Debugging BentoFX in MelodyMatrix with Matt Coley, Scenic View, and an Honest Look at AI-Generated Code

Tue, 21 Apr 2026 00:00:00 +0000

There are bugs you can solve by yourself, and bugs where you just need to sit down with someone who knows the internals. This video is in the second category. MelodyMatrix uses BentoFX for its dockable panel layout. Branches, leaves, tabs on the side, content panels that open and close. It works well until something fights the layout. But I had some visual problems I could not explain, some code that felt more complicated than it should be, and no good explanation for why.

MelodyMatrix V1.0.0 Released: Shipping a JavaFX App with jDeploy, GitHub Actions, and Auto-Update

Thu, 16 Apr 2026 00:00:00 +0000

Some side projects take a while to get to a proper release. MelodyMatrix is one of those. The app has been downloadable for quite some time thanks to jDeploy , but there was no official V1.0.0 yet. No tagged release. No moment of “okay, this is it.” Just a rolling build on every commit to the main branch.

JavaFX In Action #23 with Craig Raw about the Sparrow Bitcoin Wallet

Thu, 20 Nov 2025 00:00:00 +0000

I don’t have any bitcoin myself, but still find the idea of the blockchain and “public shared money” fascinating. And as it turns out, there is a free and open-source bitcoin wallet, created with JavaFX, that wants to help people understand how the Bitcoin system works, and make transactions easy to understand. Thanks to the work of Craig Raw, there is an easy-to-use desktop application to create and manage wallets. And while he explains the app itself, we also learn a lot about the Bitcoin ecosystem, reproducible builds, security, hardware wallets, and more!

For my next JavaFX In Action interview, I talked with Matt Coley about Recaf and the JavaFX libraries he’s working on. But unexpectedly, I got a deep-dive course on Java byte code, obfuscated code, and how JARs can be (ab)used to hide the real code they are executing…!

JavaFX In Action #21 with Vlad Protsenko, Combining Clojure with JavaFX for Game Development with Defold

Thu, 16 Oct 2025 00:00:00 +0000

Vlad Protsenko is a Clojure developer working at Defold. While I initially wanted to learn about the Cljfx project, our conversation evolved into a learning experience: a practical getting-started guide to Clojure, a hands-on demonstration of building JavaFX user interfaces with minimal code, and an inside look at the Defold game engine and its JavaFX-based IDE.

Live Stream Coding: Improving the Vaadin+Spring+Pi4J demo application with Matti Tahvonen

Tue, 23 Sep 2025 00:00:00 +0000

During a live stream coding session, Matti Tahvonen and I updated an existing Vaadin+Spring+Pi4J demo application to use the latest version of the libraries and Java 25. It’s a demo application I created a few years ago to using during presentations at conferences. Of course, everything evolves, so a big update and refactoring was needed.

Thu, 19 Dec 2024 00:00:00 +0000

Jago de Vreede is bringing SDKMAN to Windows! He builds a user interface on top of the terminal tool to make it easier to use, and add the same time solves the problem that you could only use SDKMAN on Linux and macOS. In the previous “JFX In Action” interview we saw how jDeploy can be used to distribute a JavaFX application, and in this one we see how you can achieve the same with GraalVM, although it is more difficult to setup. In the video, he walks us through the GitHub Actions that he created to build those native binaries. Jago also shows us how he uses SceneBuilder to create the layout of the app.
