Hi,
Is there an event generated anywhere which I could use to test whether a region
of interest has been moved or changed? Ideally i'd be looking for an event each
time the ROI is moved or resized, I can't see an obvious way to do it at the
moment, so I wondered if anyone else has done anything like this before or if
anyone could suggest the simplest way to go about doing something like this?
Thanks
