Large amount of rows in a TreeView list.

[csld skynet be]

Hello,

My application should display big database tables in a TreeView list 
(~10000 rows).
Because, in this case, calling the append method of Gtk2::ListStore for 
each row is not very efficient, I would like to avoid to copy result 
sets in this list model.

To solve this problem, the MFC CListLiew control has a callback 
mechanism asking to application row data to display for only visible 
rows in the list.

To have the same effect in GTK2, I think it's necessary to subclass the 
Gtk2::TreeModel. But that seems me complex.

Do you know a better way or where I can find code samples demonstrating 
how to subclass the Gtk2::TreeModel?

Thank you for your help.

Regards,
