\title Adding Multi-language Support to Your Project
\brief Illustrates how to add support for multiple languages to your
project.
\image multilanguage-project.png
The \e{Multi-language Support} tutorial illustrates how you can add
support for multiple languages to your project. In this tutorial you
prepare a simple log in UI for multi-language support and import
translations from a JSON file.
You need to download the starting project for this tutorial from
\l{https://git.qt.io/public-demos/qtdesign-studio/-/tree/master/tutorial%20projects/multi-language%20tutorial/Loginui2}{here}
before you start.
Download the project and open the \e loginui2.qmlproject file in \QDS
to get started.
This project consists of a login page with a couple of text elements.
Additionally, you will use a JSON translation file in this tutorial.
Download it from \l{https://git.qt.io/public-demos/qtdesign-studio/-/tree/master/tutorial%20projects/multi-language}{here}.
\section1 JSON Translation File
The JSON translation file you are using in this project has the following
structure:
\code
{
"translatables": [
{
"trId": "translation_password",
"translations": [
{
"language": "en",
"translation": "Password"
},
{
"language": "sv",
"translation": "Lösenord"
}
]
},
{
"trId": "translation_account",
"translations": [
{
"language": "en",
"translation": "Qt Account"
},
{
"language": "sv",
"translation": "Qt Konto"
}
]
},
{
"trId": "translation_createaccount",
"translations": [
{
"language": "en",
"translation": "Create Account"
},
{
"language": "sv",
"translation": "Skapa Konto"
}
]
},
{
"trId": "translation_login",
"translations": [
{
"language": "en",
"translation": "Log In"
},
{
"language": "sv",
"translation": "Logga In"
}
]
},
{
"trId": "translation_username",
"translations": [
{
"language": "en",
"translation": "Username"
},
{
"language": "sv",
"translation": "Användarnamn"
}
]
}
]
}
\endcode
\section1 Preparing Your Project
First, you need to prepare your project for translation:
\list 1
\li In \uicontrol{Projects}, double-click \e{Screen01.ui.qml} to open it.
\li All text strings that you want to translate need to be of \c
qsTrId type. In this project the text strings are of \c qsTr type so you
need to change them. Open \uicontrol{Text Editor}, find all five
occurrences of \c qsTr and replace them with \c{qsTrId}. For example,
replace:
\code
text: qsTr("Qt Account")
\endcode
with:
\code
text: qsTrId("Qt Account")
\endcode
\li Next, you need to replace the text value with the text string
variable from the translation file for the five text strings you want
to translate. For example, replace:
\code
text: qsTrId("Qt Account")
\endcode
with:
\code
text: qsTrId("translation_account")
\endcode
\endlist
\section1 Importing Translations
Next, you need to import your JSON translation file:
\list 1
\li Go to \uicontrol View > \uicontrol Views and select \uicontrol
Translations to open the \uicontrol Translations view. You can
drag it to a workspace to dock it.
\li In \uicontrol Translations, select
\inlineimage icons/select-languages.png
.
\li Select the languages that you want to support in your project,
in this case \uicontrol{English - American English} and
\uicontrol{Swedish - Svenska}.
\li Set \uicontrol{English - American English} as primary language and
select \uicontrol{Ok}.
\li Select \inlineimage icons/import-json-translations.png
and open the \e ml_translations.json file. Now you can see all your
imported translations in the \uicontrol Translations view.
\image imported-translations.png
\endlist
You can select language from the dropdown list on the left side of the
\uicontrol Translations view. Translations for the selected languages will
show in the \uicontrol Translations view as well as in
\uicontrol{Form Editor}.
You can run translation tests, import, and export translations as described
in \l{Translations}.
Finally, before you can see your translations in the application or in
\uicontrol{Live Preview}, you must generate Qt translation source files.
To do this, select
\inlineimage icons/generate-translation-files.png
in the \uicontrol Translations view.
