GUI wxHaskell database table in grid

Question

Hello,

I'm writing GUI app in haskell.

I use sqlite to gather data and want to use grid in wxHASKELL TO present data in app. Everything is all right but I want to have possibility to add rows from haskell app. I achieved that but when I refresh it It expands and covers other controls.

To make things short how can I set maximum size of control, and if there are more rows in that grid then make scroll appear ?

thanks for any help, bye
