You aren't really clear here, but I'm guessing you mean you have
editable cell renderers in this tree to perform this entry/updating. If
so, you need to connect to the signal on the CellRenderer which
indicates an edit has completed, and post the data to your model.
If on the other hand, you are talking about a tree selection based
update, where you want to post something to your "backend service" when
the selected row changes, you use the TreeView.Selection object to
detect changes like that.
ListStore.RowChanged will not fire in the selection changed scenario
above, and won't fire in the CellRenderer.Edited scenario until you post
the changed value back to the ListStore.
