    @mrjj Then the solution is not to create QAxWidget in the constructor?

    Well I assume u tested that ?
    Create it after setupUI and FramelessWindowHint does not make it work ?

    If no, you can try with the showEvent
    void maiwinxx::showEvent( QShowEvent* event ) {
    QMainwindxx::showEvent( event );

    // create it here.

    }

        Hi, np. That was what i wanted to test.

        So if we create it before windows is fully shown we get bug?

        But if you create in button_click , it works?

            very strange!
            I though showEvent would been same as clicked.
            Try timer so that we first create after window fully shown.

            // in constructor
            QTimer *timer = new QTimer(this);
            connect(timer, SIGNAL(timeout()), this, SLOT(nowcreate()));
            timer->start(4000);
            }

            void MainWindow::nowcreate() << add this to .h also
            {
            qDebug() << "nowcreate";
            // create here
            QAxWidget *Test = new QAxWidget(this);
            ..
            }

                so window must be fully shown to make it happy.

                  @mrjj Thank you very much for your help! So show window, and then create a widget ... So still the question, it is a bug Qt or something else? The problem can be considered solved only in the bug tracker you need to add ...

                    You are most welcome.
                    well I think its a bug but not sure.
                    When bug comes, it seems to me it hangs. That seems like bug.

                    Oh I forgot to ask.
                    What is {8856f961-340a-11d0-a96b-00c04fd705a2} ?

                              Have you tried with Qt 5.5 ?
                              Maybe QAxWidget has bug in 5.6

                                Hello!

                                I faced a similar problem, tried hacks with single QTimer and showEvent: timer was a solution, and showEvent -- wasn't. I also use Win10, but Qt5.5.1. Have you succeeded?
