Change the UI language
Qt Creator has been localized into several languages. If the system language is one of the supported languages, it is automatically selected.
To change the language:
- Go to Preferences > Environment.
- In Language, select a language.
- Select OK.
- Select Restart Now to restart Qt Creator and have the change take effect.
Set the language from the command line
To set the UI language when you start Qt Creator from the command line, enter:
qtcreator -language <locale>
Use a lowercase, two-letter ISO 639 language code, such as de, en, or fr.
