INewEnvelopeFeedback2 Interface

Provides access to members that control creating a new envelope.

Product Availability

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

Members

Description
Read/write property AspectRatio The aspect ratio for the custom constraint type.
Read/write property Constraint The constraint on this rubberbander.
Write-only property Display The display the feedback object will use.
Method MoveTo Move to the new point.
Method Refresh Call this after a refresh to show feedback again.
Method Start Begins a normal feedback at the given point.
Method Stop Stops the feedback and returns the shape. Shape may not be an envelope if the display is rotated.
Read/write property Symbol The symbol the feedback object will use.

Remarks

Start begins the feedback operation and takes the starting mouse location, while Stop completes the operation. The inherited MoveTo method should typically be called for each MouseMove event between Start and Stop.

When the Stop method is called, it will return an IGeometry representing a rectangular polygon, that is, a polygon with four segments in a rectangle.

The maximum and minimum of this rectangle come from the coordinates of the point given with Start and the point from the MoveTo method to be called. As a result, if MoveTo is never called, then an empty geometry will be returned; the IsEmpty property from IGeometry will return True.

The Constraint property allows you to specify how the feedback will behave and whether or not the feedback is forced to have a particular shape. The default value is zero, or no constraint. The Constraint property can be set at any time but will not have any effect until MoveTo is called.
