True Headless Mode

[WojOstr]

Is it possible to implement a window without a header? I noticed that there is a "Headless Mode" on the dev branch, after rewriting it to python and examining the example I noticed that it creates a virtual window, which is not my expected effect. This would really help me and my program, as I'm using multiple windows. Thanks.

I am not very sure about this. I think the headless mode implemented in the dev branch is an initial step to provide a fully headless experience. As displayed in your screenshot, this window is very likely a consequence of some OpenCV window/loop function being called to process everything.

It would be a matter of identifying which function is that and preventing it of being called. That will cause other problems, like the event loop of OpenCV not handling things properly (so the program might become unresponsive). As I said, it is something to be investigated.

Thanks for your answer
I think you might missunderstand my problem/issue, as i missunderstanted what really "headless" is.

What I would like to achieve in my program, is somehow "hiding" the header of window, or at least deny option to maximize the window to fullscreen, is it possible?

I.E, in this case there would be no header with "WINDOW_SE..." " "

Oh, now I got it 😄 Thanks for explaining it further!

Unfortunately we cannot achieve that using OpenCV alone, since it has no API to hide the header of the window. Maybe that would be possible using Qt, but cvui itself will not be able to help.
