/**
 * A single radio button performs the same basic function as a GtkCheckButton,
 * as its position in the object hierarchy reflects. It is only when multiple
 * radio buttons are grouped together that they become a different user
 * interface component in their own right.
 *
 * Every radio button is a member of some group of radio buttons. When one is
 * selected, all other radio buttons in the same group are deselected. A
 * GtkRadioButton is one way of giving the user a choice from many options.
 *
 * Radio button widgets are created with gtk_radio_button_new(), passing NULL
 * as the argument if this is the first radio button in a group. In subsequent
 * calls, the group you wish to add this button to should be passed as an
 * argument. Optionally, gtk_radio_button_new_with_label() can be used if you
 * want a text label on the radio button.
 *
 * Alternatively, when adding widgets to an existing group of radio buttons,
 * use gtk_radio_button_new_from_widget() with a GtkRadioButton that already
 * has a group assigned to it. The convenience function
 * gtk_radio_button_new_with_label_from_widget() is also provided.
 *
 * To retrieve the group a GtkRadioButton is assigned to, use
 * gtk_radio_button_get_group().
 *
 * To remove a GtkRadioButton from one group and make it part of a new one,
 * use gtk_radio_button_set_group().
 *
 * The group list does not need to be freed, as each GtkRadioButton will remove
 * itself and its list item when it is destroyed.
 *
 * $(DDOC_COMMENT example)
 *
 * When an unselected button in the group is clicked the clicked button
 * receives the "toggled" signal, as does the previously
 * selected button.
 * Inside the "toggled" handler, gtk_toggle_button_get_active()
 * can be used to determine if the button has been selected or deselected.
