tooltips for each row with GtkTreeView?

["Frank W. Miller" <fwmiller cornfed com>]

Greetings,

I have a question about the interaction between tooltips and 
GtkTreeView.  What I would like to be able to do is to have a different 
tooltips for each row.  I'd like the tooltips for each row to be some 
attributes associated with the row data.  Is this possible?

Thanks,
FM
