How to Update Orthogonal Segments in Vue Diagram Connectors?

This article explains how to update orthogonal segments in Vue Diagram connectors. To update orthogonal segments when a connector is drawn dynamically from one port to another, you can utilize the CollectionChange event. When a connector is added or removed, the Vue Diagram connector collection is modified, which triggers the CollectionChange event. This event is triggered twice during the process—once in the “changing” state and again in the “changed” state once the action has been completed.

Below is a code example demonstrating how to update orthogonal segments when dynamically drawing a connectors:

We can draw the connector from the port by enabling draw constraints on the port.

    // Enable draw constraints
   constraints: PortConstraints.Default | PortConstraints.Draw,

When a connector is drawn from a port, the event is triggered and updates the segments of an orthogonal connector when the connector’s state changes to ‘Changed’.

collectionChange: (args) => {
       if (args.state === 'Changed' && args.element.type == 'Orthogonal') {
         let connector = args.element;
         connector.segments = [
           {
             type: 'Orthogonal',
             direction: 'Right',
             length: 70,
           },
         ];
       }
     },
