Description
The PropertyGroup object represents a group of PropertyBase objects, (i.e., Property objects and/or Proper-
tyGroup objects). PropertyGroups may be nested to provide a chain all the way from the Layer at the top down
to a single Property (such as the mask feather of the third mask).

Description
This method adds a property with the given name to this group.
Properties may only be added to a PropertyGroup whose propertyType is PropertyType.INDEXED_GROUP.
The only exception to this rule is a text animator property, which is contained in a NAMED_GROUP.
This method generates an exception if a property cannot be created with the given name, so it is always a good
idea to call PropertyGroup canAdd Property() method first to check. (See "PropertyGroup canAddProperty()
method" on page 158.)
The following names are supported:
• Any matchName for a property that can be added normally using the user interface. For example, ADBE
Mask Atom, ADBE Paint Atom, ADBE Text Position, ADBE Text Anchor Point.
• When adding to an ADBE Mask Parade: ADBE Mask Atom, Mask.
When adding to an ADBE Effects Parade, any effect by matchName, such as ADBE Bulge, ADBE Glo2, APC
•
Vegas.
• Any effect by display name, such as Bulge, Glow, Vegas.
For text animators and selectors, Text Animator maps to ADBE Text Animator, Range Selector maps to
•
ADBE Text Selector, Wiggly Selector maps to ADBE Text Wiggly Selector, and Expression Selector maps to
ADBE Text Expressible Selector.
