wallpaper plugin with translations

SUMMARY

I am trying to add localization support to a third-party wallpaper plugin ([smart-video-wallpaper-reborn](https://github.com/luisbocanegra/plasma-smart-video-wallpaper-reborn)), but translations are not loading when they are built into the wallpaper (`contents/translations/`).

STEPS TO REPRODUCE

1. Install attached plasma-smart-video-wallpaper-reborn-v2.0.0.zip
2. Change the system language to es/pt_BR
3. Reboot then open the wallpaper plugin settings

OBSERVED RESULT

Wallpaper and its settings are still in english

EXPECTED RESULT

Wallpaper should follow use the provided translations

Graphics Processor: Intel® UHD Graphics 630

ADDITIONAL INFORMATION

If I copy the translation files to `/usr/share/locale` or `~/.local/share/locale/` then they load only [if the translation domain is passed on all translatable strings `i18nd()`](https://github.com/luisbocanegra/plasma-smart-video-wallpaper-reborn/commit/346dbbd48364038b991f95a8db8f28b2f4586b57) and this confuses me even more because widgets for example don't require passing domain.

Comment 1 Méven 2025-03-12 11:23:53 UTC

This is not a bug in any KDE software.

Refer to
https://doc.qt.io/qt-6/i18n-source-translation.html

You can also check how KDE Plasma code does it.

Reopening because I needed to patch libplasma to make it work
