-/**
- * @defgroup Radio Radio
- *
- * The radio button allows for 1 or more selectors to be created to select 1
- * of a set of options.
- *
- * Signals that you can add callbacks for are:
- *
- * changed - This is called whenever the user changes the state of one of the
- * radio objects within the group of radio objects that work together.
- *
- * A radio object contains an indicator, an optional Label and an optional
- * icon object. They work normally in groups of 2 or more. When you create a
- * radio (if it is not the first member of the group), simply add it to the
- * group by adding it to any other member of the group that already exists
- * (or the first member) with elm_radio_group_add() with the second parameter
- * being the existing group member. The radio object(s) will select from one
- * of a set of integer values, so any value they are configuring needs to be
- * mapped to a set of integers. To configure what value that radio object
- * represents, use elm_radio_state_value_set() to set the integer it
- * represents. To set the value the whole group is to indicate use
- * elm_radio_value_set() on any group member, and to get the groups value use
- * elm_radio_value_get(). For convenience the radio objects are also able to
- * directly set an integer (int) to the value that is selected. To specify
- * the pointer to this integer to modify, use elm_radio_value_pointer_set().
- * The radio objects will modify this directly. That implies the pointer must
- * point to valid memory for as long as the radio objects exist.
