    well my "theory" is that
    if QAxWidget is assigned to a parent before FramelessWindowHint
    then bug comes.

      @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);
                ..
                }

                      @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 ...

                        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?
