3 ClutterActorMeta

Base class of actor modifiers

3.1 Overview

<clutter-actor-meta> is an abstract class providing a common API for modifiers of <clutter-actor> behaviour, appearance or layout.

A <clutter-actor-meta> can only be owned by a single <clutter-actor> at any time.

Every sub-class of <clutter-actor-meta> should check if the <"enabled"> property is set to ‘#t’ before applying any kind of modification.

<clutter-actor-meta> is available since Clutter 1.4
