This code shows how you can use clipping in JavaFX in combination with the alpha channel to implement fade in / out effects (not animations).

A little demo showing how the "visible" and "managed" property can be used to make a node disappear in such a way that the layout pane / container can reclaim the space previously occupied by the now invisible node.
