Implemented Interfaces

GtkViewport implements AtkImplementorIface, GtkBuildable and GtkScrollable.

Includes

#include <gtk/gtk.h>

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 GtkGrid, 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. gtk_container_add() does this automatically if a child that does not implement GtkScrollable is added to a GtkScrolledWindow, 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.
