CLASSINFO,如下:

class MyInfo : public QObject
{
    Q_OBJECT
    Q_CLASSINFO("Version", "1.0.0")
    Q_CLASSINFO("Author", "xingzaicpp")
public:
    explicit MyInfo(QObject *parent = nullptr);
 
signals:
 
public slots:
};

一对比,一目了然
