MapDisplay..::.TrackMoveGeometry Method (Geometry, Color, Double) |
MapDisplay Class Example See Also |
Assembly: ESRI.ArcGISExplorer (in ESRI.ArcGISExplorer.dll) Version: 2.0.0.1500 (2.0.0.1500)
Syntax
C# |
---|
public Geometry TrackMoveGeometry( Geometry geometry, Color color, double width ) |
Visual Basic (Declaration) |
---|
Public Function TrackMoveGeometry ( _ geometry As Geometry, _ color As Color, _ width As Double _ ) As Geometry |
Parameters
- geometry
- Type: ESRI.ArcGISExplorer.Geometry..::.Geometry
The Geometry to be moved.
- color
- Type: System.Drawing..::.Color
The color of the tracked Geometry while it is being moved.
- width
- Type: System..::.Double
The width in pixels of the tracked line shown during the tracking operation. Default is 1, maximum is 10. Note it does not apply if the tracked geometry is a Point.
Return Value
A new Geometry at the clicked location. The shape is based on the input geometry but translated to the new location.Remarks
This method will block the user interface (UI) thread until the user has clicked on the display. 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).
If you are using this method to move a Graphic or Note remember that you will need to update the Geometry property with that of the tracked geometry to actually move it, see the code example below.
Alternatively you may wish to use an asynchronous equivalent, see the BeginTrackMoveGeometry methods.
Version Information: This method is supported from version 2.0.0.1500.
