/**
|
|
* ClutterChildMeta:
|
|
* @container: the container handling this data
|
|
* @actor: the actor wrapped by this data
|
|
*
|
|
* Base interface for container specific state for child actors. A child
|
|
* data is meant to be used when you need to keep track of information
|
|
* about each individual child added to a container.
|
|
*
|
|
* In order to use it you should create your own subclass of
|
|
* #ClutterChildMeta and set the #ClutterContainerIface::child_meta_type
|
|
* interface member to your subclass type, like:
|
|
*
|
|
* |[
|
|
* static void
|
|
* my_container_iface_init (ClutterContainerIface *iface)
|
|
* {
|
|
* /* set the rest of the #ClutterContainer vtable */
|
|
*
|
|
* container_iface->child_meta_type = MY_TYPE_CHILD_META;
|
|
* }
|
|
* ]|
|
|
*
|
|
* This will automatically create a #ClutterChildMeta of type
|
|
* MY_TYPE_CHILD_META for every actor that is added to the container.
|
|
*
|
|
* The child data for an actor can be retrieved using the
|
|
* clutter_container_get_child_meta() function.
|
|
*
|
|
* The properties of the data and your subclass can be manipulated with
|
|
* clutter_container_child_set() and clutter_container_child_get() which
|
|
* act like g_object_set() and g_object_get().
|
|
*
|
|
* You can provide hooks for your own storage as well as control the
|
|
* instantiation by overriding #ClutterContainerIface::create_child_meta,
|
|
* #ClutterContainerIface::destroy_child_meta and
|
|
* #ClutterContainerIface::get_child_meta.
|
|
*
|
|
* Since: 0.8
