clutter_transition_set_from ()

void                clutter_transition_set_from         (ClutterTransition *transition,
                                                         GType value_type,
                                                         ...);

Sets the initial value of the transition.

This is a convenience function that will either create the ClutterInterval used by transition, or will update it if the "interval" is already set.

If transition already has a "interval" set, then value must hold the same type, or a transformable type, as the interval's "value-type" property.

This is a convenience function for the C API; language bindings should use clutter_transition_set_from_value() instead.

Since 1.12

clutter_transition_set_from_value ()

void                clutter_transition_set_from_value   (ClutterTransition *transition,
                                                         const GValue *value);

Sets the initial value of the transition.

This is a convenience function that will either create the ClutterInterval used by transition, or will update it if the "interval" is already set.

This function will copy the contents of value, so it is safe to call g_value_unset() after it returns.

If transition already has a "interval" set, then value must hold the same type, or a transformable type, as the interval's "value-type" property.

This function is meant to be used by language bindings.

Rename to: clutter_transition_set_from

clutter_transition_set_to ()

void                clutter_transition_set_to           (ClutterTransition *transition,
                                                         GType value_type,
                                                         ...);

Sets the final value of the transition.

This is a convenience function that will either create the ClutterInterval used by transition, or will update it if the "interval" is already set.

If transition already has a "interval" set, then value must hold the same type, or a transformable type, as the interval's "value-type" property.

This is a convenience function for the C API; language bindings should use clutter_transition_set_to_value() instead.

Since 1.12

clutter_transition_set_to_value ()

void                clutter_transition_set_to_value     (ClutterTransition *transition,
                                                         const GValue *value);

clutter_transition_set_interval ()

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

clutter_transition_get_interval ()

ClutterInterval *   clutter_transition_get_interval     (ClutterTransition *transition);

Retrieves the interval set using clutter_transition_set_interval()

Since 1.10

clutter_transition_set_animatable ()

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

clutter_transition_get_animatable ()

ClutterAnimatable * clutter_transition_get_animatable   (ClutterTransition *transition);

Retrieves the ClutterAnimatable set using clutter_transition_set_animatable().

Since 1.10

clutter_transition_set_remove_on_complete ()

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

clutter_transition_get_remove_on_complete ()

gboolean            clutter_transition_get_remove_on_complete
                                                        (ClutterTransition *transition);

Retrieves the value of the "remove-on-complete" property.

Since 1.10

The "animatable" property

  "animatable"               ClutterAnimatable*    : Read / Write

The ClutterAnimatable instance currently being animated.

Since 1.10

The "interval" property

  "interval"                 ClutterInterval*      : Read / Write

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

Since 1.10

The "remove-on-complete" property

  "remove-on-complete"       gboolean              : Read / Write

Whether the ClutterTransition should be automatically detached from the "animatable" instance whenever the "stopped" 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.

Default value: FALSE
