IDecorator_SetParent() inherits wholly from IWIDGET_SetParent().
- pif:[in] Pointer to the IDecorator object.
- pwc:[in] Pointer to the IContainer object that will act as the decorator's parent, or NULL if the decorator is being orphaned.
void IDecorator_SetParent(IDecorator *pif, IContainer *pwc);
IDecorator_SetParent() should only be called by a container that is managing the decorator.
Decorator must not refcount their parents. It is the parent's responsibility to set the parent pointer of all child objects to NULL prior to the parent being deleted.
