IDLgrScene Properties

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.

Property Type

REGISTER_PROPERTIES

A Boolean value that determines whether to register properties available for this object. If this property is set, all properties marked in this properties section as “Registered: Yes” will be registered for display in a property sheet. This property is useful mainly when creating iTools. By default, no properties are registered.

For IDLgrScene, the available properties (and their iTool data types) are:
