["emafranc libero it" <emafranc libero it>]

I'm developing an application (using gtk+ 2.2.2) that requires more than 2000 columns in a list (treview).
Inserting columns becomes more and more slow depending on the number of columns in the view.
I tried searching for solutions over the Internet, but I failed.
How can I solve this problem? Do you have any suggestion?

Thank you very much,
