If you are a beginner with JavaFX and are wondering, “What are all these Property things anyway?”, then this is the article for you. Besides the Properties themselves, we also cover the basics of using them with Bindings and Listeners. Read this article and you should have a good idea how to start out with JavaFX Properties.

Demystifying PseudoClasses in JavaFX

nuno@n9o.xyz (Blowfish) — Mon, 24 Jan 2022 12:00:00 -0500

Pseudo Classes are the best way to handle on/off state changes in a Node in JavaFX. But it’s very badly explained in the JavaDocs and hard to understand. This article should clear that up.

TextFields and TextFormatter - Part 1

nuno@n9o.xyz (Blowfish) — Tue, 11 May 2021 12:00:00 -0500

An introduction to TextFormatter, showing you how to integrate it into a TextField and how to use it to convert the input from String to some other kind of value. Then we’ll look at how to add a filter to prevent the user from entering invalid data.

Guide To the Observable Classes - Part II

nuno@n9o.xyz (Blowfish) — Thu, 22 Aug 2024 12:00:00 -0500

This article is about the all of the typed observable classes and interfaces except the ones concerned with List.

You’ll find that all of the relationships and structure found in the generic classes is just about exactly the same, but then there are a few extra classes and interfaces added to the hierarchy depending on the type of data that they hold. We’ll concentrate mostly on two types, String and Integer here, because dealing with the others would just be redundant. String is typical of stand-alone types, and Integer is typical of types that are included in Number.

TextFields and TextFormatter - Part 2

A more in-depth look into how to build a TextFormatter that can be used to turn a TextField into sophisticated input field. We’ll look at designing a TextFormatter that is tailored to handle fixed place decimal input, using the decimal point itself as a control to toggle between the ordinal and mantissa of the number.

Converting FXML to Code

nuno@n9o.xyz (Blowfish) — Tue, 22 Jul 2025 12:00:00 -0500

Introduction
#

Recently, I posted an article titled, Should You Use FXML?. In that article, I stated that I felt that well written and organized code would always be easier to maintain than any corresponding FXML/FXML Controller would be. I did not emphasize this, as the article was intended to be a discussion about the merits and costs of using FXML more than as a “is this better than this?”, exploration.

Should You Use FXML?

nuno@n9o.xyz (Blowfish) — Mon, 10 Mar 2025 12:00:00 -0500

Introduction
#

From time to time the question about, “To FXML or not to FXML” comes up on Reddit and other social media, and I’m know as being firmly in the “Not FXML” camp. I’ve had a few people message me about this, so I thought it might be a good time to examine this topic in depth.

How to Write a JavaFX Screen without FXML & Scene Builder

nuno@n9o.xyz (Blowfish) — Tue, 24 Aug 2021 12:00:00 -0500

Way, way back in 2014 when I started learning JavaFX, I tried using Scene Builder and FXML and found it to be an amazing waste of time and effort. One of the best decisions I ever made was to abandon it early on, and just code screens by hand. I advise everyone else to do the same.

Implementing MVC in JavaFX

nuno@n9o.xyz (Blowfish) — Tue, 11 May 2021 12:00:00 -0500

Model-View-Controller is generally accepted as a good way to structure an application with a user interface. While JavaFX contains all of the classes needed to implement MVC in a natural and seamless way, it doesn’t seem to be widely documented and there’s little evidence on the Web that many people have figured out how to do it properly. The fact that JavaFX supports Reactive programming makes a big difference to how you should implement MVC.
