Inherited Members

Remarks

This tool supports routing both orthogonal and straight links. You can customize the TemporaryLink as needed to affect the appearance and behavior of the temporary link that is shown during the linking operation. You can customize the ArchetypeLinkData to specify property values that can be data-bound by your link template for the Links that are actually created.

Constructors

PolylineLinkingTool()

Constructs an PolylineLinkingTool, sets PortGravity to 0, and sets the name for the tool.

public PolylineLinkingTool()

Methods

DoActivate()

Use a "crosshair" cursor.

public override void DoActivate()

DoKeyDown()

This supports the "Z" command during this tool's operation to remove the last added point of the route. Type ESCAPE to completely cancel the operation of the tool.

public override void DoKeyDown()

DoMouseDown()

Add a point to the route that the temporary Link is accumulating.

public override void DoMouseDown()

DoMouseMove()

Have the temporary link reach to the last mouse point.

public override void DoMouseMove()

DoMouseUp()

If this event happens on a valid target port (as determined by FindTargetPort(bool)), we complete the link drawing operation.

public override void DoMouseUp()

Remarks

InsertLink(Node, GraphObject, Node, GraphObject) is overridden to transfer the accumulated route drawn by user clicks to the new Link that was created.

If this event happens elsewhere in the diagram, this tool is not stopped: the drawing of the route continues.

This method overrides the standard link creation method by additionally replacing the default link route with the custom one laid out by the user.

public override Link InsertLink(Node fromnode, GraphObject fromport, Node tonode, GraphObject toport)

Parameters

fromnode Node
fromport GraphObject
tonode Node
toport GraphObject

Returns

Link
