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.

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.

clutter_transition_set_to_value ()

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

Sets the final value of the transition.

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.

ClutterTransition

typedef struct _ClutterTransition ClutterTransition;

The ClutterTransition structure contains private data and should only be accessed using the provided API.

Since 1.10

struct ClutterTransitionClass

struct ClutterTransitionClass {
  void (* attached) (ClutterTransition *transition,
                     ClutterAnimatable *animatable);
  void (* detached) (ClutterTransition *transition,
                     ClutterAnimatable *animatable);

  void (* compute_value) (ClutterTransition *transition,

                          ClutterInterval   *interval,
                          gdouble            progress);
};

The ClutterTransitionClass structure contains private data.

Since 1.10

The “animatable” property

  “animatable”               ClutterAnimatable *

The ClutterAnimatable instance currently being animated.

Flags: Read / Write

Since 1.10

The “interval” property

  “interval”                 ClutterInterval *

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

Flags: Read / Write

Since 1.10

The “remove-on-complete” property

  “remove-on-complete”       gboolean

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.

Flags: Read / Write

Default value: FALSE
