Prerequisites

ClutterScriptable requires GObject.

Known Implementations

ClutterScriptable is implemented by ClutterActor, ClutterAlpha, ClutterAnimation, ClutterAnimator, ClutterBehaviour, ClutterBehaviourDepth, ClutterBehaviourEllipse, ClutterBehaviourOpacity, ClutterBehaviourPath, ClutterBehaviourRotate, ClutterBehaviourScale, ClutterBox, ClutterCairoTexture, ClutterClone, ClutterGLXTexturePixmap, ClutterGroup, ClutterInterval, ClutterKeyframeTransition, ClutterListModel, ClutterModel, ClutterPropertyTransition, ClutterRectangle, ClutterScrollActor, ClutterStage, ClutterState, ClutterText, ClutterTexture, ClutterTimeline, ClutterTransition, ClutterTransitionGroup and ClutterX11TexturePixmap.

Description

The ClutterScriptableIface interface exposes the UI definition parsing process to external classes. By implementing this interface, a class can override the UI definition parsing and transform complex data types into GObject properties, or allow custom properties.

ClutterScriptable is available since Clutter 0.6

Functions

clutter_scriptable_set_id ()

void
clutter_scriptable_set_id (ClutterScriptable *scriptable,
                           const gchar *id_);

Sets id_ as the unique Clutter script it for this instance of ClutterScriptableIface.

This name can be used by user interface designer applications to define a unique name for an object constructable using the UI definition language parsed by ClutterScript.

Parameters

scriptable	a ClutterScriptable
id_	the ClutterScript id of the object

Since: 0.6

clutter_scriptable_get_id ()

const gchar *
clutter_scriptable_get_id (ClutterScriptable *scriptable);

Retrieves the id of scriptable set using clutter_scriptable_set_id().

Parameters

scriptable

a ClutterScriptable

Returns

the id of the object. The returned string is owned by the scriptable object and should never be modified of freed

Since: 0.6

clutter_scriptable_parse_custom_node ()

gboolean
clutter_scriptable_parse_custom_node (ClutterScriptable *scriptable,
                                      ClutterScript *script,
                                      GValue *value,
                                      const gchar *name,
                                      JsonNode *node);

Parses the passed JSON node. The implementation must set the type of the passed GValue pointer using g_value_init().

Parameters

scriptable	a ClutterScriptable
script	the ClutterScript creating the scriptable instance
value	the generic value to be set
name	the name of the node
node	the JSON node to be parsed

Returns

TRUE if the node was successfully parsed, FALSE otherwise.

Since: 0.6

clutter_scriptable_set_custom_property ()

void
clutter_scriptable_set_custom_property
                               (ClutterScriptable *scriptable,
                                ClutterScript *script,
                                const gchar *name,
                                const GValue *value);

Overrides the common properties setting. The underlying virtual function should be used when implementing custom properties.

Parameters

scriptable	a ClutterScriptable
script	the ClutterScript creating the scriptable instance
name	the name of the property
value	the value of the property

Since: 0.6

Types and Values

ClutterScriptable

typedef struct _ClutterScriptable ClutterScriptable;

ClutterScriptable is an opaque structure whose members cannot be directly accessed

Since: 0.6

struct ClutterScriptableIface

struct ClutterScriptableIface {
  void         (* set_id)              (ClutterScriptable *scriptable,
                                        const gchar       *id_);
  const gchar *(* get_id)              (ClutterScriptable *scriptable);

`get_id` ()	virtual function for getting the id of a scriptable object
`parse_custom_node` ()	virtual function for parsing complex data containers into GObject properties
`set_custom_property` ()	virtual function for setting a custom property
