Selection Object (Visio) Published: July 16, 2012 Represents a
subset of Shape objects for a page or master to which an
operation can be applied. To retrieve a Selection object that
corresponds to the set of shapes selected in a window, use the
Selection property of a Window object. The default property of a
Selection object is Item. After you retrieve a Selection object,
you can add or remove shapes by using the Select method. By
default, the items reported by a Selection object do not include
subselected or superselected Shape objects. Use the
IterationMode property to control whether subselected and
superselected Shape objects are reported. You can determine
whether an individual item is subselected or superselected by
using the ItemStatus property.
