  12     A radio box item is used to select one of number of mutually exclusive
  13     choices.  It is displayed as a vertical column or horizontal row of
  14     labelled buttons.

  16     @beginStyleTable
  17     @style{wxRA_SPECIFY_ROWS}
  18            The major dimension parameter refers to the maximum number of rows.
  19     @style{wxRA_SPECIFY_COLS}
  20            The major dimension parameter refers to the maximum number of
  21            columns.
  22     @style{wxRA_USE_CHECKBOX}
  23            Use of the checkbox controls instead of radio buttons (currently
