In GtkAda 1.3.12 it was easy to associate data with a row in a tree thru instantiation of the package Row_Data. How is this done in GtkAda 2.2? I notice a lot of Set_* procedures/functions in Tree_*, but no Get_*. The only thing that comes close is in Tree_Selection but that assumes a selected row. I'm at a loss here. Rob Groen
