Fix automatic QML type registration for Qt 6.3.x

[Holzhaus]

Works around QTBUG-104373.

[Holzhaus]

Yikes, now we have a mismatch between CI qmlformat and local qmlformat because it's a system depedency that does not allow pinning :(

[Holzhaus]

I removed the formatting changes for now, I'll take care of that in a separate PR.

EDIT: See #10929.

Fix confirmed! It actually works with library and playback and all!

[Holzhaus]

Shall we merge then?

[m0dB]

Sounds good to me. But I wonder how you have been able to commit: When I try to commit qml files (e.g. main.qml without any actual changes) qmllint fails:

Warning: res/qml/main.qml:2:1: Warnings occurred while importing module "Mixxx":
import Mixxx 1.0 as Mixxx
^^^^^^
---
Warning: Failed to import Mixxx. Are your include paths set up properly?
---

Warning: res/qml/main.qml:73:25: Unqualified access
                        Mixxx.PreferencesDialog.show();
                        ^^^^^

Doesn't this happen to you?

I see I can run qmllint successfully with these arguments:

qmllint -I build/qml/Mixxx/ -i build/qml/Mixxx/qmldir res/qml/main.qml

Any suggestions how to deal with this? BTW, I notice that 6.3.2 qmlformat does some weird stuff, like this:

-            Skin.FadeBehavior on visible {
+            Skin.FadeBehavior on visible  {

We have a policy of not merging our own PRs, so this was just a small hint to the other core team members to have a look 😉

qmllint does not complain on my machine. If it doesn't work for you, you probably have a different qmllint version installed.

$ pre-commit run qmllint --all-files
qmllint..................................................................Passed
$ qmllint --version
qmllint 1.0

Let's discuss this on #10929.

Code LGTM. Waiting for my local build so I can confirm with a smoke test. Thanks.

[Swiftb0y]

fyi I unwatched the repo. So please @ me or request a review if you need my involvement.

works with Qt 6.3.1 ✔️

[Holzhaus]

Thanks!
