Change UI language for Qt Creator IDE
As a default behavior Qt Creator uses the language according to the system’s regional settings. Often this is not what developers are expecting. Even developers from Europe (e.g. Austria, Germany) are used to have their IDE in English.
In order to “force” the Qt Creator displaying its UI in English you can add an environment variable:
- LANG=en_US
Note that the value of the LANG environment variable is not en-US which may some of you would expect. After restarting the Qt Creator you’ll see all menus, dialogs etc. in US English.
