/**
 * PikaIntRadioFrameSensitivityFunc:
 * @value: the value associated with a radio button.
 * @user_data: the data associated with a radio button.
 * @new_value: the value to check instead if the function returns %FALSE.
 * @data: (closure): the data set in pika_int_radio_frame_set_sensitivity()
 *
 * Signature for a function called on each radio button value and data,
 * each time the %PikaIntRadioFrame is drawn, to make some radio button
 * insensitive.
 * If the function returns %FALSE, it usually means that the value is
 * not a valid choice in current situation. In this case, you might want
 * to toggle instead another value automatically. Set @new_value to the
 * value to toggle. If you leave this untouched, the radio button will
 * stay toggled despite being insensitive. This is up to you to decide
 * whether this is meaningful.
 *
 * Returns: %TRUE if the button stays sensitive, %FALSE otherwise.
