The 'GI.Gtk.Objects.Viewport.Viewport' 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
'GI.Gtk.Objects.Grid.Grid', 'GI.Gtk.Objects.Box.Box', and so on.

If a widget has native scrolling abilities, such as 'GI.Gtk.Objects.TextView.TextView',
'GI.Gtk.Objects.TreeView.TreeView' or 'GI.Gtk.Objects.IconView.IconView', it can be added to a 'GI.Gtk.Objects.ScrolledWindow.ScrolledWindow'
with 'GI.Gtk.Objects.Container.containerAdd'. If a widget does not, you must first add the
widget to a 'GI.Gtk.Objects.Viewport.Viewport', then add the viewport to the scrolled window.
'GI.Gtk.Objects.Container.containerAdd' does this automatically if a child that does not
implement 'GI.Gtk.Interfaces.Scrollable.Scrollable' is added to a 'GI.Gtk.Objects.ScrolledWindow.ScrolledWindow', so you can
ignore the presence of the viewport.

The GtkViewport will start scrolling content only if allocated less
than the child widget’s minimum size in a given orientation.

= CSS nodes

GtkViewport has a single CSS node with name viewport.
