detecting gestures

[ron barber]

Hi,
Is there a way for scrollbar objects to detect two finger swipes like
the field object does?
If that is not possible, is there a 'swipe' message sent that can be
picked up by any other object or is it OS native object related? What
I would like to do is have the scrollbar control respond to the swipe
like a field does and move across its length. Perhaps there is a
workaround? relate the thumbpos to the vscroll of a fld?

Thanks
Ron
