We’ve prepared these code snippets to help you learn JavaFX.

Example 1: Contextmenu

Here are the code snippets:

Step 1: Create Project

  1. Open your favorite Java IDE.
  2. In the menu go to File --> Create New Project.

Step 2: Dependencies

No dependencies are needed for this project.

Step 3: Write Code

Our code will comprise the following java files:

  • ContextMenuExample.java
  1. In your editor or IDE, create a file known as ContextMenuExample.java.
  2. Then add the following code:

(a). ContextMenuExample.java

We will need to add a bunch of imports in our class:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.ContextMenu;
import javafx.scene.control.MenuItem;
import javafx.scene.control.TextArea;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

The next step is to extend our class as shown below:

public class ContextMenuExample extends Application {

Our class will have the following methods:

  • void main(String[] args)
  • void start(Stage primaryStage)

The next step is to define our main() method a shown below:

    public static void main(String[] args) {

Here is the full code:

package com.jenkov.javafx.contextmenu;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.ContextMenu;
import javafx.scene.control.MenuItem;
import javafx.scene.control.TextArea;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class ContextMenuExample extends Application {

    public static void main(String[] args) {
        launch(args);
    }

    public void start(Stage primaryStage) {

        ContextMenu contextMenu = new ContextMenu();
        MenuItem menuItem1 = new MenuItem("Choice 1");
        MenuItem menuItem2 = new MenuItem("Choice 2");
        MenuItem menuItem3 = new MenuItem("Choice 3");

        menuItem3.setOnAction((event) -> {
            System.out.println("Choice 3 clicked!");
        });

        contextMenu.getItems().addAll(menuItem1,menuItem2,menuItem3);

        TextArea textArea = new TextArea();

        textArea.setContextMenu(contextMenu);

        VBox vBox = new VBox(textArea);
        Scene scene = new Scene(vBox);

        primaryStage.setScene(scene);
        primaryStage.setTitle("JavaFX App");

        primaryStage.show();
    }
}
