[Interest] Modeless dialog issue on Mac

[Tor Arne Vestbø]

As a workaround you can try static_cast<NSView*>(window.winId()).window.windowLevel = NSNormalWindowLevel + 1

In a .mm file or build your cpp file with -x objective-c++

Thanks Oliver for you hint,

I tried the example application you suggested, it seems none of the flags combination results in the wanted result: either the window is behind the main application or it is on top of all desktop applications

But I understand your use case better now, and yes, it is different from mine. However I don‘t know any „top of application (only)“ flag myself (not saying that Qt doesn’t provide such a flag - I just don’t know).

And what do we do if we developers are too lazy to read the fine manual? Exactly! We have someone else read it for us - like your favourite LLM! ;)

Here is what ChatGPT has to say about it:

Quote: „ Yes, in Qt, there is a flag that can be used to make a modeless dialog stay on top of the application. This flag is called Qt::WindowStaysOnTopHint. By setting this flag on a modeless dialog, you can ensure that the dialog remains on top of all other windows in the application.“

And even better: a quick research reveals that this flag („hint“) actually seems to exist ;)

In fact, you can try it out right away and tell us how it went:

;)

Hope that helps!
