Manage the speed in a scrolling text control ? (1 Viewer)

[zebons]

hello,

I'm writing a new pluging (use directly an ANT Movie Catalog Database in MP).
I have a question : in a Scrolling Text Control (GUITextScrollUpControl), is it possible to manage the speed of the scrolling text ? And how ?
Directly in the skin definition with a specific tag for that control ?
or/and thru C# code ?
Thanks for responses
