enlarge the scrollable area

[Stefano Facchini <stefano facchini gmail com>]

Hi,

I'm trying to build a scrolled window in a such a way that the child 
widget has always the same size, regardless of the size of the scrolled 
window itself. I tried gtk_scrolled_window_set_min_content_width, but 
this also sets the minimum size of the scrolled window. Basically, I 
need something to force the size of the child widget (for example a 
TextView), or to enlarge the scrollable area without enlarging the 
scrolled window. Is it possible to have this behavior?

thank you!
