QProcess app on QWidget, no title & menu bar

[yellowlemontree2014]

hi folks,

I am trying launch an external application, through QProcess, and then trying to set this app on a QWidget. It is working partially, but the app's header title is not appearing. What am I doing wrong, In fact the menu bar is also not hidden. Kindly help me how can I get rid of it.

here's below my code snippet.

    QProcess *process_ = new QProcess();
    process_->start(".\\MGL\\MGL.exe  C:\\datasets\\T1.nii");
    Sleep(20000);
    if (process_->waitForStarted(-1))
    {
        //0.00289917 0.28096 -0.180618 = 343
        HWND id2 = FindWindow(0, L"MGL");

        if (!id2)
            return;
        QTimer t2;
        t2.start(2500);
        QWindow* window2 = QWindow::fromWinId((WId)id2);
        QWidget* widget2 = QWidget::createWindowContainer(window2);
        setCentralWidget(widget2);
    }
