Q_PROPERTY 自定义属性不生效

发现一个问题，当自定义属性的类，不加Q_OBJECT，那么此类的自定义属性，不能被外界更改使用

class COnlyPushNormalBtn : public QPushButton
{
   
   
    Q_OBJECT //发现必须要加这个宏
    Q_PROPERTY(bool isJogMode READ getIsJogMode WRITE setIsJogMode DESIGNABLE true)
    Q_PROPERTY(bool fixMoveChecked READ getFixMoveChecked WRITE setFixMoveChecked DESIGNABLE true)
public:
    COnlyPushNormalBtn(QWidget *parent = nullptr);
    bool getIsJogMode() const;
    void setIsJogMode(bool value);
    bool getFixMoveChecked() const;
    void setFixMoveChecked(bool value);
protected:
    virtual void mousePressEvent(QMouseEvent *event) override;
    virtual void mouseReleaseEvent(QMouseEvent *event) override;
private:
    bool isJogMode;//是否是点动按钮模式：鼠标点击按下，松开弹起
    bool fixMoveChecked;//定长运动时，是否按下
};

#include "conlypushnormalbtn.h"
