+ * to control how a #ClutterAnimation will animate a property.
 *
 * Each #ClutterAnimatable should implement the

 * interface to compute the animation state between two values of an interval
 * depending on a progress factor, expressed as a floating point value.
 *
+ * If a #ClutterAnimatable is animated by a #ClutterAnimation
+ * instance, the #ClutterAnimation will call
+ * clutter_animatable_interpolate_property() passing the name of the
+ * currently animated property; the values interval; and the progress factor.
+ * The #ClutterAnimatable implementation should return the computed value for
+ * the animated
+ * property.

+ * SECTION:clutter-drop-action
+ * @Title: ClutterDropAction
+ * @short_description: An action for drop targets
+ *
+ * #ClutterDropAction is a #ClutterAction that allows a #ClutterActor
+ * implementation to control what happens when an actor dragged using
+ * a #ClutterDragAction crosses the target area or when a dragged actor
+ * is released (or "dropped") on the target area.
+ *
+ * A trivial use of #ClutterDropAction consists in connecting to the
+ * #ClutterDropAction::drop signal and handling the drop from there,
+ * for instance:
+ *
+ * |[<!-- language="C" -->
+ *   ClutterAction *action = clutter_drop_action ();
+ *
+ *   g_signal_connect (action, "drop", G_CALLBACK (on_drop), NULL);
+ *   clutter_actor_add_action (an_actor, action);
+ * ]|
+ *
+ * The #ClutterDropAction::can-drop can be used to control whether the
+ * #ClutterDropAction::drop signal is going to be emitted; returning %FALSE
+ * from a handler connected to the #ClutterDropAction::can-drop signal will
+ * cause the #ClutterDropAction::drop signal to be skipped when the input
+ * device button is released.
+ *
+ * It's important to note that #ClutterDropAction will only work with
+ * actors dragged using #ClutterDragAction.
+ *
+ * See [drop-action.c](https://git.gnome.org/browse/clutter/tree/examples/drop-action.c?h=clutter-1.18)
+ * for an example of how to use #ClutterDropAction.
+ *
+ * #ClutterDropAction is available since Clutter 1.8
