How to create a ComboBox using JavaFX?

JavaFXObject Oriented ProgrammingProgramming

A combo box is similar to a choice box it holds multiple items and, allows you to select one of them. It can be formed by adding scrolling to a drop-down list. You can create a combo box by instantiating the javafx.scene.control.ComboBox class.

Example

The following Example demonstrates the creation of a ComboBox.

import javafx.application.Application;
import javafx.collections.ObservableList;
import javafx.geometry.Insets;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.ComboBox;
import javafx.scene.control.Label;
import javafx.stage.Stage;
import javafx.scene.layout.HBox;
import javafx.scene.paint.Color;
import javafx.scene.text.Font;
import javafx.scene.text.FontPosture;
import javafx.scene.text.FontWeight;
public class ComboBoxExample extends Application {
   public void start(Stage stage) {
      //Setting the label
      Label label = new Label("Select Desired Course:");
      Font font = Font.font("verdana", FontWeight.BOLD, FontPosture.REGULAR, 12);
      label.setFont(font);
      //Creating a combo box
      ComboBox<String> combo = new ComboBox<String>();
      //Setting the prompt text of the combo box
      combo.setPromptText("Select Course");
      //Getting the observable list of the combo box
      ObservableList<String> list = combo.getItems();
      //Adding items to the combo box
      list.add("Java");
      list.add("C++");
      list.add("Python");
      list.add("Big Data");
      list.add("Machine Learning");
      HBox hbox = new HBox(15);
      //Setting the space between the nodes of a HBox pane
      hbox.setPadding(new Insets(75, 150, 50, 60));
      hbox.getChildren().addAll(label, combo);
      //Creating a scene object
      Scene scene = new Scene(new Group(hbox), 595, 280, Color.BEIGE);
      stage.setTitle("Combo Box");
      stage.setScene(scene);
      stage.show();
   }
   public static void main(String args[]){
      launch(args);
   }
}
