[Gtk-sharp-list] How to display data from a SQLite database into a GTK# TreeView?

[NPcomplete]

Hi,

Thanks this was really nice! I had reached the conclusion that I need to
write my own version of the tree  model, but you just saved me a lot of
work, I really appreciate it.
As far as the other error, I found out the problem (I think): the cell
renderer reference when creating the column and when adding a cell to
display data must be the same. Interestingly enough, it worked if I used one
object reference for all the cells throughout the table. I guess I just need
to read more into the GTK+ documentation.

Thank you again.

Kiril.
