Notify

Description

Use this callback to manage the interaction between and custom display and Softimage. When there is a change to the selection, a value or the time, Softimage sends a notification that can be trapped by the corresponding notification object.

This callback takes the ViewContext object as input which you can use to get one of the View Notification objects:

• CSelectionChangeNotification —holds information about a selection change event.

• CValueChangeNotification —holds information about a value change event.

• CTimeChangeNotification —holds information about a time change event.
