How to determine which icon set is used

[cyberpython <cyberpython gmail com>]

Hi,
I would like to ask if there is a way (e.g. a settings file) to
determine the name of the current icon theme (e.g. Oxygen-Refit) apart
from the gconf command line tool.

(Note: I am interested to determine the icon-theme name programmatically
within Java code, so I cannot use methods involving GUI tools.)

Thanks in advance,
cyberpython.
