prepare for pyqt6 support

[zerobikappa]

I don't understand why the package maintainer of Archlinux skipped krita 5.3.0 and jumped to krita 6.0.0. Unfortunately, this plugin currently does not support pyqt6.

There may be 2 ways to add pyqt6 support:
(1) use Qt.py as dependency;

or

(2) try load pyqt6 everytime, and fix the enum & flag Names, like this:
KnowZero/Krita-PythonPluginDeveloperTools@452d9d8

I'd suggest to use the 5.3.0 AppImage for now. The plugin will be migrate to Qt6 in the near future but not right away.

While I believe using QtPy to be the better choice, I'm not familiar with it and if there are any headaches coming with it
But it would allow krita 5 and 6 users to be able to use the same plugin release without needing to provide separate builds

I did a quick and dirty attempt with gpt 5.4 mini at getting this to work with QtPy and it seems to work. There were some issues with connecting to local comfy but those have been fixed (or so I hope).

I didn't make a PR for this since there wasn't much thought or testing behind this change. Only things I tried are launching Krita 6.0.1 & 5.3.1, connecting to local comfy, generating using normal generate "tab", using custom workflow tab with a few settings. No issues observed there (Krita 6.0.1 installed from arch package repo; Krita 5.3.1, official appimage)

Thanks for this. Why Arch moved from the latest stable to beta Krita 6 beats me, but it's now an awkward situation since simply holding the package back is no longer practical due to dependency conflicts. Using the 5.3 AppImage is also awkward especially when keeping the other Krita 6 installation side-by-side (which I prefer to have for use cases not involving the AI diffusion extension). For the time being this is the best solution for me. For what it's worth I mainly use Qwen Edit and Flux Klein Edit workflows and it works just fine. If this isn't accepted into main that's understandable, but this is a great stopgap solution.

Seconding this, many thanks for this!
To provide another data point: This works fine for me so far. I am on Gentoo, which is also dropping Qt5 finally, after upstream Qt5 OSS support has ended 2020-12-08 and no current packages depend on it anymore (see https://bugs.gentoo.org/948836 ). They have also jumped to Krita 6 stable for this reason instead of packaging the 5.3.0 release which still depends on the dead Qt 5.
With Krita 6 stable being out and better Qt6 Wayland support, Qt5 is gone for good from my system (and will soon be fully gone from Gentoo). It's great we don't have to fall back to the Appimage which would bring backthose EoLd libraries.
So thanks for this effort! 👍

Krita 6 is now the default on Fedora, Ubuntu, Arch...

[davidbrum25]

Well, krita 6.0.1 is default now on Arch > Manjaro, there will be support from the plugin or i need to downgrade somehow?, i dont like the appimage path... i would pretty much prefer to keep it all native and integrated.

[Vaasref]

Yeah, the issue is not about maintaining the plugin for two different version anymore rather than maintaining it for the new default that is Krita 6 and sun-setting Krita 5 support.
