I have added a new "StretchingTilePane" container to #GemsFX 3.6.1 so that I can finally create a nice responsive tile-based layout for the module selection view of our CRM solution. The default #JavaFX TilePane does not fill the available width. #java #ui #ux

Chasing memory leaks in my #JavaFX based application is a breeze when using JMemoryBuddy from @floriankirmaier.bsky.social github.com/Sandec/JMemo... I add it to my prod code, not just test classes. At any time I can see whether UI views got garbage collected or not.

I published an interview with Vlad Protsenko about the Cljfx project with a quick intro to #Clojure, demonstration of building a #JavaFX user interface, and an inside look at the @defold.com game engine and its JavaFX IDE.

Thanks to the new stage style EXTENDED in JavaFX 25 we now have full control over the user experience in #JavaFX applications. Together with the new HeaderBar control we can place controls in the title bar area. Add #AtlantaFX theming (including dark mode) and UIs are pro level. #java #ui #ux

I have been developing a VSCode extension to generate JavaFX builders, but I decided to rewrite it as a library for a better approach. Recognizing the library's clear potential, I chose to halt the development of the extension.

If you're on mac, please try JavaFX 26-ea+6 and share feedback. Tip: add `-Dprism.verbose=true` which will confirm you're really using metal, as shown below. Many thanks to Kevin, Ambarish, Ajit, Jayathirth and others for their great work.

"Empathy driven development" means to consider that there are users out there with disabilities. One of them is "color vision deficiency" (CVD), and today I added a preferences pane that allows our users to pick their status colours based on their CVD. #javafx #java #ui #ux
Default color palette used for the four main states shown in the UI. A status color palette for people with protanopia vision. A status color palette for people with tritanopia vision. A status color palette for people with achromatopsia vision.
