Qt6

[jschueller]

Requires #11569, not finished

• many changes are related to QRegExp which is deprecated in favor of QRegularExpression that is already available in qt5
  the problem is that the variables widgets relies on the different pattern syntaxes QRegExp offers but are not available in QRegularExpression, it would be simpler to only support perl expression (and wildcards maybe) so that everything could be moved to QRegularExpression and not duplicate some code

• many changes are related to qwt which must be bumped to 6.2

maybe I should split some of these changes in several PRs, what do you think ?

I agree. The default right now is perl pattern matching syntax and I don't think people are actually using other pattern syntaxes.

Yes please. Its too many files to review at one go. Split into several PRs and I will start reviewing them. Thanks!

LGTM. Thanks!

Are we not required to register our own types?

[jschueller]

seems that was only required for qt5

I will merge this one after we are done with 1.23 release. I should have reviewed it earlier but sorry I couldn't manage the time.

Regarding PatternSyntax, I believe you will make a separate PR once this is merged.

The compiled OMEdit crashes on startup with,

Thread 1 "OMEdit" received signal SIGABRT, Aborted.
__pthread_kill_implementation (no_tid=0, signo=6, threadid=140736846681536) at ./nptl/pthread_kill.c:44
44      ./nptl/pthread_kill.c: No such file or directory.

OMShell output only prints first character,

OMNotebook is completely off,

OMEdit crashes in webengine libs on ubuntu 22 (qt 6.2), but ok on arch (qt 6.7)
which qt version did you test ?

I don't know how else I can test this. There is Arch WSL at the Microsoft store. I will try that.
