52 * GtkImageType:
53 * @GTK_IMAGE_EMPTY: there is no image displayed by the widget
54 * @GTK_IMAGE_PIXBUF: the widget contains a #GdkPixbuf
55 * @GTK_IMAGE_STOCK: the widget contains a [stock item name][gtkstock]
56 * @GTK_IMAGE_ICON_SET: the widget contains a #GtkIconSet
57 * @GTK_IMAGE_ANIMATION: the widget contains a #GdkPixbufAnimation
58 * @GTK_IMAGE_ICON_NAME: the widget contains a named icon.
59 * This image type was added in GTK+ 2.6
60 * @GTK_IMAGE_GICON: the widget contains a #GIcon.
61 * This image type was added in GTK+ 2.14
62 * @GTK_IMAGE_SURFACE: the widget contains a #cairo_surface_t.
63 * This image type was added in GTK+ 3.10
64 *
65 * Describes the image data representation used by a #GtkImage. If you
66 * want to get the image from the widget, you can only get the
67 * currently-stored representation. e.g. if the
68 * gtk_image_get_storage_type() returns #GTK_IMAGE_PIXBUF, then you can
69 * call gtk_image_get_pixbuf() but not gtk_image_get_stock(). For empty
70 * images, you can request any storage type (call any of the "get"
71 * functions), but they will all return %NULL values.
