Remarks
By default an instance of this tool is installed as a mouse-move tool in each Northwoods.GoXam.Diagram, as the value of Northwoods.GoXam.Diagram.LinkingTool. CanStart calls FindLinkablePort to find a valid "port" element from which (or to which) the user may interactively draw a new link. DoActivate sets up a temporary link and two temporary nodes, one at the start port and one following the mouse.
This tool does not utilize any Northwoods.GoXam.Adornments or tool handles.
This tool conducts a model edit (DiagramTool.StartTransaction and DiagramTool.StopTransaction) while the tool is DiagramTool.Active.
If you want to programmatically start a new user mouse-gesture to draw a new link from a given FrameworkElement that may be a "port" element or may be within the visual tree of a "port" element, set the StartElement property to let FindLinkablePort find the real "port" element. Then start and activate this tool:
myDiagram.LinkingTool.StartElement = ...;
myDiagram.CurrentTool = myDiagram.LinkingTool;
myDiagram.CurrentTool.DoActivate();
