## Implemented Interfaces

GtkViewport implements AtkImplementorIface, GtkBuildable and GtkScrollable.

## 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 GtkTable, 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. The convenience function `gtk_scrolled_window_add_with_viewport()` does exactly this, 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.

### gtk_viewport_new ()

    GtkWidget *         gtk_viewport_new                    (GtkAdjustment *hadjustment,

### gtk_viewport_set_shadow_type ()

    void                gtk_viewport_set_shadow_type        (GtkViewport *viewport,
                                                             GtkShadowType type);

Sets the shadow type of the viewport.

`viewport` : | a GtkViewport.
`type` : | the new shadow type.

### gtk_viewport_get_shadow_type ()

    GtkShadowType       gtk_viewport_get_shadow_type        (GtkViewport *viewport);

Gets the shadow type of the GtkViewport. See `gtk_viewport_set_shadow_type()`.

`viewport` : | a GtkViewport
Returns : | the shadow type

### gtk_viewport_get_bin_window ()

    GdkWindow *         gtk_viewport_get_bin_window         (GtkViewport *viewport);

Gets the bin window of the GtkViewport.

`viewport` : | a GtkViewport
Returns : | a GdkWindow. [transfer none]
