IconName,
Gicon,
Surface,
// some variants omitted
}
Expand description
Describes the image data representation used by a Image
. If you
want to get the image from the widget, you can only get the
currently-stored representation. e.g. if the
ImageExt::storage_type()
returns Pixbuf
, then you can
call ImageExt::pixbuf()
but not gtk_image_get_stock()
. For empty
images, you can request any storage type (call any of the “get”
functions), but they will all return None
values.
Variants (Non-exhaustive)
This enum is marked as non-exhaustive
Empty
there is no image displayed by the widget
Pixbuf
the widget contains a gdk_pixbuf::Pixbuf
Stock
the widget contains a [stock item name][gtkstock]
IconSet
the widget contains a GtkIconSet
Animation
the widget contains a gdk_pixbuf::PixbufAnimation
IconName
the widget contains a named icon. This image type was added in GTK+ 2.6
Gicon
the widget contains a gio::Icon
.
This image type was added in GTK+ 2.14
Surface
the widget contains a cairo::Surface
.
This image type was added in GTK+ 3.10
