public class InfoOverlay
extends javafx.scene.control.Control

A simple UI control that allows for an information popup to be displayed over a node to describe it in further detail. In some ways, it can be thought of as a always visible tooltip (although by default it is collapsed so only the first line is shown - clicking on it will expand it to show all text).

Shown below is a screenshot of the InfoOverlay control in both its collapsed and expanded states:
