public interface IDisplayFeedback
extends Serializable

Provides access to members that control the base display feedback.

Description

IDisplayFeedback is the generic (base) interface implemented by all the FeedBack objects.

Remarks

A reference to an object implementing IDisplay should be set using the Display property prior to calling any of the methods of this interface or interfaces that inherit this interface.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux
