How to create a ChoiceDialog in JavaFX?

A ChoiceDialog is a dialog box that shows a list of choices from which you can select one. You can create a choice dialog by instantiating the javafx.scene.control.ChoiceDialog class.

Example

The following Example demonstrates the creation of a ChoiceDialog.

import javafx.application.Application;
import javafx.collections.ObservableList;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.ChoiceDialog;
import javafx.scene.layout.HBox;
import javafx.scene.text.Font;
import javafx.scene.text.FontPosture;
import javafx.scene.text.FontWeight;
import javafx.scene.text.Text;
import javafx.stage.Stage;
public class ChoiceDialogExample extends Application {
   public void start(Stage stage) {
      //Creating a choice box
      ChoiceDialog<String> choiceDialog = new ChoiceDialog<String>("English");
      //Retrieving the observable list
      ObservableList<String> list = choiceDialog.getItems();
      //Adding items to the list
      list.add("English");
      list.add("Hindi");
      list.add("Telugu");
      list.add("Tamil");
      //Setting the display text
      Text txt = new Text("Click the button to show the choice dialog");
      Font font = Font.font("verdana", FontWeight.BOLD, FontPosture.REGULAR, 12);
      txt.setFont(font);
      //Creating a button
      Button button = new Button("Show Dialog");
      //Showing the choice dialog on clicking the button
      button.setOnAction(e -> {
         choiceDialog.showAndWait();
      });
      //Adding the choice box to the group
      HBox layout = new HBox(25);
      layout.getChildren().addAll(txt, button);
      layout.setPadding(new Insets(15, 50, 50, 50));
      layout.setStyle("-fx-background-color: BEIGE");
      //Setting the stage
      Scene scene = new Scene(layout, 595, 300);
      stage.setTitle("Choice Dialog");
      stage.setScene(scene);
      stage.show();
   }
   public static void main(String args[]){
      launch(args);
   }
}
