Choice Box

Question

How do I make to populate choice box in the JavaFX Scene Builder? I have that to make a class or is there another way?
Thanks!

Hi,
1. In SceneBuilder, add a unique fx:id to your ChoiceBox object - this fx:id should be the name of a private variable in your controller's class.
<AnchorPane id="AnchorPane" ... xmlns:fx="http://javafx.com/fxml" fx:controller="myexample.MyController">
<children>
<ChoiceBox fx:id="myChoiceBox" layoutX="257.0" layoutY="190.0"/>
</children>
</AnchorPane>
2. In your controller's initialize method, initialize the content of your choice box.
package myexample;
import ...
public class MyController implements Initializable {
@FXML // fx:id="myChoices"
private ChoiceBox<?> myChoices; // Value injected by FXMLLoader
@Override // This method is called by the FXMLLoader when initialization is complete
public void initialize(URL fxmlFileLocation, ResourceBundle resources) {
assert myChoices != null : "fx:id=\"myChoices\" was not injected: check your FXML file 'foo.fxml'.";
// initialize your logic here: all @FXML variables will have been injected
// => you can add items to "myChoices" here:
myChoices.setItems(FXCollections.observableArrayList());
myChoices.getItems().add(...);
}
