Close and Minimise button is disabled on Linux using Qt5.3.2

Question

I have created an application using Qt 5.3.2. When the application loads the Close and Minimize buttons appear in case of Mac and Windows, But when i run the same code on Linux these buttons are no longer available.

Can anyone point me to why this maybe happening? This is the code i use to create the main screen.

Here View is object of QQuickView:

    View view(QUrl("qrc:/qml/main.qml"));

    view.setMaximumSize(QSize(1280,700));
    view.setMinimumSize(QSize(1280,700));

    // Centering the App to the middle of the screen
    int width = view.frameGeometry().width();
    int height = view.frameGeometry().height();
    QDesktopWidget wid;
    int screenWidth = wid.screen()->width();
    int screenHeight = wid.screen()->height();
    view.setGeometry((screenWidth/2)-(width/2),(screenHeight/2)-(height/2),width,height);


    view.show();

You can set the windows flag for QQuickView as :

view.setFlags(Qt::WindowMinimizeButtonHint | Qt::WindowCloseButtonHint);
