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 javafx.event.ActionEvent is sent. Your application can perform some action based on this event by implementing an javafx.event.EventHandler to process the javafx.event.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");
    RadioButton button2 = new RadioButton("select second");

extends ToggleButton
