Viewport

public sealed class Viewport : Widget, Accessible, Buildable, ConstraintTarget, Scrollable

`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.

`GtkViewport` has a single CSS node with name `viewport`.

Until GTK 4.10, `GtkViewport` used the `GTK_ACCESSIBLE_ROLE_GROUP` role.

Starting from GTK 4.12, `GtkViewport` uses the `GTK_ACCESSIBLE_ROLE_GENERIC` role.
