  Enclosing class:
    ButtonBar

      public static enum ButtonBar.ButtonData
      extends Enum<ButtonBar.ButtonData>

  An enumeration of all available button data annotations. By annotating every button in a `ButtonBar` with one of these annotations, the buttons will be appropriately positioned relative to all other buttons in the ButtonBar.

  For details on the button order code for each ButtonData, refer to the javadoc comment.

  - ### Method Detail

    - #### values

          public static ButtonBar.ButtonData[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (ButtonBar.ButtonData c : ButtonBar.ButtonData.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static ButtonBar.ButtonData valueOf​(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `IllegalArgumentException` - if this enum type has no constant with the specified name
        `NullPointerException` - if the argument is null

    - #### getTypeCode

          public String getTypeCode()

      Returns the single character code used to represent the ButtonData annotation in the `button order` string.
      Returns:
        the single character code used to represent the ButtonData annotation

    - #### isCancelButton

          public final boolean isCancelButton()

      Indicates whether buttons created from the ButtonData enumeration should be the 'cancel' button in the user interface. This typically means that the button will respond to the escape key press, even if the button does not have focus.

      ButtonData enumeration values that can be the cancel button have a comment stating this in their javadoc.

      Returns:
        true if this is a 'cancel' button

    - #### isDefaultButton

          public final boolean isDefaultButton()

      Indicates whether buttons created from the ButtonData enumeration should be the 'default' button in the user interface. This typically means that the button will respond to enter key presses, even if the button does not have focus.

      ButtonData enumeration values that can be the default button have a comment stating this in their javadoc.

      Returns:
        true if this is a 'default' button
