* Add multi-language i18n support (English, Chinese, Japanese, Korean)
- Add i18n.py module for translation management via QTranslator
- Add Simplified Chinese (zh_CN), Japanese (ja_JP), and Korean (ko_KR) translations
- Integrate translation files into Qt resource system (KCC.qrc / KCC_rc.py)
- Add language switcher button in the top button bar of main window
- Language setting persists via QSettings
- Dynamic text updates work correctly after language switch
- Support %1, %2, %3 placeholders via tr_arg() helper function
- KCCGUI and KCCGUI_MetaEditor now inherit QObject for tr() support
* Complete Japanese/Korean/Chinese translations + fix language switch issues
- Fill 61 missing Japanese translations (tooltips, 3-state checkboxes, etc.)
- Fill 61 missing Korean translations (tooltips, 3-state checkboxes, etc.)
- Fill 6 missing Chinese translations
- Fix language menu: use QActionGroup for exclusive (single-select) checkmarks
- Fix jobList initial tips: refresh translations on language switch by
updating label text directly (preserves message order and user-added entries)
- Add PROJECT_I18N_README.md developer documentation
* Replace emoji language icon with PNG globe icon
Fixes PR review feedback from axu2: the emoji character doesn't render on Windows 7 (no emoji font support). Replaced with a PNG globe icon from Wikimedia Commons (CC license), loaded via Qt resource system for consistent cross-platform rendering.
* Fix RuntimeError when switching language: re-fetch labels from jobList
Previously, QLabel references were saved directly, but the underlying
C++ objects could be deleted by Qt, causing RuntimeError on access.
Now we save only source strings and re-fetch labels from jobList
items when updating, with try/except as a safety net.
* Use text label for language button instead of PNG icon
Replace the globe PNG icon with a plain text button (' 文 A ')
so its color automatically follows the system light/dark theme,
per review feedback. Removes icons/language.png and its QRC entry.
* Finalize i18n: retranslate jobList messages and translate CLI output
- Add source= to 16 GUI addMessage calls so already-shown messages retranslate on language switch
- Translate comic2ebook.py conversion/CLI messages via QCoreApplication.translate('KCCGUI', ...)
- Clear 29 unfinished WorkerThread translations (context unified to KCCGUI)
- Guard apply_language when QApplication is not yet created
- Trim dead imports and redundant code
* Avoid duplicated source strings: translate inside addMessage
Replace the self.tr/translate + source= pattern (same string written twice) with
QT_TRANSLATE_NOOP('KCCGUI', ...) at call sites; addMessage now translates internally
and stores the source text for retranslation on language switch.
- Drop the source parameter from addMessage; simplify signal to 3 args
- Include comic2ebook.py in lupdate (20 CLI/conversion messages)
* Add translation maintenance workflow
Add gen_translation_files.sh/.bat, TRANSLATION.md, and a README pointer; remove the superseded PROJECT_I18N_README.md.
