Change all Text just by Selecting the Language
It's simple to switch the current language in your project. Ignition has several easy ways to change language settings.
Login Screen
One way you can select your preferred language is on the Login screen. There is a dropdown list that automatically appears as soon as you add a second language to your project.

Dropdown Language Selector Component on a Window
You can also switch the language in your project by using the Language Selector Component on your project window. In Preview Mode, select the dropdown language selector component, and choose your desired language.

Using Scripting to Change the Client's Locale
Aside from manually selecting a language, the Client attempts to do this automatically by detecting the locale configured on the host computer. The locale can be specified via scripting with system.util.setLocale. This allows you to utilize scripting events, such as a Client Startup Script to automatically change the client's locale when a user logs in.
