10. FXML
class CounterView : View() {
override val root : BorderPane by fxml()
val counter = SimpleIntegerProperty()
val counterLabel: Label by fxid()
init {
}
counterLabel.bind(counter)
}
fun increment() {
}
counter.value += 1
Our app is now complete. Every time the button is clicked, the label will increment its
count.
Internationalization
JavaFX has strong support for multi-language UI's. To support internationalization in FXML,
you normally have to register a resource bundle with the FXMLLoader and it will in return
replace instances of resource names with their locale-specific value. A resource name is the
key in the resource bundle prepended with % .
TornadoFX makes this easier by supporting a convention for resource bundles: Create a
resource bundle with the same base name as your View , and it will be automatically
loaded, both for use programatically within the View and from the FXML file.
Let's internationalize the button text in our UI. Create a file called CounterView.properties
and add the following content:
clickToIncrement=Click to increment
If you want to support multiple languages, create a file with the same base name followed by
an underscore, and then the language code. For instance, to support French create the file
CounterView_fr.properties . The closest geographical match to the current locale will be
used.
clickToIncrement=Cliquez sur incrément
Now we swap the button text with the resource key in the FXML file.
