Could you explain a bit more about this, please? It seems to be
something to do with focus/reactivity, maybe even involving a drawing an
outline of the actor sometimes, though I don't think I've ever seen such
a thing in a clutter program.
static void
clutter_group_pick (ClutterActor *actor,
const ClutterColor *color)
{
/* Chain up so we get a bounding box pained (if we are reactive) */
CLUTTER_ACTOR_CLASS (clutter_group_parent_class)->pick (actor, color);
/* Just forward to the paint call which in turn will trigger
* the child actors also getting 'picked'.
*/
if (CLUTTER_ACTOR_IS_MAPPED (actor))
clutter_group_paint (actor);
}
