Introduction

In this chapter, we will internationalize our GUI by displaying text on labels, buttons, tabs, and other widgets, in different languages.

We will start simply and then explore how we can prepare our GUI for internationalization at the design level.

We will also localize the GUI, which is slightly different from internationalization.

Note

As these words are long, they have been abbreviated to use the first character of the word, followed by the total number of characters in between the first and last character, followed by the last character of the word.

So, internationalization becomes I18N and localization becomes L10N.

We will also test our GUI code and write unit tests and explore the value unit tests can provide in our development efforts which will lead us to the best practice of refactoring our code.
