Strings in QML can be marked for translation using the qsTr(), qsTranslate(), QT_TR_NOOP(), and QT_TRANSLATE_NOOP() functions.
For example:
Text { text: qsTr("Pictures") }
These functions are standard QtScript functions; for more details see QScriptEngine::installTranslatorFunctions().
QML relies on the core internationalization capabilities provided by Qt. These capabilities are described more fully in:
You can test a translation with the QML Viewer using the -translation option.
First we create a simple QML file with text to be translated. The string that needs to be translated is enclosed in a call to qsTr().
hello.qml:
import QtQuick 1.0 Rectangle { width: 200; height: 200 Text { text: qsTr("Hello"); anchors.centerIn: parent } }
Next we create a translation source file using lupdate:
lupdate hello.qml -ts hello.ts
Then we open hello.ts in Linguist, provide a translation and create the release file hello.qm.
Finally, we can test the translation:
qmlviewer -translation hello.qm hello.qml
You can see a complete example and source code in the QML Internationalization example.
