IDLgrScene Properties
IDLgrScene objects have the following properties in addition to properties inherited from any superclasses. Properties with the word “Yes” in the “Get” column of the property table can be retrieved via IDLgrScene::GetProperty. Properties with the word “Yes” in the “Init” column of the property table can be set via IDLgrScene::Init. Properties with the word “Yes” in the “Set” column in the property table can be set via IDLgrScene::SetProperty.
Note: For a discussion of the property description tables shown below, see Modifying Object Property Descriptions.
Objects of this class have the following properties.
In addition, objects of this class inherit:
ALL
An anonymous structure containing the values of all of the properties associated with the state of this object. State information about the object includes things like color, range, tick direction, etc., but not image, vertex, or connectivity data, or user values.
Note: The fields of this structure may change in subsequent releases of IDL.

REGISTER_PROPERTIES
