Основними кроками (серед інших) інтернаціоналізації програм Java є пошук Locale
і збір ресурсів. У JavaFX ви можете використовувати FXMLLoader#setResources()
для цих цілей. Тут демонструється демонстрація SSCCE. Коди є самоописовими.
Структура демонстраційного пакету:
bundledemo
|------ BundleDemo.java
|------ MyController.java
|------ MyView.fxml
bundles
|------ MyBundle_en.properties
|------ MyBundle_kg.properties
MyBundle_en.properties
key1=Name Surname
key2=How are you?
MyBundle_kg.properties
key1=Aты Жөнү
key2=Кандайсың?
MyView.fxml
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.*?>
<BorderPane fx:controller="bundledemo.MyController" xmlns:fx="http://javafx.com/fxml">

<!-- This label's text will be set by the controller -->
<Label fx:id="lblTextByController"/>

<!-- This label's text will be taken from the bundle automatically -->
