CSS is structured in JavaFX such that you must navigate locally as you define your URL.

That means you can’t create an Image object like you can in Java code.

The url() CSS function require you to specify a URL as a string.

That gives the button the following general appearance:

The default graphic position when one isn’t specified is on the left hand side of the text.

Just make sure to specify the object within the created.

If you want to be able to define the layout entirely in FXML, it’s also possible to set the graphic of a button using the element within the object. Obviously in this example the Java code uses the annotation you’ll need to reference a Button with the fx:id of button inside the FXML file. ImageView imageView = new ImageView(getClass().getResource('/com/edencoding/images/EdenCodingIcon.png').toExternalForm()) The usual place to do this is in the initialize() method of the scene’s controller. To set an image on a button, we just need to create an ImageView and add it to the Button using the setGraphic() method of the button object. The functionality to add an image to a button is actually built into JavaFX! But JavaFX being predictable it’s just not listed as an ‘image’… That’s mostly because the functionality is intended to be more flexible – basically allowing any Node to be added as a ‘graphic’, but the overall effect can be a little confusing. Plus, I’ll show you how to achieve these using Java-only, FXML-only and CSS-only approaches.

Here are a few of the simplest layouts possible, which will be covered in this article: JavaFX gives developers a lot of functionality with both adding and positioning buttons in JavaFX. What sort of functionality you’ll achieve
