Class RadioButton

RadioButtons create a series of items where only one item can be selected. RadioButtons are a specialized ToggleButton. When a RadioButton is pressed and released a ActionEvent is sent. Your application can perform some action based on this event by implementing an EventHandler to process the ActionEvent.

Only one RadioButton can be selected when placed in a ToggleGroup. Clicking on a selected RadioButton will have no effect. A RadioButton that is not in a ToggleGroup can be selected and unselected. By default a RadioButton is not in a ToggleGroup. Calling ToggleGroup.getSelectedToggle() will return you the RadioButton that has been selected.

 ToggleGroup group = new ToggleGroup();
 RadioButton button1 = new RadioButton("select first");
 button1.setToggleGroup(group);
 button1.setSelected(true);
 RadioButton button2 = new RadioButton("select second");
 button2.setToggleGroup(group);
