A synchronous (blocking) call returning a new Polygon at the location of a series of mouse clicks on the display, using the specified line color and width while tracking.

Namespace:  ESRI.ArcGISExplorer.Mapping

Assembly:  ESRI.ArcGISExplorer (in ESRI.ArcGISExplorer.dll) Version: 2.0.0.1500 (2.0.0.1500)

Syntax

C#
public Polygon TrackPolygon(
	Color color,
	double width
)
Visual Basic (Declaration)
Public Function TrackPolygon ( _
	color As Color, _
	width As Double _
) As Polygon

Parameters

color
Type: System.Drawing..::.Color

The color of the partially completed line shown during the tracking operation.
width
Type: System..::.Double

The width in pixels of the partially completed line shown during the tracking operation. Default is 1, maximum is 10.

Return Value

A new Polygon defined by a series of mouse clicks on the display.

Remarks

This method returns a user-clicked polygon on the map, using the specified line color and width while tracking.

This method will block the user interface (UI) thread until the user has completed tracking the Polygon. The method can be cancelled if the ESC key is pressed after the method has been called or the CancelTracking()()() method is called; in this case the method will return nullNothingnullptra null reference (Nothing in Visual Basic).

Alternatively you may wish to use an asynchronous equivalent, see the BeginTrackPolygon methods.
