Qt Quick I18N▲
When you run the example application, the QML runtime automatically loads a translation from the i18n subdirectory of the directory that contains the main .qml file, based on the system language.
Marking Text as Translatable▲
In the qml-i18n.qml file, use the qsTr command to mark UI text as translatable:
Text {
text: qsTr("Hello")Enabling Translation▲
In the main.cpp file, use QQmlApplicationEngine to automatically load translation files from a subdirectory called i18n in the directory that contains the main QML file:
#include <QQmlApplicationEngine>
int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);
QQmlApplicationEngine engine;The translation file names in the i18n subdirectory must have the prefix qml_. For example, qml_en_AU.ts.
Creating Translation Files▲
Add the LinguistTools module as a value of the find_package command in the CMakeLists.txt file:
find_package(Qt6 REQUIRED COMPONENTS Core Gui Quick Qml LinguistTools)Define the translation files to generate in the qt_add_translations command:
qt_add_translations(qmli18n
TS_FILES
i18n/base.ts
i18n/qml_en.ts
i18n/qml_en_AU.ts
i18n/qml_fr.ts
)Build the application to generate TS and QM files.
On Android, make sure to include the QM files as resources.
Adding Translations▲
To create translations for new languages, copy i18n/base.ts to i18n/qml_<lang>.ts. You can use Qt Linguist to translate the strings.
