An asynchronous method call which executes the specified delegate and begins an operation to create a new vector (Polyline with two points)
at the location of a series of mouse clicks on the display.
Namespace:
ESRI.ArcGISExplorer.MappingAssembly: ESRI.ArcGISExplorer (in ESRI.ArcGISExplorer.dll) Version: 2.0.0.900 (2.0.0.900)
Syntax
C# |
---|
public void BeginTrackVector( TrackDelegate trackDelegate ) |
Visual Basic (Declaration) |

Public Sub BeginTrackVector ( _ trackDelegate As TrackDelegate _ ) |
Parameters
- trackDelegate
- Type: ESRI.ArcGISExplorer.Mapping..::.TrackDelegate
A tracking delegate that contains a method to be called when the user interacts with the display.
Remarks
The BeginTrackVector method calls a delegate which allows returning a user-clicked Polyline on the map. A vector is a special case of a Polyline with exactly two points, used only in ArcGIS Explorer during tracking operations (there is no vector geometry type). The TrackDelegate allows mouse moves and tracking cancellation to be identified. The tracked Polyline is available from the Geometry passed to the delegate.
This asynchronous method will return immediately, allowing the user interface (UI) thread to continue working. After this method is called, the trackDelegate method will be called when the user interacts with the display.
