Extended Error Information
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.
Interfaces
| Interfaces | Description |
|---|---|
| IActiveViewEvents (esriCarto) | Provides access to events that occur when the state of the active view changes. |
| IConnectionPointContainer | Supports connection points for connectable objects. |
| IDisplay (esriDisplay) | Provides access to members that control the Display. |
| IDisplay3D (esriDisplay) | Provides access to members that control drawing methods specific to 3D displays. |
| ISceneGraph | Provides access to members that control and manipulate the scene graph. |
| ISceneRendererEvents | Provides access to events that occur when a scene is rendered. |
| IScreenDisplay (esriDisplay) | Provides access to members that control Screen Display. |
| IScreenDisplay2 (esriDisplay) | Provides access to additional members that control the Screen Display. |
| ISupportErrorInfo | Indicates whether a specific interface can return Automation error objects. |
| IViewers3D | Provides access to members that control 3D displays. |
Event Interfaces
| Interfaces | Description |
|---|---|
| ISceneGraphEventsDisp (default) | Provides access to events that occur when state of scene graph changes. |
| ISceneGraphEvents | Provides access to events that occur when the state of the scene graph changes. |
| ITimeDisplayEvents | Provides access to members that control Display Time Events. |
Remarks
SceneGraph is to Scene what MapDisplay is to Map. It's associated with a Scene object, either in ArcScene or in a scene viewer control (or a later version scene control). It handles most of the 3D rendering operations and makes the drawing more efficient.
Working with Events
When working with SceneGraph's default outbound interface in Visual Basic 6 declare variables as follows: Private WithEvents pSceneGraph as SceneGraph
When implementing ISceneGraphEvents declare variables as follows:Private WithEvents pSceneGraphEvents as SceneGraphEvents
When implementing ITimeDisplayEvents declare variables as follows:Private WithEvents pTimeDisplayEvents as TimeDisplayEvents
