| Loads an icon asynchronously. | |
| 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().
|
a GLoadableIcon. |
|
an integer. |
|
a location to store the type of the
loaded icon, NULL to ignore. [out][allow-none]
|
|
optional GCancellable object, NULL to ignore. [allow-none]
|
|
a GError location to store the error occuring, or NULL to
ignore. |
Returns : |
a GInputStream to read the icon from. [transfer full] |
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().
|
a GLoadableIcon. |
|
an integer. |
|
optional GCancellable object, NULL to ignore. [allow-none]
|
|
a GAsyncReadyCallback to call when the request is satisfied. [scope async] |
|
the data to pass to callback function. [closure] |
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().
|
a GLoadableIcon. |
|
a GAsyncResult. |
|
a location to store the type of the loaded icon, NULL to ignore. |
|
a GError location to store the error occuring, or NULL to
ignore. |
Returns : |
a GInputStream to read the icon from. [transfer full] |
