Interface IStretchLineFeedback

All Superinterfaces:

IDisplayFeedback, Serializable

All Known Implementing Classes:

StretchLineFeedback

public interface IStretchLineFeedback
extends IDisplayFeedback, Serializable

Provides access to members that control the stretch line display feedback.

Remarks

You can use a StretchLineFeedback object to scale or rotate an existing Polyline object. The scaling and rotation is done about an anchor point. The feedback is moved by shifting the nonanchored end of the polyline by the difference (delta x and delta y) between the current and original mouse locations. The whole polyline is moved to match up with this using a rigid stretch and, as a result, may be both scaled and rotated.
