/**
 * Description
 * The GtkViewport widget acts as an adaptor class, implementing
 * scrollability for child widgets that lack their own scrolling
 * capabilities. Use GtkViewport to scroll child widgets such as
 * GtkTable, GtkBox, and so on.
 * If a widget has native scrolling abilities, such as GtkTextView,
 * GtkTreeView or GtkIconview, it can be added to a GtkScrolledWindow
 * with gtk_container_add(). If a widget does not, you must first add the
 * widget to a GtkViewport, then add the viewport to the scrolled window.
 * The convenience function gtk_scrolled_window_add_with_viewport() does
 * exactly this, so you can ignore the presence of the viewport.
