libglade - scrolled windows - drawing canvas

[Yiannis <odysseus lost gmail com>]

Hi,

I am using glade with libglade for the gtk interfaces. I have a
scrollable window with a drawing window.  But sr imply it doesn't
work.

1. during runtime program complains that: 
 Gtk-WARNING **: gtk_scrolled_window_add(): cannot add non scrollable
widget use gtk_scrolled_window_add_with_viewport() instead

But I cannot find the documentation of gtk_scrolled_window_add().
Anyway it doesnt really matter.... is there a way to change to the
gtk_scrolled_window_add_with_viewport()?? Or is there another problem
cause the application launches correctly and works ok with zooming in
or out but there are no scrollbars.

Cheers
