cookies comments I was going to say something in the comments about simplicity and not implementing every little bit of the rfc when we don't know of cookies that make it necessary, but then I suppose that's all implied with dillo.

  ComplexButton(int X, int Y, int W, int H, const char *L = 0);

  int value(int v);

    Returns the current value of the button (0 or 1).
  char value() const {return value_;}

    Same as \c value(1).
    \see value(int v)
  int set() {return value(1);}

    Same as \c value(0).
    \see value(int v)
  int clear() {return value(0);}

  void setonly(); // this should only be called on FL_RADIO_BUTTONs

    Returns the current shortcut key for the button.
    \retval int
  int shortcut() const {return shortcut_;}

    Sets the shortcut key to \c s.
    Setting this overrides the use of '\&' in the label().
    The value is a bitwise OR of a key and a set of shift flags, for example:
    <tt>FL_ALT | 'a'</tt>, or
    <tt>FL_ALT | (FL_F + 10)</tt>, or just
    A value of 0 disables the shortcut.

    The key can be any value returned by Fl::event_key(), but will usually be
    an ASCII letter.  Use a lower-case letter unless you require the shift key
    to be held down.

    The shift flags can be any set of values accepted by Fl::event_state().
    If the bit is on, that shift key must be pushed.  Meta, Alt, Ctrl, and
    Shift must be off if they are not in the shift flags (zero for the other
    bits indicates a "don't care" setting).
    \param[in] s bitwise OR of key and shift flags
  void shortcut(int s) {shortcut_ = s;}

    Returns the current down box type, which is drawn when value() is non-zero.
    \retval Fl_Boxtype
  Fl_Boxtype down_box() const {return (Fl_Boxtype)down_box_;}

    Sets the down box type. The default value of 0 causes FLTK to figure out
    the correct matching down version of box().
    \param[in] b down box type
  void down_box(Fl_Boxtype b) {down_box_ = b;}

  /// (for backwards compatibility)
  void shortcut(const char *s) {shortcut(fl_old_shortcut(s));}
