[Interest] What is the state of Wayland support in Qt 6.10

[Marius Kittler]

I haven't followed discussions for a while. However, I think the following is 
still how it is: Allowing applications to do this kind of "low-level" window 
management is not wanted by the community developing Wayland (the protocol and 
the desktop environments). So unless the Wayland community changes their mind 
you cannot port your application to Wayland without redesigning these aspects.

In case you haven't come across this infamous Gist (which is probably not up-
to-date anymore):

Maybe something was merged on
https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests
that could help and just needed to be implemented in the Qt Wayland platform 
plugin. I somehow doubt it, though.

After a brief check I only found
https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/247
and
https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/249
again which are both closed.

There's also https://github.com/KDE/layer-shell-qt/tree/master but last time I 
checked it had the disadvantage that then your entire application had to use 
that shell.

You may also resort to compositor-specific hacks like
https://github.com/KDE/yakuake/blob/master/app/mainwindow.cpp#L157. (This is a 
KDE application. For a desktop-neutral application something like that doesn't 
make much sense so. Btw, when I asked KDE devs about this kind of 
functionality for Syncthing Tray I was also told that this is not wanted. Now 
I find hacks like that in a KDE app.)
