Internationalization Example


The QML runtime automatically loads a translation from the i18n subdirectory of the root QML file, based on the system language. The translations are held in QM files that must be generated from TS files.

Updating Translations

The .ts files are created and updated by running:

lupdate i18n.qml -ts i18n/base.ts

If no translation file exists, one will be created. If a file already exists, it will be updated to contain the latest strings from the QML file.

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
