Graphics Events
Notifications before and after the repainting of the current Creo+ window. This enables you to overlay your own graphics over the window and ensure that they get refreshed when the Creo+ window is repainted, for any reason.
 These notifications will be called many times; for this reason, your callback routine should be as optimized as possible to avoid performance penalties. For other techniques that may be used to draw graphics, which will repaint with the Creo+ window, refer to the section on Display Lists. Refer to the User Interface: Basic Graphics section for details. |
