OptionalContentMembershipDict Class Documentation

classOptionalContentMembershipDict

Namespace:datalogics_interface

Detailed Description

Form, container, and annotation objects can be associated with one or more optional content groups. By associating them with an optional content group, they become part of that 'layer', and the user can control the visibility of the content.

Note that by placing other element objects in a container, they can also be associated with an optional content group.

An OptionalContentMembershipDict connects content to the OptionalContentGroup; it contains a list of OptionalContentGroups, and rules for determining visibility when the OptionalContentGroups have conflicting on/off states in the active OptionalContentContext.

An OptionalContentMembershipDict cannot be changed once created; you must create a new OptionalContentMembershipDict and change the objects to point to it.
