clutter_transition_get_interval

Retrieves the interval set using clutter_transition_set_interval().

clutter_transition_get_remove_on_complete

Retrieves the value of the ClutterTransition:remove-on-complete property.

clutter_transition_set_from

Sets the initial value of the transition.

clutter_transition_set_from_value

Sets the initial value of the transition.

clutter_transition_set_interval

Sets the ClutterTransition:interval property using interval.

clutter_transition_set_remove_on_complete

Sets whether transition should be detached from the ClutterAnimatable set using clutter_transition_set_animatable() when the ClutterTimeline::completed signal is emitted.

clutter_transition_set_to

Sets the final value of the transition.

clutter_transition_set_to_value

Properties

Clutter.Transition:animatable

The ClutterAnimatable instance currently being animated.

Clutter.Transition:interval

The ClutterInterval used to describe the initial and final states of the transition.

Clutter.Transition:remove-on-complete

Whether the ClutterTransition should be automatically detached from the ClutterTransition:animatable instance whenever the ClutterTimeline::stopped signal is emitted.

Properties inherited from ClutterTimeline (8)

Clutter.Timeline:actor

No description available.

Clutter.Timeline:auto-reverse

If the direction of the timeline should be automatically reversed when reaching the end.

Clutter.Timeline:delay

A delay, in milliseconds, that should be observed by the timeline before actually starting.

Clutter.Timeline:direction

The direction of the timeline, either CLUTTER_TIMELINE_FORWARD or CLUTTER_TIMELINE_BACKWARD.

Clutter.Timeline:duration

Duration of the timeline in milliseconds, depending on the ClutterTimeline:frame-clock value.

Clutter.Timeline:frame-clock

The frame clock driving the timeline.

Clutter.Timeline:progress-mode

Controls the way a ClutterTimeline computes the normalized progress.

Clutter.Timeline:repeat-count

Defines how many times the timeline should repeat.

Signals

Signals inherited from ClutterTimeline (6)

ClutterTimeline::completed

The signal is emitted when the timeline’s elapsed time reaches the value of the ClutterTimeline:duration property.

ClutterTimeline::marker-reached

The signal is emitted each time a timeline reaches a marker set with clutter_timeline_add_marker_at_time().

ClutterTimeline::new-frame

The signal is emitted for each timeline running timeline before a new frame is drawn to give animations a chance to update the scene.

ClutterTimeline::paused

The signal is emitted when clutter_timeline_pause() is invoked.

ClutterTimeline::started

The signal is emitted when the timeline starts its run. This might be as soon as clutter_timeline_start() is invoked or after the delay set in the ClutterTimeline:delay property has expired.

ClutterTimeline::stopped

The signal is emitted when the timeline has been stopped, either because clutter_timeline_stop() has been called, or because it has been exhausted.

Signals inherited from GObject (1)

GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Class members

attached: void (* attached) ( ClutterTransition* transition, ClutterAnimatable* animatable ): Virtual function; called when a transition is attached to a ClutterAnimatable instance.
detached: void (* detached) ( ClutterTransition* transition, ClutterAnimatable* animatable ): Virtual function; called when a transition is detached from a ClutterAnimatable instance.
compute_value: void (* compute_value) ( ClutterTransition* transition, ClutterAnimatable* animatable, ClutterInterval* interval, gdouble progress ): Virtual function; called each frame to compute and apply the interpolation of the interval.
