/**
* 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.
