    Ok, but in both cases, its included in the UI from start?
    It seems once active it dont like FramelessWindowHint

    I would look in
    https://bugreports.qt.io/secure/Dashboard.jspa

    and also test if you insert from code only
    not having it in UI .

      I tried so

      MainWindow::MainWindow(QWidget *parent) :
          QMainWindow(parent),
          ui(new Ui::MainWindow)
      {
          ui->setupUi(this);
          this->setWindowFlags(Qt::FramelessWindowHint);
      }
      

      like this

      void MainWindow::on_pushButton_clicked()
      {
          this->setWindowFlags(Qt::FramelessWindowHint);
          this->show();
      }
      

      and

      int main(int argc, char *argv[])
      {
          QApplication a(argc, argv);
          MainWindow w;
          w.setWindowFlags(Qt::FramelessWindowHint);
          w.show();
          qDebug() << w.windowFlags();
      
          return a.exec();
      }

        @Tikitko said:

        setWindowFlags(Qt::FramelessWindowHint);

        ok, but the flag is not the issue. that works.

        I was thinking about
        void MainWindow::on_pushButton_clicked()
        {
        QAxWidget *Test = new QAxWidget(this);
        Test->Show();
        .. other setup

        and not have it in UI.
        just to test.

              QAxWidget *Test = new QAxWidget(this);
              Test->setControl("{8856f961-340a-11d0-a96b-00c04fd705a2}");
              Test->dynamicCall("Navigate(const  QString&)","http://vk.com/");

            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 ...

                                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} ?

                                      Ehh. not sure I read that correctly.

                                      You say that if made with button, then bug dont show, but if you minimize and maxi window again, bug comes back?

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