Interface INewPolygonFeedback

All Superinterfaces:

IDisplayFeedback, Serializable

All Known Implementing Classes:

NewPolygonFeedback

public interface INewPolygonFeedback
extends IDisplayFeedback, Serializable

Provides access to members that control the new polygon display feedback.

Remarks

The use and behavior of the NewPolygonFeedback is similar to the NewLineFeedback; however, the geometry that is displayed and returned is a closed Polygon. This means that when Stop is called, the start point will be added again as the finish point, thus closing the shape. At least three points should be added to the Feedback. AddPoint must be called a minimum of twice after the first point has been added using Start; otherwise a Null value is returned.
