Description
The PropertyGroup object represents a group of properties. It can contain Property objects and other
PropertyGroup objects. Property groups can be nested to provide a parent-child hierarchy, with a Layer object
at the top (root) down to a single Property object, such as the mask feather of the third mask. To traverse the
group hierarchy, use PropertyBase methods and attributes; see "PropertyBase propertyGroup() method" on
page 145.
For examples of how to access properties and property groups, see "PropertyBase object" on page 140.
PropertyGroup is a subclass of PropertyBase. All methods and attributes of PropertyBase, in addition to
•
those listed below, are available when working with PropertyGroup. See "PropertyBase object" on
page 140.
PropertyGroup is a base class for MaskPropertyGroup. PropertyGroup attributes and methods are available
•
when working with mask groups. See "MaskPropertyGroup object" on page 102.
