Recently and with the help of my coworker Scavenger156, I implemented a nice animation to show interactions between two tables in JavaFX. In our application it is possible to give special permissions to users. Hence, there is a set of users who have these permissions and there is a set of users who don't. A user can just be in one of these sets. To make assigning user to these sets easy and intuitive, we came up with the following component:

There have been a lot of changes in the last months. My work as an employed software developer kind of got to a new level because of the changes in my project.

For my last JavaFX articles, I wanted to show the animated results directly at this website. At the time being, there's no guarantee that a visitor can execute an embedded JavaFX application.

So I searched for a simple solution to display screen capture footage directly at a website. Despite it's bad reputation, an animated gif works on every browser I know.

At MouseOver, the pane expands and shows the button texts. One button can then be choosen and is highlighted with a drop shadow.

Here's the code as a SSCCE.

This is the controller ExtendableNavigation.java:

Extendable search pane in JavaFX

Yesterday, I implemented an extendable search pane in JavaFX. Having searched the web for a ready to use component, I found that most of the search panes hover above other nodes. But what if I want to extend the search pane by resizing other nodes, for example the results table? That is the only way to see all search results and all search options at the same time. This is what I build:
