Interface INewCircleFeedback

All Superinterfaces:

IDisplayFeedback, Serializable

All Known Subinterfaces:

INewCircleFeedback2

All Known Implementing Classes:

NewCircleFeedback

public interface INewCircleFeedback
extends IDisplayFeedback, Serializable

Provides access to members that control the new circle feedback object.

Remarks

This very simple interface has only two methods of its own: Start and Stop. Like the other feedback interfaces, all other functionality is inherited from IDisplayFeedback. The Start method is used to specify the circle's center point, and Stop returns a new ICircularArc. The radius of the circle created depends on the distance between the Start point and the last point used in the inherited MoveTo method.

Note that the ICircularArc, which is returned from Stop, can be converted into an IPolygon by creating a new Polygon object, then adding the ICircularArc using the AddSegment method on the ISegmentCollection interface.

Product Availability

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