JavaFX: BeforeAfterView
The BeforeAfterView is a new control in the GemsFX library. It provides a functionality that has been used for web pages for quite some time. Two nodes can be added to it and a slider / divider allows the user to see more or less of either nodes. In most cases the nodes will be simple images / image views. But developers can choose any JavaFX node they like. In the second part of the video one can see a settings UI before and after it has been completely styles.
