By |June 18th, 2018|JavaFX, Tips & Tricks|0 Comments

Back in the days when I was still implementing UIs in Swing I used to be a big fan of MigLayout ("one layout manager to rule them all", right Mikael?). One of the features I really liked was the possibility to define different behaviors when a component became invisible. MigLayout allowed me to either preserve [...]

I am happy to announce that CalendarFX has found a new home on GitHub. As of today it is no longer a commercial product but an open source project. Over the last two years I have noticed that the developer community has resisted to use CalendarFX for their projects as the source code was not [...]

The same is true for applications running on MacOS X. Below you can see a snapshot of Apple's calendar app. You will notice that the scrollbar is [...]

JavaFX Tip 27: HiRes / Retina Icons

By |August 29th, 2017|JavaFX, Tips & Tricks|1 Comment

I recently had a lot of icons sent to me by a graphics / UX designer. It was my job to add them to a JavaFX application. Each icon was shipped in three sizes (16x16, 32x32, 64x64). The naming convention for them was like this: icon-name.png icon-name@2x.png icon-name@3x.png At first I thought that this was [...]

I am a big fan of IntelliJ IDEA and use it every day for the various projects I work on. One thing I like a lot is the dark theme called "Darcula". I like it because it looks cool and because of the low contrast it is better for my eyes. When you stare at [...]

BREAKING NEWS: this bug is now officially being tracked in the Java bug tracker. I noticed today that the delta values provided by the JavaFX ScrollEvent object seem to be invalid at the end of the scroll event cycle.
