説明

A GtkViewport provides scrolling capabilities to widgets that don't support native scrolling. E.g., a GtkLabel or a GtkVBox could be packed into a GtkScrolledWindow, but since the classes don't support the "set-scroll-adjustments" signal, using the scrollbars wouldn't work.

A viewport also takes care to show only a certain part of the widget, hiding the rest of it that is not in the visible area.
