GtkTree cursor scoping

["Hassaan Khan" <hkhan cmu edu>]

I have 2 tree views.
TreeView1: is an editable GtkTreeStore that allows the user to change the values
TreeView2: is a display that shows data being sent over a network

The problem is that when during updating TreeView1, if more data comes in, I have to update the screen to 
keep the most recent data in there, but at the same time, I lose scope of the cursor, when data input isn't 
complete, and hence have to click on TreeView1 again to get to the correct entry point. This is really 
irritating.
I've followed the GtkTree Tutorial at: http://scentric.net/tutorial/ but haven't found much about the scoping 
of the cursor and hence solving the problem.

So my questions are:

1. is it possible for the cursor not to move during an update for TreeView2 while the update also happens?
If not how do i make sure that the cursor returns to the correct TreeView after an update?

Any help on this would be greatly appriciated.
Thank you
