public class focus_sem_draw_to_child

extends java.lang.Object

implements traversal_xform

Traversal transformer (see base_interactor.traverse_and_collect) that takes a sem_draw_context and transforms it into a child object's coordinates. This involves modifying the translation on the drawable surface of the sem_draw_context, so that it matches the local coordinates of the child object.
