treeview selected row signal

[anguila <anguila gmail com>]

I have a treeview and when I click to one of those rows with the signal cursor-changed I can change the name of a label. Also I have 2 buttons, the first one to add a new row to the treeview and the other to remove rows. When I remove a selected row I select the row before (widget->select).
When I click to the row it works, it changes the label, but when i click to the remove button, only select the row before and doesn't change the label.
How can I activate the cursor changed signal when I select a row with ->select? Or is a selected row signal or atleast something like that? 

Thanks again.

David :)
