Interface for icons that can be loaded as a stream.
| GTypeInterface g_iface; | The parent interface. |
| load () | Loads an icon. |
| load_async () | Loads an icon asynchronously. |
| load_finish () | Finishes an asynchronous icon load. |
GInputStream* g_loadable_icon_load (GLoadableIcon *icon, int size, char **type, GCancellable *cancellable, GError **error);
Loads a loadable icon. For the asynchronous version of this function, see g_loadable_icon_load_async().
| icon : | a GLoadableIcon. |
| size : | an integer. |
| type : | a location to store the type of the loaded icon, NULL to ignore. |
| cancellable : | optional GCancellable object, NULL to ignore. |
| error : | a GError location to store the error occuring, or NULL to ignore. |
| Returns : | a GInputStream to read the icon from. |
void g_loadable_icon_load_async (GLoadableIcon *icon, int size, GCancellable *cancellable, GAsyncReadyCallback callback, gpointer user_data);
Loads an icon asynchronously. To finish this function, see g_loadable_icon_load_finish(). For the synchronous, blocking version of this function, see g_loadable_icon_load().
| icon : | a GLoadableIcon. |
| size : | an integer. |
| cancellable : | optional GCancellable object, NULL to ignore. |
| callback : | a GAsyncReadyCallback to call when the request is satisfied |
| user_data : | the data to pass to callback function |
GInputStream* g_loadable_icon_load_finish (GLoadableIcon *icon, GAsyncResult *res, char **type, GError **error);
Finishes an asynchronous icon load started in g_loadable_icon_load_async().
| icon : | a GLoadableIcon. |
| res : | a GAsyncResult. |
| type : | a location to store the type of the loaded icon, NULL to ignore. |
| error : | a GError location to store the error occuring, or NULL to ignore. |
| Returns : | a GInputStream to read the icon from. |
