    public class RadioButton
extends ToggleButton

    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);

      Returns:
      new instance of default skin for this control. If null then the control will have no skin unless one is provided by css.

    • getInitialAlignment

      protected Pos getInitialAlignment()
      Returns the initial alignment state of this control, for use by the JavaFX CSS engine to correctly set its initial value. This method is overridden to use Pos.CENTER_LEFT initially.
      Overrides:
      getInitialAlignment in class ToggleButton
      Returns:
      the initial alignment state of this control

    • queryAccessibleAttribute

      public Object queryAccessibleAttribute​(AccessibleAttribute attribute,
                                       Object... parameters)
      This method is called by the assistive technology to request the value for an attribute.

      This method is commonly overridden by subclasses to implement attributes that are required for a specific role.
      If a particular attribute is not handled, the superclass implementation must be called.

      Overrides:
      queryAccessibleAttribute in class ToggleButton
      Parameters:
      attribute - the requested attribute
      parameters - optional list of parameters
      Returns:
      the value for the requested attribute
