first off i would use a different instance variable besides "GUI".
Could be AG or auditorgui.
Also the conditional "if len(dirname ) > 0:" could simply be "if
dirname:"
When you ask for the attribute currentdir are you asking as
"GUI.currentdir.get()" or "GUI.currentdir"???
only the second will work with a TKVAR, but there is really no need to
use a TKVAR here. I would simply do:
self.currentdir = None
then you could say:
if GUI.currentdir:
do this()
