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.

• ALL
• COLOR
• HIDE
• REGISTER_PROPERTIES
• TRANSPARENT

In addition, objects of this class inherit:

• IDL_Container
• IDLitComponent

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	Structure
Name String	not displayed
Get: Yes	Set: No	Init: No	Registered: No

COLOR

The color to which the scene should be erased before drawing. The color may be specified as a color lookup table index or a three-element vector [red, green, blue].

In a property sheet, this property appears as a color property.

Property Type	COLOR
Name String	Background color
Get: Yes	Set: Yes	Init: Yes	Registered: Yes

HIDE

A Boolean value or an enumerated list item indicating whether this object should be drawn:

Value	Property Sheet Value	Description
0	True	Draw graphic (the default)
1	False	Do not draw graphic

 

Property Type	ENUMLIST
Name String	Show
Get: No	Set: No	Init: Yes	Registered: Yes

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:

• HIDE (Boolean)

Property Type	Boolean
Name String	not displayed
Get: No	Set: No	Init: Yes	Registered: No

TRANSPARENT

A Boolean value that determines whether to disable window clearing. If this property is not set, the destination object in use by the scene is automatically erased when the scene is initialized.

Property Type	BOOLEAN
Name String	Transparent
Get: Yes	Set: Yes	Init: No	Registered: Yes
