Tool | regionmanager |
This function returns the ``select callback'' function (set with the function setselectcallback). It is part of the communications between the Regionmanager and the region-of-interest entry widget. If you have not set a callback function, this function returns 0.
It is not intended for general purpose use and you will break some communications if you mess with these functions.
