struct RadioItem : Action {
  function<void ()> onActivate;

  static void group(const RadioItem&... items);

  bool checked();
  void setChecked();
  void setText(const string &text);
};

function<void ()> RadioItem::onActivate;

Called when a radio item is set to the active item in a group. Does not get called if item is selected but is already active. Does not get called if a radio item loses its active state.

static void RadioItem::group(const RadioItem&... items);

bool RadioItem::checked();

True if the radio item is currently the active item in the group.

void RadioItem::setChecked();

Sets this radio item to the active item in the group.
