ScrolledWindow can only scroll scrollable widgets, such as TextView
and TreeView. For widgets that are not scrollable, you can put them
into a Viewport container. You can either create and add the Viewport
explicitly, then add the label to the Viewport, or use the
AddWithViewport convenience method.

sw.AddWithViewport (lbl);
