ClutterTransition is a subclass of ClutterTimeline that computes the interpolation between two values, stored by a ClutterInterval.
void clutter_transition_set_interval (ClutterTransition *transition,ClutterInterval *interval);
Sets the “interval” property using interval
.
The transition
will acquire a reference on the interval
, sinking
the floating flag on it if necessary.
Since 1.10
ClutterInterval *
clutter_transition_get_interval (ClutterTransition *transition);
Retrieves the interval set using clutter_transition_set_interval()
a ClutterInterval, or NULL; the returned
interval is owned by the ClutterTransition and it should not be freed
directly.
[transfer none]
Since 1.10
void clutter_transition_set_animatable (ClutterTransition *transition,ClutterAnimatable *animatable);
Sets the “animatable” property.
The transition
will acquire a reference to the animatable
instance,
and will call the ClutterTransitionClass.attached() virtual function.
If an existing ClutterAnimatable is attached to transition
, the
reference will be released, and the ClutterTransitionClass.detached()
virtual function will be called.
Since 1.10
ClutterAnimatable *
clutter_transition_get_animatable (ClutterTransition *transition);
Retrieves the ClutterAnimatable set using clutter_transition_set_animatable().
a ClutterAnimatable, or NULL; the returned
animatable is owned by the ClutterTransition, and it should not be freed
directly.
[transfer none]
Since 1.10
void clutter_transition_set_remove_on_complete (ClutterTransition *transition,gboolean remove_complete);
Sets whether transition
should be detached from the ClutterAnimatable
set using clutter_transition_set_animatable() when the
“completed” signal is emitted.
Since 1.10
gboolean
clutter_transition_get_remove_on_complete
(ClutterTransition *transition);
Retrieves the value of the “remove-on-complete” property.
Since 1.10
typedef struct _ClutterTransition ClutterTransition;
The ClutterTransition structure contains private data and should only be accessed using the provided API.
Since 1.10
struct ClutterTransitionClass {
void (* attached) (ClutterTransition *transition,
ClutterAnimatable *animatable);
void (* detached) (ClutterTransition *transition,
ClutterAnimatable *animatable);
void (* compute_value) (ClutterTransition *transition,
ClutterAnimatable *animatable,
ClutterInterval *interval,
gdouble progress);
};
The ClutterTransitionClass structure contains private data.

Since 1.10
“animatable” property“animatable” ClutterAnimatable *
The ClutterAnimatable instance currently being animated.
Flags: Read / Write
Since 1.10
“interval” property“interval” ClutterInterval *
The ClutterInterval used to describe the initial and final states of the transition.
Flags: Read / Write
Since 1.10
“remove-on-complete” property “remove-on-complete” gboolean
Whether the ClutterTransition should be automatically detached from the “animatable” instance whenever the “completed” signal is emitted.
The “remove-on-complete” property takes into account the value of the “repeat-count” property, and it only detaches the transition if the transition is not repeating.
Flags: Read / Write
Default value: FALSE
