C# Class Smrf.NodeXL.Visualization.Wpf.DraggedVertices

Represents one or more vertices that might be dragged with the mouse.
Create an instance of this class when a vertex is clicked. When the mouse is moved, check MouseDrag.OnMouseMove to determine whether the mouse has moved far enough to begin a vertex drag. If returns true, call to create a Visual to represent the dragged vertices.

Call CancelDrag if the user wants to cancel the drag operation.

Call RemoveMetadataFromVertices when the drag operation completes or is cancelled.
