Device Class
This .NET class wraps the OdGsDevice class. The device is the abstract representation of the GUI window where the drawing is displayed. In addition, it responds to operating system notifications, such as window resizing, that are forwarded by the graphics system client. For more information, see Working with Graphic Devices.
