All Known Implementing Classes:

public interface ITraverseWindow
extends Serializable

Provides access to members that interact with the Traverse Window dialog.

Superseded By

ITraverseWindow2

Remarks

ITraverseWindow allows courses to be added to the existing traverse within the Traverse dialog. A current workspace must be being edited for the Traverse dialog to be enabled. Also the current edit layer must be either a Polyline or a Polygon.

The type of course being added to the traverse depends on the CourseType. The esriCTDirectionDistance and esriCTAngleDistance courses create line segments, the esriCTCurve and esriCTTangentCurve courses create circular arc segments. The courses are defined by text values within the MeasureText, CurveParameter, CurveDirectionType and TurnDirection properties.

When the course type is DirectionDistance, MeasureText(0) is the direction of the course and MeasureText(1) is the distance of the course. For a course type of AngleDistance, MeasureText(0) is the clockwise angle between the previous segment and the new segment and MeasureText(1) is the distance of the line segment. For both the TangentCurve and Curve course types, MeasureText(0) is a text value representing the appropriate curve parameter defined by CurveParameter(0) and MeasureText(1) is a text value representing the appropriate curve parameter defined by CurveParameter(1). Any two of the CurveParameters are required to create a circular arc including Chord Length, Arc Length, Delta Angle or Radius. The TurnDirection is also required to indicate if the curve turns to the left or right If the course type is Curve, a text value in MeasureText(2) and CurveDirectionType define the direction of the curve.

Once all of the parameters have been set for a course, IsAddEnabled will test if the values are correct. Add is used to create a new course. The StartPoint needs to be set before any courses can be added. An optional FinishPoint can exist for the traverse.

All Directions and Angles are in the current units specified within the Editor options. Distances are in the current data frame map units, however they can also be entered with an appropriate suffix that specifies the length units. Refer to the IDistanceConverter for more on the converting distances.

To interact with specific controls on the Traverse Window dialog, the MeasureSelected, MeasureHWND and SetFocusToMeasure methods are used.
