Detailed Description

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.

Structures

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 ).

Convenient Construction

gtkPreview is the equivalent of gtkPreviewNew.
