Multilanguage

[anurag-l1nt]

I have implemented the multi-language functionality. The process works as follows:

Change from menu

From the menu option View --> Language, the language can be selected. Once the language is chosen, the application will restart in the same way as when clicking on Restart in to switch networks.

Change from welcomeDialog

• In the WelcomeDialog, which opens when launching Sparrow after the first installation (or the first time it is run on some of the test networks), the first step of the wizard will also allow the selection of the language. If the WelcomeDialog is opened later from the Tools menu, the language change will no longer be allowed there, and it must be done from the menu.

Currently, I have translated the WelcomeDialog, the Transactions tab and the Send tab, pending validation of this proposed solution.

The way to add new languages will be to add a new element to the Languages.java enum and include the .properties file for the new language, which will contain the translations. It is important to add the message for the name of the new language (for example, language.fr for French) to both the new file and the existing ones.
