GtkTreeView rows-reorderd signal

[SkyRat23 aol com]

Hello.  I have searched the mailing lists and found no answer to this question.  I would like to "catch" when 
a drag and drop has been done on a TreeView, hence running an function when the TreeView's rows have been 
reordered.  However, the signal (rows-reordered) is never emmited.  Someone correct me if I am wrong, but if 
rows in the TreeView are reordered from a drang and drop event the "rows-reordered" signal should be 
emmitted, correct?  I am connecting the 'rows-reordered' signal to my treeview but it is never invoked.  
Anyone have ideas,  Experienced this before?  Or how about another signal that I could connect to that would 
also be emmitted from a drag and drop on a TreeView.

Thanks.
