How to put QWidget objects on top of a QWindow?

? Offline

Hello there,
I want to put an QWidget object with some QPusbutton objects as a control panel on top of an QWindow object with OpenGL context rendered. However, I found that the QWidget objects can't display. It seems that they are always "covered" beneath the OpenGL context. Is there any work around where I can put QWidget objects above the QWindow?

I have tried QWidget::createWindowContainer() but no luck.

@JoeCFD I can only use QWindow, so the soluton inside the link doesn't apply. Thanks.
