Add your own buttons / widgets to the top panel of the Qt window

Question

Is there any easy way to add your buttons / widgets to the top pane of the window as in the example on the screenshot (menu button in old Firefox)?

Or the true path only through:

setWindowFlags(Qt.FramelessWindowHint);

..and drawing your own window frames, the top panel with control buttons and so on?

@AlexanderChernin Thank you, I thought that the simple way without the API of the OS window manager is impossible, you have to draw your own.
Need to draw, see example ru.stackoverflow.com/questions/855760/…
