Graph node's port problem

GoDiagram (6 and previous)
1

sir

there is a class GoTextNode which i inherited in GraphNode class.
IN GoTextNode class there is properties like RightPort,LeftPort,–etc,
sir when i create a link from a graphnode PORT to other graphnode PORT ,how can i make link from desired PORT from FromNode to ToNode PORT?

Actually i have made a property in GraphNode Class-
public GoPort FromPort
{
get
{

            return base.RightPort;               
            
        }
       

    }

but through it,i can’t find desired port when create link?

thank you

GoTextNode has 4 ports… one on each side. Any of the 4 can be a from port or a to port.

3

but sir how can i detect which port is selected in graphnode?

Is any property or function is available in GoTextNode class to find selected port?
4

“selected” in what situation? on the mouse down of the port that starts the link?

5

sir in graphnode i made a property FromNode to findout selected port

but when i use base. then there is no any property which tell the actual port where selection occured.
so i have to bydefault set base.RightPort that every time takes right port.

Well, GoDiagram doesn’t have the notion of a “selected port”, other than a port that started the linking operation in GoToolLinking.

If you want to add the notion of a "port most recently clicked closest to", you can do that by overriding OnSingleClick and remembering the closest port. (Note that the GoText inside the GoTextNode also wants OnSingleClick, so I think you have to override CreateLabel and add your own custom GoText to do this.)
