Translations

iCUE widgets support localization through JSON translation files and the tr() helper.

Translation File

File Location

Place the translation file in the same directory as index.html.

MyWidget/
├── index.html
├── translation.json
└── resources/
    └── icon.svg

File Format

Using Translations

In Meta Parameters

Use tr('key') in data-label, title, and other attributes:

<title>tr('My Widget')</title>

<meta
    name="x-icue-property"
    content="textColor"
    data-label="tr('Text Color')"
    data-type="color"
    data-default="'#ffffff'"
/>

<script type="application/json" id="x-icue-groups">
    [
        {
            "title": "tr('Appearance')",
            "properties": ["textColor", "backgroundColor"]
        }
    ]
</script>

In JavaScript

The tr() function returns a Promise:

async function updateUI() {
    const label = await tr("Hello");
    document.getElementById("greeting").textContent = label;
}

tr("Settings").then((text) => {
    document.getElementById("title").textContent = text;
});

Multiple translations:

async function initTranslations() {
    const [hello, settings, save] = await Promise.all([
        tr("Hello"),
        tr("Settings"),
        tr("Save"),
    ]);
    document.getElementById("greeting").textContent = hello;
    document.getElementById("title").textContent = settings;
    document.getElementById("saveBtn").textContent = save;
}
