ClutterActorMeta is an abstract class providing a common API for modifiers of ClutterActor behaviour, appearance or layout.
A ClutterActorMeta can only be owned by a single ClutterActor at any time.
Every sub-class of ClutterActorMeta should check if the
"enabled" property is set to TRUE before applying
any kind of modification.
ClutterActorMeta is available since Clutter 1.4
typedef struct _ClutterActorMeta ClutterActorMeta;
The ClutterActorMeta structure contains only private data and should be accessed using the provided API
Since 1.4
struct ClutterActorMetaClass {
/**
* ClutterActorMetaClass::set_actor:
* @meta: a #ClutterActorMeta
* @actor: (allow-none): the actor attached to @meta, or %NULL
*
* Virtual function, called when @meta is attached or detached
* from a #ClutterActor.
*/

Since 1.4
void clutter_actor_meta_set_name (ClutterActorMeta *meta,const gchar *name);
Sets the name of meta
The name can be used to identify the ClutterActorMeta instance
|
a ClutterActorMeta |
|
the name of meta

Since 1.4
const gchar * clutter_actor_meta_get_name (ClutterActorMeta *meta);
Retrieves the name set using clutter_actor_meta_set_name()
|
a ClutterActorMeta |
Returns : |
the name of the ClutterActorMeta
instance, or NULL if none was set. The returned string is owned
by the ClutterActorMeta instance and it should not be modified
or freed. [transfer none]

Since 1.4
void clutter_actor_meta_set_enabled (ClutterActorMeta *meta,gboolean is_enabled);
Sets whether meta should be enabled or not

|
whether meta is enabled |
Since 1.4
gboolean clutter_actor_meta_get_enabled (ClutterActorMeta *meta);
Retrieves whether meta is enabled
|
a ClutterActorMeta |
Returns : |
TRUE if the ClutterActorMeta instance is enabled |
Since 1.4
ClutterActor * clutter_actor_meta_get_actor (ClutterActorMeta *meta);
Retrieves a pointer to the ClutterActor that owns meta
|
a ClutterActorMeta |
Returns : |
a pointer to a ClutterActor or NULL. [transfer none]
