ActiveX and COM in QT

[CertainSci.Owl]

Hello. I need to create a label with animated QMovie gif inside as a COM-object and than add it to another program's window. My code and compile errors are bellow.
I've checked official documentation and different forums but still have no clue what to do.
p.s. maybe my code is nonsense since I'm absolute noob, so I'd appreciate any help

.h file

#ifndef ANIMATION_H
#define ANIMATION_H

#include <QMovie>
#include <QLabel>

class Widget : public QObject
{
    Q_OBJECT

    Q_CLASSINFO("ClassID", "{08690144-E269-4D99-8994-25A7F059CE93}")
    Q_CLASSINFO("InterfaceID", "{086C97D0-4389-4BED-AA16-6AC02F433541}")
    Q_CLASSINFO("RegisterObject", "yes")

    Q_PROPERTY(bool stopped READ isStopped WRITE setStopped)

public:
    explicit Widget(QWidget *parent = 0, QLabel* label = 0);
    ~Widget(){
        delete gif;
    }

    void setStopped(bool);
    bool isStopped();

private:
    QMovie *gif;
    bool stopped;
    bool visible;
};
#endif // ANIMATION_H
