Creating Custom JavaFX Controls

Are you tired of using the same old JavaFX controls in your desktop applications? Do you want to create something unique and eye-catching? Well, you're in luck! In this article, we'll be discussing how to create custom JavaFX controls that will make your application stand out from the rest.

What are JavaFX Controls?

JavaFX controls are pre-built UI components that are used to create desktop applications. These controls include buttons, text fields, labels, and more. While these controls are great for basic applications, they can become repetitive and boring when used in more complex projects.

Why Create Custom JavaFX Controls?

Creating custom JavaFX controls allows you to add unique functionality and design to your application. It also allows you to create a consistent look and feel throughout your application. Custom controls can be used to display data in a new and interesting way, or to add new functionality to your application.

Getting Started

Before we dive into creating custom JavaFX controls, let's make sure we have everything we need. First, make sure you have the latest version of Java installed on your computer. Next, you'll need to download and install the JavaFX SDK. Once you have these installed, you're ready to start creating custom controls.

Creating a Custom Control

To create a custom control, we'll need to extend an existing JavaFX control. In this example, we'll be creating a custom button that changes color when it's clicked.

public class ColorButton extends Button {

    public ColorButton(String text) {
        setOnAction(event -> {
            Random random = new Random();
            int red = random.nextInt(256);
            int green = random.nextInt(256);
            int blue = random.nextInt(256);
            setBackground(new Background(new BackgroundFill(Color.rgb(red, green, blue), CornerRadii.EMPTY, Insets.EMPTY)));

In this code, we're extending the Button class and adding a new constructor that takes a String parameter. We're also setting an action listener on the button that changes the background color to a random RGB value when the button is clicked.

Using the Custom Control

Now that we've created our custom control, let's use it in our application. To do this, we'll need to add it to our scene graph.

public class Main extends Application {

    public void start(Stage primaryStage) throws Exception{
        ColorButton colorButton = new ColorButton("Click me!");
        VBox root = new VBox(colorButton);
        Scene scene = new Scene(root, 300, 275);

    public static void main(String[] args) {

In this code, we're creating an instance of our custom control and adding it to a VBox. We're then creating a new Scene with the VBox as the root node and setting it as the primary stage's scene.


Creating custom JavaFX controls allows you to add unique functionality and design to your desktop applications. By extending existing JavaFX controls, you can create new and interesting UI components that will make your application stand out from the rest. So, what are you waiting for?
