polyline connector

[Allen]

How can we capture the x,y coordinates of a polyline connector? i.e the coordinates at the start (tail), joints in between, and head (end) of the connector

Hi Allen, 

 

We suggest you to use below list of connector’s properties/methods to get the head, tail and control (joint in between) points of the connectors. 

 

Properties/methods	Description
TailEndPoint/HeadEndPoint’s “Location” property	Use TailEndPoint/HeadEndPoint “Location” property to get the endpoints of the connectors.
GetControlPoints()	Use Connector’s “GetControlPoints()” method to get the ControlPoints collection and use ControlPoint’s “Location” property to get the control points (i.e. joint in between points).
GetPoints()	Also, use Connetor’s “GetPoints()” method to get the all points (endpoints and controlpoints) of the connector.

  

Code example: 

 

[VB] 

 

Dim pts() As PointF = { New PointF(100, 100), New PointF(400, 150), New PointF(100, 250), New PointF(150, 200) } 

Dim line As New PolyLineConnector(pts) 

 

'tailend point to get the tail location  

Dim tailLocation As PointF = line.TailEndPoint.Location 

 

'HeadEndPoint to get the head location  

Dim headLocation As PointF = line.HeadEndPoint.Location 

 

'GetControlPoints methods to get the controlpoints 

Dim ctrlPts() As ControlPoint = line.GetControlPoints() 

Dim ctrlPt As New ArrayList() 

For Each controlpt As ControlPoint In ctrlPts 

            ctrlPt.Add(controlpt.Location) 

Next controlpt 

 

'Use GetPoints() method to get all points (end and control points) 

Dim linePts() As PointF = line.GetPoints()
