The name parameter of KisCurveOption is being used as the item value, by default it is not being translated. Other examples include SmudgeRadius, SmudgeRate and PaintThickness.

Is it possible to give these parameters their strings? I don't know the whereabouts of those parameters, can you point me to their files? Is it possible to just turn them into something like:

i18n("STRING")
i18nc("COMMENT", "STRING")

(Sorry I'm not familiar with programming and have only a vague understanding of i18n).

It looks like you want plugins/paintops/libpaintop/kis_pressure_lightness_strength_option.cpp , line 9

Thanks! I'll fix them today!

I tried to fix them, I hope it works.

MR:
https://invent.kde.org/graphics/krita/-/merge_requests/1034
https://invent.kde.org/graphics/krita/-/merge_requests/1035

So according to Dmitry:
https://invent.kde.org/graphics/krita/-/merge_requests/1035#note_299642

"This string must not be translated, it is used when saving real settings into XML. The actual translated name comes in KisBrushOpSettingsWidget"

Changes reverted.

So the string has been translated in "kis_brushop_settings_widget.cpp" but it was somehow unused in Brush HUD configuration dialogue. Instead the program's real parameter was used. I suppose this should be fixed by whom wrote the dialogue? I have no idea of how things work at this level.

Unassigning myself from assignee.

I've debugged and fixed this locally; however, because of the way some of the paintop options are constructed, I will have to be very careful of the changes involved.

For instance, the option for "smudge_length" uses actually two IDs. One of them is the ID provided to the KisCurveOptionUniformProperty (so far so good). The other, which is supposed to be its internationalizable name (like the callback-based ops) is not localized because it is also (incorrectly, semantics wise) used as the option's own ID to retrieve its settings.

A possibly relevant merge request was started @ https://invent.kde.org/graphics/krita/-/merge_requests/1197
