ClutterChildMeta

typedef struct {
  ClutterContainer *container;
  ClutterActor *actor;
} ClutterChildMeta;

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:

1
2
3
4
5
6
7

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 the ClutterContainerIface virtual functions ClutterContainerIface.create_child_meta(), ClutterContainerIface.destroy_child_meta(), and ClutterContainerIface.get_child_meta().
