GtkPreview implements AtkImplementorIface and GtkBuildable.

The GtkPreview widget provides a simple interface used to display images as RGB or grayscale data. It's deprecated; just use a GdkPixbuf displayed by a GtkImage, or perhaps a GtkDrawingArea. GtkPreview has no advantage over those approaches.

GtkPreview

WARNING: GtkPreview is deprecated and should not be used in newly-written code. The GtkPreview struct contains private data only, and should be accessed using the functions below.

GtkPreviewInfo

WARNING: GtkPreviewInfo is deprecated and should not be used in newly-written code. Contains information about global properties of preview widgets. The GtkPreviewInfo struct contains the following fields. (These fields should be considered read-only. They should never be set by an application.)

`GdkVisual` *visual;	the visual used by all previews.
`GdkColormap` *cmap;	the colormap used by all previews.
gdouble gamma;	the gamma correction value used by all previews (See `gtkPreviewSetGamma` ).
