Class ToggleGroup

java.lang.Object

javafx.scene.control.ToggleGroup

public class ToggleGroup
extends Object

A class which contains a reference to all Toggles whose selected variables should be managed such that only a single Toggle within the ToggleGroup may be selected at any one time.

Generally ToggleGroups are managed automatically simply by specifying the name of a ToggleGroup on the Toggle, but in some situations it is desirable to explicitly manage which ToggleGroup is used by Toggles.
