How to hide the menu bar

summit

I want to hide the top menu bar in my QWindow application.

i have a widget which has black color i want it to become fullscreen without the menu bar.

I have given the Frame less window hint but still i get the menu bar.

Qt::WindowFlags flags;

flags = Qt::FramelessWindowHint;

But still the menu bar is visible.

Before you go any further, why are you using a QWindow?

An application will typically use QWidget [...] for its UI, and not QWindow directly.

Separately:

Qt::WindowFlags flags;

flags = Qt::FramelessWindowHint;

This code assigns a local variable. We don't know what you actually do with flags....
