Signals
AvatarImageLoadFunc
type AvatarImageLoadFunc Source #
Arguments
| = Int32 |
|
| -> IO (Maybe Pixbuf) | Returns: the pixbuf to use as a custom avatar or
|
Deprecated: (Since version 1.2)use [methodavatar.set_loadable_icon] instead.
Callback for loading an [classavatar]'s image.
The returned Pixbuf is expected to be square with width and
height set to size. The image is cropped to a circle without any scaling or
transformation.
Since: 1.0
