Interface for icons that can be loaded as a stream.
GTypeInterface |
The parent interface. |
|
Loads an icon. |
|
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.
|
|
optional GCancellable object, NULL to ignore.
|
|
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().
|
a GLoadableIcon. |
|
an integer. |
|
optional GCancellable object, NULL to ignore.
|
|
a GAsyncReadyCallback to call when the request is satisfied |
|
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().
|
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. |
