Description
TrackPolygon returns a geometry object that implements IPolygon.
Remarks
Use the TrackPolygon method within the IMapControlEvents2::OnMouseDown event to rubberband a user defined polygon. The IMapControlEvents2::OnMouseMove event will be triggered during the track, but no IMapControlEvents2::OnMouseUp event will occur. The ESC key on the keyboard can be used during the track to cancel the TrackPolygon.
Calling ITopologicalOperator::Simplify on the digitized polygon will ensure that it is topologically correct.
