Is there a viewport selection - Python question

[mrhumbility]

Hey,

I am trying to do some stuff in python with viewport selections. I want to query whether or not the user has anything selected, not necessarily get what is already selected. As far as I can tell the only way to do anything with the viewport is through toolutils. If I use "toolutils.sceneViewer().selectGeometry()" and nothing is selected, it waits until the user hits enter over the viewport before continuing. Is there any way to simply return whether or not any geometry has been selected without having to wait for the user to hit enter?

import toolutils

sv = toolutils.sceneViewer()
geo = sv.selectGeometry()
if geo:
    print "There is a selection"
else:
    print "No geo selected"

Thanks!
