Interface ICalloutFeedback2

All Superinterfaces:

IDisplayFeedback, Serializable

All Known Implementing Classes:

CalloutFeedback

public interface ICalloutFeedback2
extends IDisplayFeedback, Serializable

Provides access to members that control the callout feedback.

Remarks

A CalloutFeedback may be used to move either the Callout itself or the AnchorPoint. It returns a Polyline representing the new outline of the callout. This polyline can be useful; however, in order to move the Callout, it is simpler to calculate the shift in x and y between the start and endpoints of the feedback operation, then move the callout by the specified amount.

Product Availability

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

Method Summary

void	moveAnchorTo(IPoint point) Moves the anchor point to the given point.
void	start(ISymbol symbol, IGeometry geometry, IPoint point, double referenceScale) Begins a feedback of the given symbol.
IPolyline	stop() Stops the feedback and returns the shape.
