All Implemented Interfaces:

PointerInterface

public class Viewport
extends Widget

`GtkViewport` implements scrollability for widgets that lack their
own scrolling capabilities.

Use `GtkViewport` to scroll child widgets such as `GtkGrid`,
`GtkBox`, and so on.

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`.

# Accessibility

`GtkViewport` uses the %GTK_ACCESSIBLE_ROLE_GROUP role.
