The QML runtime automatically loads a translation from the i18n subdirectory of the root QML file, based on the system language.
The files are created or updated by running:
lupdate qml-i18n.qml -ts i18n/base.ts
Translations for new languages are created by copying i18n/base.ts to i18n/qml_<lang>.ts The .ts files can then be edited with Qt Linguist :
linguist i18n/qml_fr.ts
The run-time translation files are then generated by running:
lrelease i18n/*.ts
注意： On Android, please make sure to include the generated *.qm files as resources.
