Tracking element changes - as they happen?

Hi guys,

Is there a means of tracking the changes being made to an element as hey happen? ie, you click on the start point of a line, say, and as you move it, you get notified (cursor position, the element being changed etc).

Is this possible?

I know of the IChangeTrackEvents interface, but I think that only pre/post notifies you of a change event, but not as it happens (dragging etc).

 

Regards

John.
